Aero Precision M4E1 Assembled Gen2 Upper 10.5" Barrel 9" Handguard

Aero Precision M4E1 Assembled Gen2 Upper 10.5" Barrel 9" Handguard

Aero Precision’s M4E1 5.56mm 10.5" Carbine Upper Receiver comes fully assembled, lacking only a bolt/carrier group and charging handle - the two most popular components for customization. At its heart is Aero’s forged M4E1 receiver that combines the look of a custom billet receiver with "mil-spec" parts compatibility (including BCG and charging handle) and a proprietary attachment system for the included handguard. Aero has fitted the M4E1 5.56mm 10.5" Carbine Upper Receiver with a barrel of high-grade 4150 chrome-moly-vanadium carbon steel chambered for 5.56mm NATO ammunition, so it will safely handle civilian .223 Remington ammo too. The versatile 10.5" length is short enough for an AR-15 pistol build OR for a compact, fast-handling SBR (short barreled rifle) - with the proper NFA paperwork, of course. The longer carbine-length gas tube helps promote reliable cycling in either configuration.

The Aero Precision M4E1 5.56mm 10.5" Carbine Upper Receiver comes with Aero’s latest Gen 2 Enhanced M-LOK Handguard installed. Handguard and receiver form a rock-solid, monolithic platform for mounting accessories, starting with the full-length Picatinny top rail. Plenty of attachment points for installing M-LOK- accessories exactly where you want them, plus QD sling swivel sockets at the 3/6/9 o’clock positions. You can get your M4E1 5.56mm 10.5" Carbine Upper with a 7" handguard featuring a front sight base gas block, or a 9" handguard with a low profile gas block. Texture milled into the flats give you a better grip and add to your gun’s unique appearance.
