NEW YORK COMPLIANCE:

It does not, by itself, make your firearm New York Compliant. For N.Y. compliance you must either epoxy over the screw once the CompMag is installed or use another N.Y. locking device.

In New York, often times a mag lock is installed on the firearm, which disables the mag release. The mag can be squeezed by the mag lock device if it is installed too tightly, and will result in the rounds or the follower not moving through the mag properly causing misfeeds. Always check the mag function before using epoxy on the maglock

COMPATIBILITY:

DPMS/SR25 compatible.

Compatible ammunition:  7.62X51 / .308 / 6.5 Creedmoor

Compatible with standard AR-10 type lowers.

NOT compatible with lowers that have a custom or extended magazine well.

NOT compatible with LMT MWS or H&K MR 7.62.

READ ALL INSTRUCTIONS:

When tightening your AR-15 CompMag into the magazine well, be careful not to over tighten it. If it is tightened too much this will cause the rounds to rub inside the magazine and can cause misfeeds. If this happens, simply loosen the screw a bit, relieving the pressure.

Before using, please read the instructions and watch the videos found in the recent posts section on our home page, entitled “Loading and Unloading your CompMag. Clearing Double Feeds.”. This will help you better understand how the CompMag operates.
