AERO M4E1-T PRO UPPER RECEIVER GROUP 16 BLK

This complete upper includes our Minimal Optical Deflection (MOD) 4 handguard. The MOD 4 handguard seamlessly blends robust construction with an ergonomic form factor ensuring no compromises between the two. Machined from 6061-T6 aluminum the handguard is engineered with a focus on stiffness to drastically reduce deflection under load. It attaches to the upper receiver via a steel barrel nut which also serves to significantly reduce point-of-impact shift when using an infrared laser aiming device under load. - - A 7-sided M-LOK interface allows the user to customize their handguard to their exact specifications and needs. Lastly each of the 4 QD sockets on the MOD 4 utilize a steel liner to ensure a higher shear load and longer service life with the continued use of QD swivels. - - INCLUDES: - M4E1 Threaded Upper Receiver - MOD 4 15 Handguard - 16 Gov 5.56 Barrel Chrome Lined - Mid Length Gas System Pined Low Profile Gas Block - AR15 A2 Birdcage Flash Hider - Product comes assembled - - M4E1 THREADED UPPER RECEIVER FEATURES: - New enhanced forging that gives the upper receiver a billet look - New picatinny profile that blends seamlessly with our Enhanced Series Handguards - M4 Feedramps - .250 takedown pin holes - Laser engraved T-marks - Includes port door and forward assist installed - - MOD 4 HANDGUARD FEATURES: - Full top picatinny rail for optional attachments - Quick disconnect sling socket at the 3 6 and 9 o’clock positions - Compatible with low profile gas blocks - 1.2 Inside diameter - 1.5 Outside diameter - Compatible with mil-spec AR15 upper receivers and barrels - - 16 Gov 5.56 Barrel: - 5.56x45mm NATO - Cold Hammer Forged - Chrome Lined Finish - .750 gas block journal - Mid-Length Gas System - 1/7 Twist Rate - M4 Feed Ramp Extension - HP and MPI Tested - Standard A2 Flash Hider
