Aero Precision M4E1 Threaded Stripped Upper Receiver - Anodized Black - Minor Cosmetic BLEM - APAR700201BC

Aero Precision APAR700201BC: 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 Aero Precision\'s 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. Note: Aero Precision is listing these under a Blem SKU meaning that they will have a very minor cosmetic blemish of some kind that will in no way affect the function of the product. In our experience, this typically amounts to a minor run-in the anodize or a slightly different color variation than the norm. In most cases, we can not see why they are called blems. They have even told us that the blem in the finish could be hidden away due to it being on the internal surface of the receiver. 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 M4 Feedramps .250 takedown pin holes Laser engraved T-marks Includes threaded forward assist roll pin DOES NOT include port door or forward assist Includes: M4E1 Threaded Upper Receiver in Anodized Black
