New .308 Win barrel arrives for AR-10

Our new JP SuperMatch .308 Win barrel is here! It's a 20" 1:10 twist from their clearance section. I also go a JP High Pressure EnhancedBolt. In this video we have a look at the barrel and then build our .308 Win and 6.5 Creedmoor uppers.

Number 1 pin it sir

[@nc_classics_9610]

Maybe once he shoots some .25 MOA groups, he will pin that sucker in!

[@johnsenuta1038]

Your gonna wish you bought the JP 6.5 barrel after you shoot that .308.

[@mapled3135]

John Senuta so very true. I had a BA barrel that had issues then I got the JP and OMG, what a barrel.

[@byerboys2607]

nc_classics _ lol he pinned my comment but the barrel will pin .25 Moa no problem

[@johnsenuta1038]

Map Led Most people don't know that accuracy is not cheap and buying crap barrels like BA is just that. Cheap.

[@G5Hohn]

DLC: Diamond like Carbon. It’s a plasma vapor deposit coating that is nearly as hard as diamond and nearly glass smooth.

[@david.manser234]

DLC is Diamond like Coating

[@david.manser234]

Good to know. I've been saying it wrong this whole time..lol

[@jacobmccain8082]

I dont think you'll be disappointed. I was worried when I got my 223 that the hype was overblown. I've been blown away by the accuracy.

[@marclarose4512]

Can’t wait to see you shoot some really small groups.... I’m loving this series on the .308!!!

[@PilotMcbride]

When given multiple choices on the phone, always, (repeat) always dial the highest ranking choice. That way you will be guided to the best person for your enquiry. But don't ask to the transferred, best off to make your enquiry with this manager. Works a treat! Make sure they know your name and you'll be remembered. Be polite and sound excited about their product. No hurry up with the reloading/shooting, we're getting very impatient, lmao!!! Cheers from down under mate, very, very jealous of what you're doing :)

[@jordanhays732]

I love the way you say man.

[@benjaminbrown1179]

jordan hays haha... me too!

[@jimhans1]

JRB, glad you chose a barrel. I pray you have better luck with the JP barrel than I did. Now let's go shoot!!!

[@spyderxtra777]

The stripped upper for my .308 Ar-10 project is in the mail! I sure hope you've got a sweet combo worked out by the time my bank account is ready to buy the barrel. In the mean time, I'm just dreaming about 30cal match bullets going into 1/2" groups.

[@CaseySimpsonJD]

Armalite is a proper firing pin / hole diameter too without calling it high pressure. It’s simply the proper smaller diameter. Earlier DPMS were flawed with the larger silly diameter. I easily swapped the dumb DPMS bolt for the right Armalite, solving pressure problems before JP market trick came out. That’s how I solved firing pin hole problems ten years ago working up a 6xc long range field precision setup.

[@TScottW99]

I’m really enjoying the AR10 series. Can’t wait to see how this new barrel shoots!

[@jk3campbell]

I've been to multiple are armorer classes and they always said to set the barrel nut to the lowest torque then tighten until the gas tube notch lines up. That I why there is such a wide torque range. Great videos!

[@jwfreese]

Can’t wait till you get done testing both barrels so I know what to buy... good job

[@toflooryou]

The JP barrels are unmatched but the best reason to go with their HP Enhanced Bolt is that they are properly head spaced to the barrel so you know you are within tolerance, otherwise you are gambling that it will head space correctly. If for some reason the JP barrel won't shoot call their CS department and they will replace it and btw that barrel is polished and not a machine finish. Looking forward to seeing how this shoots!

[@biggerbehindthetrigger2814]

That AR 10 is going to be a nice rifle. I wish I bought the AR 10 that we had at the shop in 2000. I was just not a AR platform rifle kind of guy back then. That's when I had all the money I needed. Now 18 years later I'm kicking myself for not buying it. I bought a Springfield G3 instead. That was a mistake. I couldn't get that rifle to group at 500 yards to save my soul. I gave up on the semi auto and went back to the bolt action. Traded it in for a Weatherby mark V in .30-378. that became my new 1000 yard gun that I took to the Whittington center once a month. I lived in Denver back then so a 4 hour drive and we were there for the weekend. Those were my favorite trips back then. My dad and I would gamble on shots. He always took my money at the rifle range. I took his when we went fishing.

[@AZIROC]

Great choice! Glad you got it

[@mapled3135]

You won’t be disappointed with the upgrade. Trust me, I see a JP 6.5 in the future for you.

[@joelclark2130]

Can't wait to see how the JP Barrel shoots, no I don't think you were a JP sponsor or commercial or infomercial. You just got to get the most bang for the buck out of your equipment. And besides JP knows how this channel can affect their sales you better have some good stuff.

[@300blk8]

That's exactly why I don't do business with people I can't get on the phone lol

[@187Hide]

I'm glade you got this barrel as I have the faxon and I'll compare my notes on accuracy from manufactured ammo

[@fee_lo8346]

DLC. Dimond like coating. Good stuff.

[@MCClownsnose]

Fee_ Lo carbon

[@villenbob]

one thing you could try to save your brass life is put a heavier buffer/ buffer spring, i recently built a AR-308 with a 18" barrel, n have had problems with brass, nasty burs etc. even with factory ammo n Ive turned down the gas 2 steps from not cycling, so I got a heavy buffer from Midway, waiting to get out to the range to try though. ive also got a heavier spring sitting around from the build. I reload my own ammo so i'd like to preserve my brass as long as possible

[@meanman6992]

I was really hoping you would go for the Krieger barrel.

[@jacksonbrewer2030]

As Fee - Lo stated DIAMON LIKE COATING -- I purchased a SHARPS RIFLE CO. DLC BCG, cleans up a lot easier than my other BCG's even NICKEL BORON. I run it dry, makes cleanup even easier with no problems what so ever.

[@glenc4173]

Somehow I knew you were getting the JP barrel/bolt. I can’t wait to see how it groups. :D

[@noretreat151]

after listening to you I know how you felt concerning that phone call..... LOL

[@h3coyote277]

First video I've seen of yours Johnny, great work and I surely subbed your channel. Short, and sweet. Now, I'll jump on the band wagon... Bore-scope it before and after, and shoot it..!

[@greyman1611]

Its now time for the m118lr clone series!

[@jamiewilson343]

About time. Stick with 308 get that hunting load going for this year.

[@CorwinBos]

Good stuff. Lets see some groups!

[@xifogetx]

I was hoping to see a faxon barrel make it into the mix. We all know Krieger will perform and JP is no slouch. But I'd be interested in seeing if there's a trade-off in loss of accuracy with the increased lifespan on the QPQ barrels.

[@geneitzkowitz4710]

You will ABSOLUTELY NEED the HP bolt for the 6.5!!!

[@charrheel3659]

Where did you get your rail segment from to mount your bipod?

[@AkA-me-Kenny2]

It's Sunday oboy. Oboy OBOY! I'm waitinng!

[@terry5008]

A support guy at Sharp's Rifle Company told me that headspace isn't really a thing with AR-type rifles because they're designed to run loose. It's much more important with bolt action rifles. BTW - The Sharp's reliabolt with DLC is pretty nice.

[@MrDennisLB]

In the future, give E.R. Shaw a look for barrels.

[@Gmar69]

Wow, really cool man! Price it now, they are 800 plus...

[@afkirby]

Looking forward to seeing some sub-moa groups out of that thing.

[@alouiciousjackson5812]

It's funny, you have 5 excellent choices listed here and generally couldn't go wrong with any of them. Personally I favor Faxon and Criterion for cost vs. quality.

[@dolanhall1872]

Please scope the barrels first!! Want to see the lands and rifling before shooting. Thx and love the vids!!

[@CaveWyatt]

I went with a Criterion hybrid contour barrel in 6.5 Creedmoor for my Aero M5 build this past winter. Seems fine. The JP Enterprises one-piece has check ring turned out to be the only problem with the build. I guess it’s not meant to be used with a Brownells chromed BCG. All this is to say I was very happy to see the mediocrity of the second .308 video (sorry, I felt like I was rooting against the home team) because I really wanted to see that 6.5 CM barrel installed and shot in the M5. Oh, well...

[@squib3083]

your channel is fantastic

[@SimpleLife1971]

Since it's a 1:10 twist, I suspect it will perform best with 175 grain and heavier tips seated to .025 off the lands.

[@Painterrap]

Sharps Rifle Company has been making DLC coated bolts and carriers for awhile and they are very good. They have a whole bolt and carrier made from s7 tool steel coated in DLC and believe me it’s some superior shit!!

[@THutch556]

JRB the set up looks nice. I’m sure it will shoot better than the last 308 barrel. And I hope it shoots tiny groups for you. With that said I think a lot of people like to compare notes and load along with you, I know I did in the 6.5 Compass series as well as the .223 WOA series. With this particular barrel being a clearance item if it turns out to be a shooter, no one is gonna be able to follow along down the road. Like I said in the last video, My Criterion and Krieger barrels shoot, I’ve never had or seen one that didn’t and that was the reason for recommending them, as going with the JP is a little unknown. (At least for me) What blank is it? Who turns them and finishes them? Are they finished hand lapped? But With that said JP in general is known for putting out quality precision rifles so I’m sure you will be fine, in the event it doesn’t shoot it’s gonna be interesting to see what the customer service is like if they won’t answer the phone. Looking forward to the series.

[@ewetho]

Sweet bolt upgrade! Now get out and shoot!

[@ryanparrish5361]

JP makes good shit!

[@ewetho]

Shoot the best loads from the Thompson Center for break-in loads for the 6.5!

[@WestDesertShooter]

Both look awesome, curious how they will do!

[@oneskypuppy]

Is there a way you could have a "shot clock" going during each 5 shot group that shows real time? Really like the way you edit, but would like to get a sense of what it is taking to keep the barrel cool whether you are using the chamber chiller or not.

[@Jiminico]

I always wonder how long each round cooks in the chamber especially on the semi-autos and when JRB is chasing down brass to check on it

[@garysnyder527]

Interesting undercut at the crown.

[@shakes00lude]

The only problem I see is that nobody will be able to order the same barrel if it turns out to be a real shooter, thats why I voted Shillen. I do look forward to seeing the videos though.

[@alanqtrmaine8175]

I like to add that when i ordered my JP low mass bolt carrier they sent me a low friction gas ring for the bolt. Im sure by looking at the video that your bolt has the low friction gas ring on it compared to the aero bolt regular 3 gas rings.

[@seabeewyo8672]

Ballistic advantage 6.5 Creedmoor will give you. 369 inc groups at 100 with Hornady brass, 123 grain eld match bullet and 40.8 grn of win 748

[@col.strayga1389]

I could of sent you that JP gas block, never used it.

[@sukey62]

Noticed a set of Redding 257 Roberts dies, will we see that sometime?

[@DMIINC2013]

Awesome videos as always. One question, how heavy is the that .308 upper?

[@larrypalmer9635]

Do you think the JP high pressure bolt is worth the money? I feel like this is what I need to solve the problem with pressure signs on my brass when I’m well below max charge in my AR10 .308. No pierced primers but heavy ejector smears.

[@Murderface666]

If they upgraded you to a $200 bolt and the barrel and original bolt cost you nearly $500, then substract the value of the high pressure bolt from the cost and that is what your barrel cost. I suspect the "cryogenic" sales pitch is what killed the barrel.

[@cogunlover5550]

Can't wait for an ar10 video. I pray your BA barrel does good in 6.5. If NOT I am going to be dissapointed.

[@benjaminbrown1179]

DUDE!..... WHATS MINE SAY?...... SWEET!...... WHATS MINE SAY?...... DUDE!!!!!!!

[@mornefouche94]

DLC probably refers to diamond-like carbon/diamond-like coating

[@op25ttfd]

Blah blah blah just shoot the dang thing already LOL I think you can't go wrong with the combo you picked buddy. I am definitely interested to see how you like that gas block I considered purchasing it for my 300 Blackout build but I was not sure about an adjustable gas block because right now I will not be shooting suppressed.

[@robnichols6943]

good choice .. I thought someone just sent you an adjustable gas block that was .936 for the creedmoor build and the 6.5 wasnt 936.. DLC= Diamond like coating

[@garyjohns4711]

JP HIGH PRICED OK BARRELS

[@1Alexville]

Could you scope the barrels before and after the break in process? I am curious to see the difference the "break in" makes. thanks

[@drewhansen429]

You wont see anything. The difference is microscopic

[@xnorcal831x]

Dimond like coating(dlc).....Holy shit that stuff is amazing. Look up vso channel he goes over dlc very well

[@allenflud]

Barrel comments for the algorithm

[@scarter176]

I would like to see an air gauge comparison of all these barrels. That is when the BS walks and quality talks. Chrome process is worthy but really a bit of overkill. May as well get it if splurging on best.

[@f16grinch3]

Trying to decide on a barrel replacement for my 308 and very eager to see you do a accuracy video like you have done already with the previous 308 barrel that you replaced with the JP!! Haven’t been able to determine why you went with 20” vs 22 or 24” since the focus seems to be accuracy? Could you explain your thoughts and take it further than that was the popular vote? I have a 16” barrel and want to have longer range accuracy without trying to build a precision rifle. What’s your thought on the point of diminishing returns on a gas gun in 308?

[@vgl217]

Standard for small firing pin hole at least in a Remington bolt gun is .062. Seems to me there's not really a standard for the ar platform

[@Gizmo_The_Familiar]

should have gotten the criterion barrel, overspent for the JP.

[@azamat_bezhanov]

How do you think, how many rounds bokt carrier may last in jp rifle in 7.62 version😊

[@dotman1334]

looking forward to tight groups for both. and to see if you get cratered primers on the JP Bolt or not. Question on the Brass for each. are you starting out with new brass and fire forming them in the respective barrels, or just using what brass you have on hand from previous guns?

[@meanman6992]

Betting the S means stainless and the C means Cryogenic

[@Jet2416-Reloading]

@Johnny's Reloading Bench - DLC = Diamond Like Coating You already knew that but I just wanted to say it. 😀

[@anchorbait6662]

Spyderco has some DLC coated blades. It stands for downloadable content. Jk, I think it's Dimond-like Carbide. Pretty slick stuff. Hard as a... Well, Dimond

[@johnparrish9215]

Sir, how do you ensure the Reciever face and the Barrel is absolutely square to each other? Also, is it all that important?

[@FullSendPrecision]

WHAT? NO SHOOTING?

[@darianballard2074]

Where the hell is the video where you test these ?????

[@garyjohns5817]

When are going to shoot the JP 308 for groups ?

[@WoodrowWoods2007]

It did seem like a pointless voting video, it was pretty evident you have already made up your mind on the JP. But that doesn't make it a bad call LOL JP is well known for excellence

[@garyjohns5817]

When are going to shoot the JP barrel for groups?

[@ProGunsZach]

How is a Superlative Arms adjustable gas block on the cheaper side?

[@JohnnysReloadingBench]

Is there a cheaper .875" adjustable block? The SA was the best price I could find.

[@ProGunsZach]

Johnny's Reloading Bench I thought you were referring to quality, not price. I’ve had great luck with Superlative Arms.

[@yootoober49]

Bore scope?

[@JCVET18]

Why not 4150?

[@justaregularguy3827]

Not to be rude but this vs a kireger I'd take the Krieger for that much money I'm spending

[@hardtarget2359]

I hope that barrel turns out well. Even though I voted for Criterion. To be honest JP hasnt impressed me much.

[@harmongreeriii4163]

What happened to the jp barrel?

[@jeffyoung2089]

👍👍

[@GodWasAnAlien]

Still prolly cost twice as much as a new Aero barrel retail...why do JP Enterprise's farts cost $50, and any of their shits upwards of $500

[@jacquesbeliveau2716]

You talk wayyyy too much...try to minimize and get to 5he testing assembling sooner. Thank you.
