Frequently Asked Questions
No, 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.
It depends, we recommend using all Aero Precision parts in your EPC to avoid potential compatibility issues, but the EPC is compatible with a variety of different parts.
We do not recommend the use of aftermarket bolt catch designs or accessories as this can create a malfunction with the last round bolt hold open mechanism.
The EPC-9 receivers are compatible with 9mm and 40S&W.
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 milspec upper receivers.
No, the EPC-9 is caliber specific and is only compatible with 9mm/40 parts and components. 10mm/45 parts and components will be launching in the future.

Yes, you can, so long as your suppressor is rated for the caliber you intend to shoot, and you do not use a Nielsen Device/booster assembly as the EPC uses a fixed barrel.
7.7oz
The EPC utilizes a direct blowback system, which directly uses the kinetic energy generated from the discharge of the cartridge, to push the bolt back and cycle the action.
A last round bolt hold open, a feature built into the EPC upper receiver, allows the bolt to be locked open on an empty magazine.
Aside from not including parts already installed on the lower receiver, each EPC lower parts kit that incudes a fire control group, utilizes hardened trigger pins to meet the high demands of blowback AR platforms.
The larger bore diameter of the 9mm requires a 9mm specific muzzle device that allows proper clearance for the projectile. You will also need ensure the muzzle device is the appropriate thread pitch for your specific 9mm barrel (all Aero Precision 9mm barrels use 1/2x28 threads).
No. The EPC-9 bolt carrier group will not accept hardware commonly used in folding stock adapters.
