Well built. threads need help. - Guntec USA AR-15 Mini Trident Flash Can

I didn't buy this out of necessity. I bought this just to see/hear how it works... and to make my Beretta 21A look silly. The threads had a bit of a burr though, and I didn't want to use the Bobcat barrel as a tap... so I've ordered a tap to clean the threads up. Not a big deal. I will probably run into more uses for a 1/2"-28 tap in the future. Will return to this review once I've tried it on the little Beretta and my Glock 26. I certainly don't mind it being aluminium as it isn't a muzzle device that deals with significant pressures.
