Aero Precision Launches EPC-9 Pistol Caliber Carbine

Aero Precision has launched their new EPC-9 pistol caliber carbine. The EPC (Enhanced Pistol Caliber) is Aero Precision’s leap into the world of pistol caliber AR platforms, featuring a full lineup of AR9 style parts and accessories. The EPC shares some of its features with Aero Precision’s flagship M4E1 line of products.

The Aero Precision EPC operates on a straight blowback system and does not require a gas block and gas tube as traditionally found in other AR15s. The direct blowback system directly uses the kinetic energy generated from the discharge of the cartridge, to push the bolt back and cycle the action.

The EPC-9 Lower Receiver is compatible with standard frame GLOCK G17/G19 pattern magazines. The EPC-9 accepts most AR15 barrel nut/handguard combos that are compatible with Mil-Spec upper receivers.

Receivers

The foundation of the EPC product line is our EPC-9 receivers. These receivers are machined from custom 7075-T6 aluminum forgings and include all proprietary parts installed from the factory. These proprietary parts include the following: magazine release, last round bolt hold open assembly, and ejector.

Bolt Carrier

The Aero Precision EPC-9 9mm Bolt Carrier Group is machined from 8620 steel and featuring a nitride finish, fracture resistant grade 23 titanium pin, and 4140 steel extractor, the EPC bolt assembly is precision machined from the ground up to meet the extreme demands of blowback AR platform firearms.

Barrels

The barrel is arguably one of the most important components in your build. Aero Precision has a full lineup of 9mm barrels that are compatible with the EPC and other AR9 platforms. These barrels are manufactured with the same quality and attention to detail as our AR15/AR308 you know and love. Each Aero Precision EPC barrel is designed to work in a direct blowback system. This means there is no gas port, and no need for a gas block and gas tube!

Buffer Assembly

The EPC buffer kit is optimized for the use in the EPC and other AR9 platforms. Featuring a custom 7.7 oz buffer and m5 carbine spring, our EPC buffer kits are designed to meet and exceed the demands traditionally brought on by blowback AR9 platforms. You can purchase the EPC buffer and M5 carbine spring standalone, to use in conjunction with a mil-spec buffer tube of your choice, or as a part of a kit including our enhanced buffer tube.

Lower Parts Kit

Each EPC Lower Parts Kit comes with all the small parts you need to finish your EPC build (detents, springs and optional fire control group and grip). These kits do not include the proprietary components for your lower receiver, as they are pre-installed from the factory. The components in our lower parts kit are mil-spec with the exception of the trigger and hammer pins, which are hardened to meet the demands of blowback AR9 builds.

*NOTE: If purchasing a third party trigger assembly, we advise using a trigger designed specifically to be used in a AR9 platform.

Handguards and Furniture

The EPC-9 upper receiver utilizes mil-spec threads, meaning it is compatible with most handguards that will fit a mil-spec AR15 upper receiver. This includes our full lineup of ATLAS handguards as well as most third party AR15 handguards. The EPC-9 lower receiver is compatible with most AR15 pattern grips.
