Great prices and quality products. July 20, 2025 : JP Morgan from Mississippi   This is an excellent weight to begin with when you're fine tuning the recoil and and cycle rate. Works well with most calibers and forced reset triggers. Fast shipping and excellent communications! Thank you once again! Was this review helpful to you?

Exactly what I needed May 5, 2022 : Steve Daniels from Buchanan, TN United States   Been thru spec buffer 3oz and heavy buffer 4.7oz. The WOT trigger didn’t like either. This ran the trigger. Still need to fine tune it with buffer spring maybe, but it’s close. Great product. Quick shipping. Was this review helpful to you?

AR-15 Carbine Buffers April 26, 2022 : Andy from Eldridge, IA United States   I purchased a carbine upper that was way over gassed and needed a heavy buffer to remedy the issue. A lot of vendors sell H1 and H2 buffers for 25 to 40 dollars each but MAS Defense buffers are available at a much more reasonable price.  I purchased the MAS H1 and H2 buffers and the quality is top notch.  They look, feel, and function just like the high dollar units. The H2 solved my problem and spent cases are landing in the 3 to 4 o’clock area. I highly recommend the MAS buffers and based upon this experience would not hesitate to purchase other MAS products for my firearms. Was this review helpful to you?
