Most Helpful Positive Review Vltor A5 buffer
I am currently building a 308 with a vltor A5 system. I didn’t realize that I needed a carbine buffer when I purchased this but I spoke with vltor and they gave me some real good advice on my build so I decided to to keep it and start a new build with this. It seems well made and the staff at vltor are super cool. No hands on experience yet.

A5 system works better

by Hotdogjr, Verified Owner from MD, United States Written on July 19, 2026
I have a BCM lower with their Mk2 buffer system, it came with a T0 buffer. Bought the VLTOR A5H4 to experiment with weights. Landed on H2 or T2. The difference in the 2 brands is the spring size under the rubber bumper but the functionality is the same. A SOLGW 13.7 midlength gas shoots super smooth with the A5H2 and a 15% extra power spring.

Best A5 buffer

by Troy, Verified Owner from NJ, United States Written on June 17, 2026
Can’t beat the A5 system and Vltor makes the best buffers. The A5H3 is great for 10.5 and 11.5 barrels. THIS is the buffer to buy!

A5 Buffer for an AR

by Tom, Verified Owner from NV, United States Written on May 21, 2026
These buffers come in different weights. Useful for tuning you gun depending on the configuration such as barrel length, gas system length, velocity of ammunition. Optics planet had the best price with shipping at the time.
These buffers are specific to the VLTOR A5 buffer system.

fast shipping

Great product, slowed down ROF with frt while suppressed. Definitely recommend A5 buffer system with frt over carbine.

Love the A5 buffers

by Chris, Verified Owner from AZ, United States Written on March 29, 2026
Using an A5 buffer system in my long distance rifle build. Very low recoil, very easy to get back on target. Started with H2 and now moving to H3 for fine tuning the ejection pattern. Very happy with these.

Great Buffer

by Nate, Verified Owner from KS, United States Written on October 23, 2025
I use this in my 11.5" AR with a Forced Reset Trigger and it works great with a suppressor, it slows down the cycling enough to make it reliable and controllable.

Better buffer system

by Gunner257, Verified Owner from SD, United States Written on September 21, 2025
The a5 buffer has an internal spring which positions the buffer weights forward in the buffer body. This leads to more consistent functioning in semi-auto rifles.The buffers are also available in heavier weights than the standard carbine buffers.

Great Upgrade

by Michael, Verified Owner from NH, United States Written on May 21, 2025
I purchased a VLTOR A5 Extended Buffer Tube and A5H2 Buffer (with a Geissele Super 42 Rifle Length Braided Spring and Forward Controls Design Extended Castle Nut) for a 14.5" Pin & Weld Barrel with a Mid-length Gas System and it runs FLAWLESSLY. It's some of the most comfortable shooting I've ever done. I highly recommend the A5 System; it feels super solid and has reduced any B"Bolt Bounce". The only problem with the A5 Buffer Tube is that it does not lock many Stocks is the "#1 Position" due to its overall length, I dont really care about that but some OCD's will,
Pros:
  • Quality
Cons:
  • price
Best Used for:
  • soft shooting
Would recommend: Yes
