FM Products PCC 9mm Heavy Buffer 6.5 oz w/ .308 Carbine Recoil Spring
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.

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.
Would recommend: Yes

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
Would recommend: Yes

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.
Best Used for:
essential spare parts
