Most Helpful Positive Review 9mm buffer

Great delivery great product. Works exactly as advertised. Only wished I had bought two. When you need the right buffer and spring only the right one will do!perfect for the nine millimeter carbine or other pistol caliber carbines. A little heavy for the 308 or 762x39.

Good product for anything 10 in or greater

by jason, Verified Owner from IN, United States Written on August 13, 2025

I tried this kit with a PSA Department of energy 7 and 1/2 in 9 mm pistol caliber carbine and it had absolutely no effect on reliability. It may have even made it worse. If you're using this for anything under 10-in Barrel you're wasting your time and money. My next step is the maximum roller blade blowback if that doesn't work I'm done with it

Pros:

Nice overall kit for a 10-in or greater setup

Cons:

Will not work with anything under a 10-in barrel as far as fixing reliability issues.

FM PCC 9mm buffer

by Ken L, Verified Owner from NJ, United States Written on March 21, 2024

Took the chance and bought this 6.5 oz buffer with 308 carbine Recoil spring. The thing worked great. No issues. Before this, I used a 5.4 9mm buffer with carbine length recoil spring and had many issues with ejection. This combo solved all the issues. You should give it a try!

Pros:

Just works

Cons:

None

Best Used for:

9mm AR15

Excellent Spare

by Guinn, from GA, United States Written on March 17, 2023

Ordered for a spare as can never tell the way things are today as to determine when parts will be available in the future. Guess I am wondering when things will become scarce for the gun lovers in this country just trying to be prepared.
