Amazing Glock Barrel!!

by

Just received my Gspc premium replacement barrel and it is 10x sexier in person!!! Very HIGH quality manufacturing and the recessed crown adds a ton of flavor to your Glock! And the accuracy is on point. Accompanied this with a tungsten guide rod and really set yourself off from others at the range and or competition! Very satisfied and highly recommend this Barrel!

Super Accurate Barrel

Took my Glock 22 40 cal. to the range today to try out my new D D premium barrel with a new steel guide rod.. WOW! I started off at 15 yards and I shot a 1 inch group of 15 rounds. Changed magazines and got the same result. Moved the target to 20 yards and got a 1 1/2 groups. You better get one, they are awesome.

Good barrel but be careful if buying for a Glock 34 with the slide cut.

Recently got this and it looks amazing, but the function not so much. The barrel would snag on the slide cut of a Glock 34 preventing the slide from returning to home location. Took it down to GS and I didn’t even make it through my explanation of the problem before the service guy already new what the issue was. Turns out the barrel was recently recalled for the problem I had. Anyway, he set me up with the new model and I got some extended controls installed and was out. Barrel looks and functions great now.
