NOT HAPPY
I had this product for a lil over two years and have put less then a thousand round through this gun I have multiple ar15 and this is the only one I bought through this company and the gas key has already became loose and I have a adjustable gas block so it's not being over gased as a traditional block is wide open I dont believe that the product is garbage I do believe it's just isnt as hard as they say mili spec when I shot more then multi other from bravo,Kaiser and falcon that I havnt had a si gel issue with and have more then a 1000 round on them I did try to contact them via email and it's only been one day with no response so hopefully soon enough they will help resolve this issue Cons: GAS KEY BECAME LOOSE IN LESS THEN 1000 ROUNDS
