The M1337 by Nopel is a 3D printed Gatling gun chambered for 5.56. It uses six AR-15 barrels and six modified AR-15 bolt heads and firing pins. Other than this, the gun is fully DIY, including a fully DIY delinker, fully DIY clutch system and even printed belt links!

Now you can build this marvel of 3D2A engineering with our M1337 Complete Kit! Our kit does all the hard work of gathering the large amount of hardware required for this build.

Our kit includes:

• Every single nut, bolt and spring
• Every single bearing, including the hard-to-acquire main bearing
• Every single rod and pin, each cut to the correct length – no cutting required!
• All six AR-15 barrels
• All six AR bolt heads and firing pins, each properly modified according to Nopel’s instructions
• Six properly milled cam pins
• A milled metal sear
• Six metal 3D printed striker bodies and six milled striker posts
• A metal 3D-printed receiver cam section for increased build life
• Six bolt carriers pre-printed in nylon
• A barrel collar printed in nylon, sized properly for the included AR-15 barrels
• All required parts for both the DIY tripod or the DIY bench mount

This carefully designed kit will save you tremendous amounts of time in your build, and will help ensure your build is successful without extensive tuning.
