The M4E1 Threaded Upper Receiver features a new angular machined design that helps it stand apart from standard mil-spec upper receivers. This upper receiver features the same enhanced body profile as their M4E1 Enhanced Upper Receiver but is threaded to accept a standard AR15 barrel nut. It is forged from 7075-T6 Aluminum and precision machined to work with all mil-spec AR15 parts.
The M4E1 Threaded Upper Receiver is designed to pair perfectly with their new M4E1 Lower Receiver, giving you a billet looking receiver set at a fraction of the billet price.
Features:
New enhanced forging that gives the upper receiver a "billet look"
New picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards
Review by Peter C. on 30 Dec 2021review stating Rainier: best pro gun shop in the firearm biz.
Rainier is without question the best online firearms and accesories retailer in the gun biz. Great selection, prices and industry leading customer service.
Review by Abel P. on 14 Nov 2020review stating Excellent Upper
Not stock, but not a $200+ custom upper. Has a beautiful, but slight touch of modernity and design to separate it from the mil-spec tubular upper. Aero Precision is a great company with good products, and Rainier is in its top class of service, faster and on target than OpticsPlanet.
