Double Diamond Premium Replacement Barrel

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!

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.

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.

Baught gs dd premium barrel for my 19 build love it

Received the barrel and replaced the dasan 2 port in a G22, along with a 20lb Tungsten Guide Rod. I purchased the gold barrel and discovered that it has a satin finish, not the shiny finish displayed in the picture. Rapid fire from 15 yards resulted in 1 1/2 to 2 inch groups. 25 yards 2 to 3 inch groups, (slow fire). Downside it's a little pricey but very accurate. Overall this barrel displays a high degree of craftsmanship and quality.

Just received my barrel for my Glock 19 4gen, and the accuracy is good.

I bought the stainless steel Double Diamond Premium along with the tungsten steel guide rod assembly and of course the are just drop ins for my Glock 22 40 cal. I was really astonished at the difference in accuracy and less muzzle flip. A lot more smother the gun would shoot . I highly recommend both these products together.

Awesome! Major upgrade over factory barrel in accuracy, performance, and looks! The quality and finish is second to none and the pictures just don't do these barrels justice. Reloaders, have no fear! These barrels eat anything from premium factory loads to hand poured and loaded swc without any issues and beg for more, all while keeping 1"-1 1/2" at 20yds! One of the best upgrades I've done to my gen 3 23.

I recently received the Double Diamond as a Xmas gift..
Unfortunately, today was the first day with it. I consider myself an better than average shooter. Always practicing trying to group with 3” at 7yds. & tighten up even more. You know if it’s this barrel Wow I was grouping 2 1/2” at 7yds. I moved the target down range to 15yds and to my amazement I was grouping at 4”. This DD barrel is a keeper and will order one for my everyday carry. I was reading that barrel changing hand no effect on grouping they’re wrong it does. I had a gentleman next to me shoot a clip and he too was amazed! Thank you Lenny and group for your amazing product!!!

Received a Double Diamond Replacement Barrel from the Magill's Glockstore and wow. It fits nice and tight, the machining is excellent and has a nice high polished finish beyond anything I could have expected. I hope to get out real soon and see how my shot groups have improved!

Took my p80 builds to the range, one had a brownells black nitride barrel, and the other a ss DD performance barrel…. I was hitting everything with my g19, I had a 90% accuracy rating with my dd barrel and a 70% accuracy with the brownells. I will definitely be buying more of these. The finish on these things are amazing, with they had the gold ones in stock, and had one that has that case hardened look to it.

I purchased this barrel for a polymer 80 G 19 build. Before purchasing us I have never purchased one of Lennies barrels and was a little nervous I won’t lie. But after the build was complete went to the range to test fire this gun and I know people will say that you cannot get any better accuracy out of an aftermarket barrel then you can out of the stock Glock barrel. But I’m here to tell you that this barrel is spot on! I was literally cutting paper in the bullseye between rounds at 10 yards. ( rapid fire) So I’m giving this barrel five stars so thanks Lenny for such a great product although I wish you would’ve made the premium barrel and a 26
