I bought one of their 8.5" uppers. It was a CHF barrel with a 7" keymod handguard. Runs great for me. I only have about 100 rounds through it, but zero problems. Not one single failure to feed (I'm not counting when I couldn't strip a round off a Magpul mag - that was the magazine not the upper) - not one. I have been using with a PSA lower SBR. Ran it both with and without a suppressor. Slow fire and rapid fire. Works as it should.

It was insanely quiet too....running subsonics through a Gemtech GM-45.

As mentioned in other PSA threads, stay away from their PTAC and Freedom uppers.
