The highest quality upper for the money...

Rating
100%

The fact you can get such a high quality piston upper for this amount of money is amazing.

The machining and finish are top notch. The handguard has an excellent fit and is indexed directly with the receiver so it will never move. It charges extremely smooth and balances well with an 11.85" barrel.

You get an excellent upper, and excellent handguard, and excellent piston system, and excellent gas adjust system, and excellent Raptor charging handle, and and excellent bolt. You won't see many companies making parts at the level PWS is for the same cost. And if you do; you definitely won't get a bolt or charging handle.

I just put an ASR FH on it and can't wait to suppress this.
