Aero Precision M4E1-E 18" 6MM ARC Complete Upper - Anodized Push the boundaries of precision with the Aero Precision M4E1-E 18" 6MM ARC Complete Upper. Purpose-built for shooters pursuing accuracy at extended ranges, this upper pairs the proven M4E1 Enhanced platform with the ballistically superior 6MM ARC cartridge for outstanding performance in the field or on the line. M4E1 Enhanced Upper Receiver Precision-machined from 7075-T6 aluminum, the M4E1 Enhanced upper receiver features Aero's proprietary threaded handguard interface that eliminates the traditional barrel nut. This design delivers a stronger, more consistent lockup while streamlining the overall profile. The anodized finish provides lasting durability and corrosion resistance in any environment. EM15 Enhanced Handguard The EM15 Enhanced Handguard threads directly into the upper receiver, creating a rigid, monolithic feel with clean lines and zero flex. M-LOK slots at the 3, 6, and 9 o'clock positions offer versatile mounting options for lights, lasers, grips, and other accessories without adding unnecessary bulk. The slim, free-float design promotes accuracy and keeps weight in check. 6MM ARC Advantage Developed by Hornady for precision applications, the 6MM ARC delivers match-grade accuracy and supersonic performance beyond 1,000 yards from an AR-15 platform. The 18" barrel extracts maximum velocity from the cartridge, making this upper an ideal choice for precision rifle competition, long-range hunting, or designated marksman roles.
