The WARMP45 features a machined billet upper and lower receiver as well as a 6061 T-6 7.25″ M-LOK handguard. The WARMP45 is compatible with standard AR-15 barrels, trigger groups, handguards, furniture, and modified bolt carriers.

The lower receiver is fully ambidextrous which includes an ambi safety, ambi bolt catch levers, and even ambi magazine release buttons and paddle release. The paddle will release the magazine and pressing the magazine button on either side of the lower receiver will also activate the paddle release and release the magazine. Controls will be extremely familiar to anyone who has used an AR-15, and the controls are designed to be reached and operated by the pistol grip hand. Including Schmid Nickel Teflon 3.5lb Trigger.
