Buffer and springs

What is the best buffer and springs for AR15 7.5 / 10.5 / 11.5 in barrel. Thanks in advance

By far the best AR-15 buffer spring set-up I have found.

I am a big fan of the Vltor A5 system with the standard A5H2 buffer. Its about $100 though.

Usual advice re high end springs . best buffer is the one that gives proper function in YOUR gun, using your prefered ammo.
It varies depending on bbl length , muzzle devices, gas port (& erosion the4eof), and particularly ammo.
With my two relevant lowers used interchangably with a new 10,5 and a vetan 11.5, I started out with what came with complete lower\ parts kit respectively - standard carbine carbine buffers, knowing I likely would need to further experement. But surprise, they work fine !
,
And further reality check, short bbl ARs are inherently ammo sensitive , for pressure & pressure curve . ie perfectly tuned for max end of NATO 5.56 spec probably won't cycle soft.223 loads. Conversly tuned for soft .223 will be waay overgassed for hot 5.56 .

Running a Shorty AR requires you to be mindful of what you feed it, not like an 20in rifle or 16in midlength that can be expected to be reliable with virtualy any vaguely suitable ammo.

+1 on Tubbs :thumbsup:

I have them in all my ARs from my 9mm to .300blk in 5", 8.5" & 12.2". My uncle runs one in his .458 socom and it solved a large number of issues include FTF & Slam fires.

Many of these concerns can be mitigated by installing a high quality adjustable gas block such as an SLR set screw click adjustable GB. :thumbsup:

Well yeah, but that wasn't what the OP inquired.

As a thread drift, is there a decent adjustable GI style front sight assy ?

Not that I am aware of. Black River Tactical sells inserts to reduce gas flow in over gassed barrels.

That's a question for SUPER CHAD!(notice reverb)...but not that I've heard of though.

Oh, and hey, you're the one who brought those issues up, not I. :shrug:

Interesting. Not entirely my experience though.

My 10.5" 7.62x39 AR seems to run just fine, even feeding it the cheapest Russian surplus ammo lol.

Running the BCM standard buffer and spring.
