GREAT BARREL

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!

Money well spent

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!

Perfect Size

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.

Makes for a nice range toy

Headspaced cleaned and lubed for a test run. Paired with my GM upper receiver. Cycled a little rough at first, smoothed out after running some ammo through it. Makes for a good pistol.
