Questions & Answers
will this work on my NFA AR9 lower build with a 22 oz. total weight BCG and Buffer? Expert Answer

Yes, the JP Enterprises Tuned And Polished Buffer Spring could work with that build but the specific model you need will depend on the buffer tube you are using.

Which spring do I need for a psa ar9 with a kynshot Hydraulic buffer? Expert Answer

For the PSA AR9 with the KynSHOT AR 9mm Heavy Damped Buffer, these JP Enterprises Tuned And Polished Buffer Springs for .308 rifles could work. However, I recommend using one of the Blitzkrieg Components Sprinco Power Buffer Springs which are recommend for use with the KynSHOT AR 9mm Heavy Damped Buffer. These springs can be found at the link below.

What Can I Say? It's A Good Spring by Tai, Verified Owner, October 16, 2019
Not much to really say besides that it functions flawlessly in my build. It's a spring. Paired it with Blitzkrieg's 9mm Hydraulic Buffer HD. Works well. I don't hear any metallic sounds. Just a soft recoil.

Bought this spring as part of an overhaul of my 7.62x39mm AR-15 and not only does it provide glass smooth operation but it is also whisper quiet, no more grating twang. Well worth every cent and highly recommended.

Perfect for a long barrel 5.56 build by Mike G, Verified Owner, September 2, 2025
Works like a charm, part of a larger overall solution, but at the end of the day, my rifle has very little recoil and keeps my eye on target, as well as on subsequent rounds—very high quality.
