Pistol caliber carbines have seen a bit of a resurgence over the last year with the introduction of the CZ Scorpion EVO, the Sig MPX, and new HK MP5 clones. As you might expect, there are companies looking for a way to tap into the pistol caliber carbine segment through some interesting avenues. American Manufacturing Group sent us their Lock, Stock, and Barrel conversion kit for the Glock 17 to try out.
Sliding the barrel into the slide is just like inserting the factory barrel except you need to remove the locknut and piston to fit the barrel through the hole. As you can see in the photo below, there are three ports in the barrel to provide the needed gasses to assist the slide in operation.
Once the barrel is in the piston/bushing is slid over the barrel with the narrowed portion extending into the slide to keep everything centered. The next step is to thread the retaining nut over the threads, tighten it down to keep everything in place then back it off enough to center the lock screw over one of the flats in the threads.
The kit comes with a heavier recoil spring assembly for Gen 1-3 Glock 17s; the kit did come with an adapter for Gen 4 pistols, but the instructions recommend that you retain the stock unit instead.
Attaching the stock is a simple operation, pull the latch and rotate it 90 degrees to retract the pin and slide the frame plug into the empty grip hole. Then make sure the back of the frame clips into the top portion and insert the pin through the lanyard hole. The entire process only takes a few minutes from start to finish making it a rather easy conversion.
With an MSRP of $299.99 the buy-in price is a bit steep, but again, the group that this kit appeals to is very small. If you are looking for a carbine kit for your Glock that will fit into a backpack there aren’t many options out there. You can learn more about the kit on the American Manufacturing Group’s website HERE.
