Most Helpful Positive Review A must for LR308’s or 6.5’s
Don’t do what I did when first being suggested in using the A5 buffer system. Had several companies that all said to find a 308 carbine buffer. You need an AR15 buffer with a AR10 build. 24 inch Rainer MOD2 308 ultramatch barrel, Aero upr/lwr, Sprinco orange spring, 6.7 oz buffer, & adjustable block. Results…. Sub 1/2 MOA and kicks lighter than a M16A2.

Vltor a5 buffer

by John, from TX, United States Written on February 11, 2021
Great fit and finish. Yes it’s more than a standard buffer but my ar pistol runs smoooooth now! I fit it with a vltor h2 buffer and I couldn’t be happier. Shipping from optics planet took a bit longer than normal, but hey, what’s normal these days?
Pros:
  • Reduced bolt bounce/ felt recoil
Cons:
  • price
Would recommend: Yes

buffer tube extension

by CHRIS URSINY, from PA, United States Written on April 17, 2020
good item to upgrade your ar-15 lower to a vltor a5 type or style, this is slightly longer than a milspec carbine buffer tube so you need to use vltor a5 buffer and rifle length spring to operate correctly.
Pros:
  • Quality
Cons:
  • None
Best Used for:
  • AR15
Would recommend: Yes

Great receiver extension.

by fat raptor, Verified Owner from MI, United States Written on May 12, 2018
This is a very high quality receiver extension. I would recommend getting the a5 tube over this one though because you can close a stock further on it. had very good threads on it and a nice snug fit with my stock.
Would recommend: Yes
