Ratings & Reviews
Bought this upper to complete a build I was in a hurry to finish. Overnight shipping was a success. Went home the next day and attached it right to my finished lower and everything lines up beautifully. Haven't had the chance to shoot yet but I have no doubt it will perform wonderfully.
Had Some Issues
by Bryan -
I got one of these at a really good price. I had an issue with the forend rail, it was too snug getting a Troy front sight on, like it was cut too big, so I exchanged it. The new one had the same issue so I just got over it and greased up the sight and rail and pushed it on. Additionally the BCG is the roughest looking that I've got now, for whatever that matters, tons of tool cut marks in and out. Shot fine though and it was really inexpensive when I bought it so I can't get too torqued about it's issues, but I've got lower bid uppers that gave me a better intial impression.
