PWS Enhanced Carbine Buffer H2 Weight


Delivered as promised. Fast shipment. I will definitely shop from Primary Arms in the future.



Fit and Finish awesome..

Not a bad choice


I like that it's Nickel Boron coated and it looks great. It's a bit clacky and noisy and I prefer the Spike's Tactical T-2 powdered tungsten weight buffer better for that reason, but for the price, this isn't a bad option at all! Great, reliable shipping from PA, as usual!

Good quality


I trust pws to do good work and this is no exception. It was more but I know it will do what it is supposed to do and look good doing it.

PWS quality


Like all PWS products I have encountered thus far - I have two of their uppers - I am very satisfied with the high quality of design and manufacture of these products.

F1 Grade Compatible


PWS products are F1 Grade Compatible. Great quality, Amazing Finish.

Great buffer...


Solid construction, well made. I would recommend getting a better spring than stock to get the full benefit. Good value and a good price. I would recommend to anyone!

Top Notch Service without fail!

I bought the PWS MOD2 Carbine buffer to solve an slight overgassing issue on my AR carbine build a couple years ago. This Buffer solved the problem of the extractor damaging the cartridge case rims. A couple of weeks ago I bought a .300 AAC Blackout upper with a carbine length gas tube and this buffer works perfect with my 110gr. supersonic handloads. After 2 years this buffer is still working great. Primary Arms sells great stuff and gets it out the door fast. Thanks Primary Arms!
