Reviews & Ratings for Adams Arms PZ Complete 5.56 Upper Receiver — 1 review — Page 1

Put this Adams Arms PS 1 upper on a PSA lower build, absolute great match, nice tight fit. I’m completely sold on the piston system, ran a hundred rounds through the rifle on the initial trip, flawless operation, mounted a cheapie red dot on it and put the rounds where I wanted them at fifty yards. Really wanted to see if all the talk of piston system ran cleaner, the tear down for cleaning proved that, no carbon build up on the BCG, simple wipe down sufficed. Did notice a bit more recoil compared to my other AR? Had heard and read people doing the retrofit using the Adams piston conversion kit we’re having some problems with FTF, FTE. Don’t know, could be several variables at play there. I’m glad I purchased the complete upper, had fast response from the company on all the questions I had, I had questions on the warranty if purchased through a second party and not factory direct, they stand behind their product to the original purchaser regardless of where you buy. Give another review at the thousand round count.
