DefencePort DRM-12 12 Gauge 20-Round Drum Magazine For MKA 1919 / AR12 Shotguns

This is a DefencePort DRM-12 20-round 12 gauge drum magazine for AR12 shotguns.

Compatible with all AR-style and MKA 1919 semi-auto shotguns, the DefencePort DRM-12 12 gauge 20-round drum magazine is the first mass-produced 12 gauge drum magazine in the world.

The aluminum tower delivers a snug, wobble-free fit, while the polymer drum and cover provide unmatched strength and corrosion resistance for lasting service in any tactical or target shooting application.

Additionally, the high-strength steel spring and polymer follower work together to ensure smooth, jam-free operation, and the precision-machined feed lips provide a snug fit for reliable feeding performance with most 2.75” 12 gauge cartridges.

So, don’t wait. Pick up a few spare drum magazines for your AR12 shotgun from GunMag Warehouse.

Note: This drum may not fit some bullpup 12 gauge shotguns due to the angle of the pistol grip preventing access to the magwell for drums. Bullpups vary, with some readily accepting the drums and others being awkward in regard to insertion and extraction. Use caution when ordering for use in an AR-12 bullpup.
