How to Adjust AR15 Buffer Weight | Palmetto State Armory

[@sethperry1323]

U guys should look into making a bomb proof 10 position adjustable gasblock that doesn't cost 200 +.... I love my riflespeed but my God... I'll have over a GRAND in gasblocks if I just put them on my main ones....

[@PalmettoStateArmoryVideos]

Not a bad idea!

[@AndyE30]

​@@PalmettoStateArmoryVideosAgreed. Something with a detent rather than the freely rotating screws.

FAXON just came out with one. Think it’s 13 position and it’s $80. Just got 2 in the mail yesterday 🤙🏼

[@martincolvill5453]

Thank you very much. I'm at that point of looking to fine tune my ARs ( including a PSA one I traded for). This was helpful.

[@PalmettoStateArmoryVideos]

Glad we could help!

I have the G$ H2 buffer on my M4 Block II and it feels pretty good. I upgraded to the H3 buffer for my mk18 and felt more enjoyable to shoot.

[@David-if4vj]

I just got a silent buffer kit, it would jam my AR every 2-3 rounds so this video was super helpful.

[@prodigy6000]

Gas port size in each barrel is different, causing over gas or under gas. bullet weights/loads, any weight added in front of the receiver changes the inertia/kinetic energy of a semi auto.A lot of variables to consider this is why a lot of custom company's have adjustable gas blocks after all these years. but you have shown the basics to get most in the right direction.

I have a 16in PSA chambered in 5.56 unsuppressed. Would you recommend the H1 or H2?

[@jeff-i7x]

Wish PSA put some the buffer kits on a daily deal flash sale . The LPK are getting ridiculous on price just for a basic kit. I would have bought from PSA but AR Discounts got yall beat on price for in house brand.

Which would be best, new buffer or silent capture spring?

[@xCaPz]

Do different buffers use different springs at all? Or is it all the same?

Building an 11.5 AR pistol. Lower comes with the carbine buffer weight. I plan to suppress so seems like H3 is the way to go. Shooting 556

What weight do you recommend for a 10.5 Carbine unsuppressed? I’ve been running a H2 buffer but been having FTF issues lately

[@carlitosway368]

What are your thoughts on changing the buffer spring as well, change first or find best buffer first and play with spring strength after?

[@alexuram5984]

So a good starting point for my 14.5" Daniel Defense M4A1 would be the H2? Planning to run it almost exclusively suppressed. I have a case of 5.56 55gr ammo but will soon switch to 65 or 77gr

Informative. Would you recommend, as an upgrade, a different buffer for your (that I own) 16" M4 Carbine-Length 5.56 NATO 1/7 Nitride Lightweight M-Lok Classic Rifle?

[@PalmettoStateArmoryVideos]

Your buffer weight isn't so much an upgrade as much as it is tuning. If you're running a 16" 5.56, the standard buffer weight should work properly if you're using standard 5.56 ammo without a suppressor. If you're running subs with a suppressor, you may need to adjust your buffer weight. There's no hard and fast rules, just what works best for your build.

[@ar-15techtipsinunder5minut8]

@@originalthundercat4295 lol, thanks but the material the bumper is made out of is critical to the operation of the gun and needs to meet mil spec so that it doesn't over compress causing the BCG carrier key from hitting the lower receiver. My guess is these cute colorful bumpers aren't even close to what Colt uses.

Send us a dm on one of our socials. We would love to hear more and help!

[@PalmettoStateArmoryVideos]

You can always upgrade your charging handle. We use the Radian Raptor handles in our Sabre line.

[@frankiescott5428]

if you mean the handle itself, then it could just either need a good breaking in or an upgrade. if you mean the spring feels/sounds gritty, just clean the spring + inside of the toob

[@scottster25]

ive heard white grease on the spring, buffer, and tube can help. if youre talking about hearing grittiness in the tube and not the charging handle itself

[@ronniegrumbles-ok3jw]

What would be a good buffer to start with to make a 8” pcc shoot a little softer. Using a 2.95oz buffer now.

[@PalmettoStateArmoryVideos]

More weight should help reduce some of the recoil!

[@mikecollins8241]

I have 2 PSA lowers, one was sold as a "pistol" lower (with brace) the other was a "rifle" lower(w/stock).. I'm curious what (factory) buffer is used on each? I suppose I could just take them out, but I'm curious if they are set up differently from PSA.. "pistol" is a 12.5" barreled 5.556, the "rifle" is a 18" 6.5 G barrel.. both seem to run fine right out of the box FWIW..

[@HurtStrongTactical563]

Great video! I have the PSA 10.5 ar15. What do you suggest for me to run it suppressed ?

[@PalmettoStateArmoryVideos]

[@ronmartblog]

If the bolt is skipping over the round in the magazine then that means the buffer is not heavy enough, right?

[@PalmettoStateArmoryVideos]

It could be the buffer or the gas block. Try tuning the gas block first.

[@vintagemotorcyclerepair4052]

Very informative! Thanks!

[@PalmettoStateArmoryVideos]

Glad it was helpful and thank you for watching!

[@tallspy7150]

What I just gathered... If im shooting subs, I should be getting a lighter weight buffer not heavier.

[@PalmettoStateArmoryVideos]

Shooting suppressed (with standard ammo) typically INCREASES the back pressure, meaning there's more gas entering the gas tube to cycle the AR. If you're running a 16" with a suppressor and standard super sonic ammo, it's common to INCREASE the buffer weight to counteract the increased pressure.

[@tallspy7150]

@@PalmettoStateArmoryVideos correct. But does that mean that I should be lowering the weight with low pressure subsonic ammunition?

[@P0rtScann3r]

Yes, subsonic ammo has less pressure and needs a lighter buffer weight to cycle. Keep this in mind for cycling pressure when considering buffer weights: Super Sonic>Subsonic Suppressed>Unsuppressed Shorter gas tubes>Longer gas tubes

[@P0rtScann3r]

Keep in mind there are many ways to balance/tune a system. If you plan to switch between suppressed and unsuppressed and/or between subsonic and super sonic frequently, you may be better off with an adjustable gas block like a superlative arms or a riflespeed than constantly switching buffers. If you are just switching between suppressed and unsuppressed, and you have a flow thru our low back pressure design, you may not need to change anything on your gun to tune it.

[@P0rtScann3r]

Also, for a better shooting experience, get a Tubbs flat wire spring, Geissele braided spring, or a JP Enterprise silent capture system.

[@virenpatel9973]

11.5 .750 gas port 55g/62g. Unsuppressed for now. Will be down the road. What should I run? PSA lower. It feels too violent.

[@pormansgoldpmg5493]

What buffer weight do u recommend for the PSA AR-V 7" barrel when suppressed. Added Rugged Obsidian 9 suppressor and it over gassed. PSA factory buffer is 5.5.....Should I buy a 7.5 ounce or a 10 ounce? Very expensive buffers and don't like guessing.

[@jonathonmaloney9953]

Nice buffer video. Are your springs like the dagger spring where you offer a 15 an 18 and a 20 for a better bolt carrier system?. While were here can we get a PSA 94? Basically an AN-94 only PSA made. Calibers 5.56, 300 BLKOUT, 6.5 grendel, 7.62, 5.45. Please and thank you.

red buffer in video is h2. red buffer on site is h3. which is correct? or there seems to be a psa h2 buffer and a sabre h2 buffer which are different colors/weights

That would be the Sabre H3 buffer. The weights would still be correct. Colors may vary from line to line and brand to brand.

Gen 3 PA10 16", blows primers out on regular basis. I tuned the gas and bought a sprinco orange spring. Any advice? H3 buffer?

[@PalmettoStateArmoryVideos]

The H3 should do the trick.

[@geodkyt]

If you're blowing primers out on the regular, you have a problem that isn't related to your buffer setup - the max pressure in the case (what causes primers to back out or blow out) is long before the bullet ever passes the gas system. Try different manufacturers or lots of ammo, because that's a sign of either excessively hot ammo, or primers that are too loose in the primer pocket (either primers slightly undersized, pockets slightly oversize, or primers not seated correctly).

[@TheSethxy]
