Aero Precision M4E1-E 16″ 22 ARC Rifle EM15 Complete Upper – Black Anodized

Precision Redefined for the 22 ARC Platform

Push the boundaries of long-range performance with the Aero Precision M4E1-E 16″ 22 ARC Complete Upper. Engineered for shooters who demand sub-MOA accuracy and superior platform rigidity, this upper leverages Aero’s Enhanced series architecture and the advanced ballistics of the 22 ARC cartridge to deliver reliability and precision—whether on the range, in the field, or in competition.

Features

• M4E1 Enhanced Upper Receiver: Machined from 7075-T6 aluminum with a Type III Class 2 black anodized finish. Features Aero’s threaded handguard interface that eliminates the need for a traditional barrel nut—ensuring an ultra-rigid connection between the receiver and rail.
• EM15 Enhanced M-LOK Handguard: Directly threads into the upper receiver for unmatched rigidity. Offers M-LOK slots at 3, 6, and 9 o’clock for optimal accessory placement. Slim and ergonomic for enhanced handling.
• SPR-Profile 16″ Barrel – 22 ARC Chambered: The Special Purpose Rifle (SPR) profile barrel is optimized for accuracy and recoil balance. At 16″, it delivers ideal harmonics and velocity retention with the flat-shooting, high-BC 22 ARC cartridge.
• Rifle-Length Gas System: Smooth cycling and reduced felt recoil, especially beneficial when running a suppressor or during extended strings of fire.
• 22 ARC Cartridge Advantage: Designed by Hornady for precision and terminal performance, the 22 ARC provides greater retained energy, flatter trajectories, and less wind drift than traditional 5.56 NATO—while remaining compatible with standard AR-15 lowers and magazines.
