Tips on building a reliable 7.62x39 AR-15

[@Patrick-od2zc]

You hit the nail on the head for making a good reliable AR-47. Key part's that need to great quality BCG, enhanced firing pin, C Products Defense mags, and well made M4 feed ramps. Great video. I love my AR-47 so much fun to shoot.

[@joshv06]

Thank you so much! My older brother has 10.5" 7.62x39 SBR and we learned along the way what works and what doesn't so I thought I'd bring along what we've learned to a video. I love my 16" x39 build and they are definitely as reliable as any other AR I've had.

[@homesteadhomie1418]

m4 feed ramps cause bolt breaking and cracks on a 7.62x39 round.. its not even close to the proper feed ramps.. they need to be 300 blackout ramps or they will ruin the bolt every time.. M4 feed ramps on a ar-47 platform is like having a grenade in your hands..

If you need a reliable Magazine check out new multi caliber magazine UNIMAG which cycles eight different calibers to include the 7.62 x 39, and it looks like a AR magazine and not a AK banana style magazine. Made to fit AR lowers work great got my UNIMAG from Primary arm. Made by Ross Defense Systems

[@Go2Sleep87]

You just need a good Mil-spec hammer spring & an enhanced firing pin to shoot Russian primers. You could buy an extra power hammer spring like I did but you shouldn’t need it to shoot Tula or any other Russian steel case ammo.

[@albertpeters3897]

Great video. I am in the process of building a Ar15 in 7.62x39. didn't know about Tula ammo. Thanks for the info.

[@sharedpollard4407]

After a lot research watching videos like this… I went with an H2 buffer, carbine buffer spring, Enhanced Power Hammer Spring , Battle Rifle Arms 762x39 bolt installed on an existing Aero Precision BCG, Faxon Mid-Gas 16” barrel, Aero Precision Adjustable Gas Block, DuraMag 28rds, Aero M4E1 lower, Aero Enhanced Upper, Aero Quantum Handguard, Magpul UBR Gen2 Stock, Law Tactical Folder, Kaw Valley ASR mount, and Omega 36m.

[@eligosnick5806]

Ross Defense Unimag for AR 7.62 x 39. The round to be fed sits above the lip of the magazine unlike any other brand I have tried.....

[@erikp2510]

"The only ammo that gives us problems is the cheapest most common and easy to find everywhere "

[@jonnylinzmeier2001]

So I just got a radical firearms AR 15 chamber in 7.62x39 I believe it has a traditional straight walled mag. It could have a block but I believe it’s a 10 round mag and I can’t get more then six in. I also wanted to see how it chambered before I fired it, chambered a live round and wanted to see how it ejected and it wouldn’t. I had to bang it against my leg and yank the charging handle. I took it back to the gun shop I got it from but the owner didn’t know much about it. He cycled one and when it came out the lead was in my barrel but the brass ripped out and powder went every where. I explained to him what I’ve read and heard and he didn’t know just offered to send it in and a new one shipped. From what I can tell it’s hitting just below the barrel but the bolt is jamming it into the barrel in an awkward position. And on top of that I also believe the ramp it came with is somehow off, it gouges the lead and flattens the very end of the brass. My brother shot two rounds and the 2nd sparked all over our target making me believe the ramp is bending the case slightly sending powder down rang with my lead. I also tried a different buffer spring thinking mine was bottomed out or not working properly but even with a new spring had the same issue, even when hand loaded then closed the bolt. But I know the round fits good in the bolt carrier so not exactly sure what’s going on. Any idea on what’s going on or how to fix this

[@NoWr2Run]

Sounds like a Short Chambered Barrel.

[@robertarellano6409]

H3 buffer good for this build

[@handymannapa]

Thank you for the informative video! My setup is slightly different. I'm running 30 round cpd and d&h magazines with a h2 buffer and xp spring both from kaw valley. Feeds flawlessly and locks back everytime.

[@joshv06]

Thanks man! Yeah a heavy buffer weight will definitely slow down the cyclic rate like an adjustable gas block would.

[@joshv06]

Badass. We have an H1 buffer in our 10.5" setup to deal with the added back pressure suppressed with the shorter barrel.

[@carloszerino380]

If you want to get rid of those ugly Russian looking magazines and make your AR look like a AR try the first multi caliber magazine called the UNIMAG. It cycles eight different caliber cartridges without making any adjustment what so ever. Ready to use right out of the package made to fit a AR lower platform works great using the 7.62 x 39 and it looks like a standard 30 round AR magazine. Check it out on Primary Arms.

[@jagrgreen8123]

I bet you work for them

[@JohnProph]

sometimes wolf IS Tula lol. Wolf gets ammo from numerous places

[@jonsebastian1366]

I use an H2 buffer and a .308 carbine spring. Improves function and reduces recoil. I have used a 7.62x39 Colt since 1992, when they were the only one and this kid wasn't even a gleam in daddy's eye. I use Tula all the time. Tula, Wolf, Bernal. It's all good.

[@joshv06]

I was born 1992. So I guess I was a gleam in my daddy's eye :P. A .308 spring increases the forward bolt velocity. Sure it will work, but a standard carbine spring will work better once your mags get dirty from blowback and there is increased drag in your magazines (since the magazine is non-traditional and not optimized for the platform like an AK mag in an AK or an AR mag in an AR). Your magazine stack is already feeding up slowly as it is and having a standard carbine spring will ensure the slowest forward bolt velocity to give the round more time to get to the top of the magazine to be ready to feed.

[@davidmcnerney3048]

I run the same barrel with a red x BCG.Palmetto LPK with there EPT trigger and a WOLFF XP buffer spring.I modified my feed ramps to be more like one big ramp and she runs Tulammo 154g SP'S and every other ammo even rusty old Wolff I had layin around

[@dsclaiborne31]

I've got one of these in a carbine length and am building another in mid length using the faxon barrel with f marked a2 front sight and a vg6 gamma 300 blk muzzle brake. The midlength one will have an aim surplus qpq nitride bolt with lifetime warranty and the other carbine length one I have a toolcraft qpq nitride bolt with it. Both will have elftmann service triggers. The one with faxon barrel will be my home defense gun. It'll have a yhm upper and spikes tactical punisher lower with bcm enhanced parts kit. It'll have troy flip up rears and an xs tritium white stripe front. The optic on it will be an aimpoint pro with American defense mount and 3x magnifier, it'll have a battle arms development badass safety lever and a bcm ambidextrous gunfighter charging handle. On the carbine length it's a er shaw phosphate hbar on an ar stoner upper and Anderson lower with ar stoner lpk. I'm going to use it for hunting and plan to use an American defense recon mount with a Leatherwood hilux cmr 1-4×24. I only use cpd mags in 20 and 28 rounders. The carbine length one has functioned flawlessly with tula, monarch, brown bear, Chinese, it seems to like red army standard best. Golden tiger I initially had light primer strikes on because I had a 4 pound hammer spring on it. When I changed the hammer spring out for standard milspec spring golden tiger no longer became an issue. I am still amassing parts for the midlength faxon build and hope to have it completed around spring or summer 2018.

[@Moofasa1211]

great video, sorry the idea is lost on me at 3:10 ish when you talk about 5,000 rd bolt breaks...

[@joshv06]

7.62x39 bolts have less support material on the bolt lugs, so the lugs crack quicker. The lugs (and therefore, bolt) last about 5k rounds before you have to get a new one.

[@chaplaincrabtree6881]

Says a guy who makes it to the range 3 times a year and shoots a total of 200 rounds. A lot of the arm chair commandos like to theorize about how they will use the gun, but few ever will. 5 thousand rounds of 7.62x39 ammo is around $900. .300 black is about $2750 for 5k rounds. Just so that's in perspective for you. A $70-$100 bolt is a drop in the bucket when you look at ammo costs.

[@aaronl2606]

CMMG fixed this with the Mutant - Powerbolt - Uses a shortened and lightened AR10 bolt.

[@dynamousa4945]

Great video young man

[@SMOKEPOLETV]

As a guy with experience with the platform, what do you think about the PSA KS47 compared to the CMMG Banshee? Do you think the bulky bolt carrier is worth the extra money?

[@4g63mark]

With an enhanced steel firing pin and a drop in 4 lb trigger I get light strikes 10% of the time with Tula. I have a titanium firing pin on the way that might do better..... We'll see.

[@christopherklebon7205]

What buffer weight are you running? I have the same barrel and a JP adjustable gas block. Can't get the bolt to lock back on last round even with gas block fully open. I have a 3.3oz buffer in it now, seems like i may need to go heavier to slow the BCG down.

[@NoWr2Run]

H2

[@waterboy239]

5.3 oz works well

[@jamesclemons3815]

New to gun building in general!! I just built a 7.62 and mine was having over gas problems so I swapped some weights out to make an H3 buffer now I’m having a failure to eject. Need to check my extractor but with less than 20 rounds through the gun I’d like to think it’s not broke yet but still very over gassed? It’s a 7.5 build so I know gas is the main factor. Pretty lost on why it’s doing it. I only have Tula ammo to test right now as well

[@joshv06]

How does the extractor look?

I built a 450 bushmaster ar, everything was the same as 223/556 but the bolt & barrel. Upper & lower & trigger & buffer are all interchangeable. Is the 7.62x39 build the same, or is there differences in the upper & lower?

[@b.anthony9214]

The .450 only shares the same BCG I think, that’s all.

[@MrHrKaidoOjamaaVKJV]

Excellent review. Yes the C Products Defence magazines are the way to go. Many have found that's it's best to Avoid ASC AR 15 magazines in the 762x39 caliber. A Wolf AR15 TRIGGER Spring is a smart move to install in an AR15 lower when shooting Harder Primed Russian/ Surplus ammo.

[@bcjdwbiernfjherwfbowfib]

Poly coated seems better for storage.

[@deluxejake3860]

Any tips/advice for feeding issues on one of these ARs in 762? I do not have light strike issues I have the enhanced firing pin and hammer spring installed. I am using ASC magazines.. I know you mentioned to use CPD mags but I heard from many people those give issues as well. Was curious if anyone knew of any other possible fixes for feeding issues. I have a side charger setup from BCA

[@joshv06]

I would go with an adjustable gas block or heavy buffer to slow down the cyclic rate.

[@perception-reception]

Yea good video idk why 300 blk out has become so crazy. You can't find the ammo or if you do you pay Crazy money for it. 7.62x39 is a great alternative but definitely has more recoil IMO.

I agree. But x39 has about 15% more energy than 300 blackout at half the cost.

Wouldn't a light weight carrier be fine with an adjustable gas block? Cycle speed shouldn't be a problem with that setup.

[@CommonSenseUncut]

Wdym by carbine buffer minimum? I'm building an AR47 with a Noveske KX3 on a 10.5" faxon barrel, geissele H2 buffer with the braided +power spring. Im currently waiting on an adjustable gas block from PSA rn butthe barrel came with a pinned gas block. Do you think it'll run fine without the AGB? Gonna be running a mix of brass and steel cased ammo. Cproduct mags, toolcraft polished NiB m16 carrier/AIMsurplus NiB 7.62 bolt w enhanced firing pin have me rather confident any problem will be with the gas system, but I did have to polish my feed ramps already, the faxon I received had some burs on the ramps

[@joshv06]

I meant that to not take the weights out or to use any lightweight competition style buffers. Not having an AGB will work, but an AGB will slow down the cyclic rate to make sure the roughy has enough time to feed.

[@CommonSenseUncut]

@@joshv06 I figured I'd use both solutions. The buffer system I picked up should take up some of the sharpness of the recoil and improve lockup timing without messing with the gas system but I figure there would still be some tuning necessrry so I grabbed an AGB to be safe. Both should be fine right? Only reason I'm conscerned is bc I heard faxon gas ports are a little small for 7.62

Correct I am using a gunner profile barrel by faxon. Even though they market it as a somewhat light barrel, you gotta remember that you have a 30 cal bore. So it's more rigid than a similar weight 5.56 barrel.

The only thing you should be concerned with is replacing the bolt extractor/springs. It does take more damage with the bolt, but Iv only replaced 2 extractors from cheap bolts over 6k rounds, so 3k sounds about right on extractor life. It’ll be just as reliable as a .223 build just the given downsides of steel case and less materials in bolt/extractor. I will note that Iv never broken a bolt yet just extractors on 7.62x39 bcg.

Were your CPD 28’s a little sticky at first? If so, what did you do to smooth them out?

[@joshv06]

I noticed on 2 of mine that I had to break the spot welds on the inside. They were making the rounds drag. Use a polymer tool to push the follower all the way down and back up. If you feel drag (compared to a working mag), then you need to hit the spot weld on the inside spine of the mag with a flat head screw driver and a hammer.

I love it. shoots cheap russian steel very accurate, reliable, and i do not plan to change the "furniture" at all. did not want a chrome lined barrel as they are less accurate, i don't use corrosive ammo, and I clean my gun. Yes it is a heavy barrel and i prefer it that way. the barrels are rated .7 to 1 moa. the gas port works perfect with no failures. Also right now classic firearms is selling them for $399. now if you want to go out and spend 3x that price or do a custom build go ahead. I don't and as i am not a professional gun smith. furthermore bear creek arsenal backs up my rifle with a lifetime warranty. so in my opinion fuck building one. now if you think your going to build one to be a bad ass sniper then your stupid for not just going ar10 with a full size cartridge. a $2000 one won't make you a better shooter. I am not a gun snob do not want a bunch of bling. I am going to buy 1 more because it is an awesome shooter and the price is very, very good. Have you even tried the BCA rifle and gone shooting with it? lets see you do that and go to the range and make a vid doing a fair side by side comparison.

[@eiji81]

It won't shoot better than a good AK, I promise you that. Reliability wise (accuracy is another story). AK47's are made to shoot 7.62x39 very reliably with almost any ammo. My Russian AK will shoot thousands of rounds with barely any oil or cleaning with Tula or Wolf or whatever. AR builds in x39's can be reliable, but not as reliable to AK's.

@@geocow5105 Flash cans are wasted barrel length. Wouldn't you want to have the added 2.5" to go towards more muzzle velocity, less flash, less muzzle blast? Add 2.5" and you're at a 10.5" barrel. Go with a 10.5" and a flash hider.

What adjustable gas block did you use?

[@shawnaadams8698]

You said that was the faxon barrel, is it a 1/8 twist? How does it compare to a 1/10?

[@joshv06]

It''s just as good. The 1/8 is actually better for subsonic rounds that we make.

[@joshv06]

I see no difference. Good thing is that the 1/8 would be better for the custom subsonic 220gr loads we make. Something tells me that Faxon 7.62x39 barrels actually use a .308 bore..

[@stevenscaccia4979]

Only bear for me has been trying to get subs to run in a 7" pistol gas upper. You guys played with shorties/ pistol gas at all? Adjusting your A1680 load to accommodate?

[@joshv06]

We've only worked with 10.5" and 16" barrels. Are you using a suppressor with your subsonics? I highly suggest going with heavier bullets. I like leather head 220gr RN. With this load, I use 12gn AA1680.

[@stevenscaccia4979]

Thanks for the suggestion, I will try them next go around. I am not ordering from that other company ever again, their customer service is garbage.

Maybe this is a dumb question but I don't know anything about 7.62 builds, but can you run any lower and upper combination you want with this build aside from the parts mentioned? For example a lower and upper for a 5.56 build ? thanks for you time.

[@joshv06]

Correct. All of the parts are the same except for: Bolt/Firing Pin Mags Barrel Bolt carrier groups come with the correct bolt and firing pin. We have everything I used in the video (minus the lower) at www.skidtactical.com/store

[@InYeshuasHolyName]

What type of crappy suppression is that..... sounds darn near the same as without the suppressor 😂😂😂😂 U should wet it 🤔

[@joshv06]

AAC SDN6. You can't tell the difference because your laptop speakers don't go up to 167db for the sound of unsuppressed. Which suppressed is 135db. You're not supposed to wet a rifle suppressor due to the immense pressure.

[@constitutionalrepublican1611]

joshv06 idk, ive used wire pulling gel in my rifle suppressors, works pretty good. ... In different cans. Wire pulling gel can be found at Lowes home improvement stores. They may have a hard time locating it as its not an everyday seller, as most wires do not need that anymore.... Does make a nice difference until the can is real hot as the gel will get real liquidy after a bit.

You're posting a video handing out tips on how to build a reliable rifle..... Then advocate (more like try to sell me) a bolt that lasts less than 5 thousand rounds. Do you understand how ridiculous you sound? How bout instead of providing decenting opinions on my channel, you do some more research, invest FAR more money on training so it doesn't look like a 7.62x39 rifle isn't absolutely kicking your ass, and take the thousands of hours required to understand exactly how ridiculous your standard for reliability is.

you lost all credibility when you think M-4 feed ramps are sufficient for a 7.62x39... there is your only one issue.. replace those ramps with 300 blk out. you may be a fan of this weapon platform but you really should do more research and further your education on a proper working AR-47 platform.. i stopped the video at that point for there is no need to continue because i will most likely tear this video apart further.. i recommend you rebuild your wrong build weapon and then try the video again..

What’s m4 feed ramps ? Is that in the upper reciver? Cuts ?

[@joshv06]

Correct. Because the magazines are not as optimal as 5.56 in a 5.56 magazine (shower feed rate) and the nose of the bullet sits lower than 5.56 due to its larger diameter case.
