Gorilla Machining AR-15 5" Micro 5.56 NATO Barrel | Micro Gas System 1:5 5R Kit | Black Nitride

love it from the packaging to the product nice work excellent craftsmanship great customer service

I bought two of these for the shop...One was a basic AR-15 pistol, and the other has a Sylvan Arms folding mechanism. Both will make GREAT "Back Pack" guns!

Very happy with this barrel. Unmatched quality. Purchased the Tiger Rock 4" handguard and the as the Raw Anchor Harvey Upper as well. Decided to keep short and used a knurled thread protector to finish it off. I'm ecstatic with the results. See for yourself!

I have not had this gun built. The barrel is the perfect size. I always wanted one that was less than 7 inches. I only ever found .22 cal barrels shorter than 7". You can tell it's a quality product once you hold it. This is one purchase that I am glad I made.

Would give 5 stairs but it gave with non standard roll pin for gas tube bent and deformed easy other then that barrel is good buy
