Lewis Machine and Tool Flat Top Barreled AR-15 Upper Receiver - 5.56 - 16"
Details
This Lewis Machine & Tool M4-style Flat Top Barreled AR-15 Upper Receiver ships complete from the factory with the front sight gas block, delta ring, forward assist, and dust cover already installed, giving you a 16" carbine-length foundation ready for a two-piece handguard.
Features:
- 16" chrome-lined barrel chambered in 5.56 NATO, 1:7 twist
- Carbine-length gas system
- Phosphate-finished exterior
- Forged aluminum flat-top upper receiver, hardcoat anodized
- Laser-engraved T-marks on the picatinny rail
- A2 front sight gas block and delta ring installed
- Forward assist and dust cover installed
- Compatible with Mil-Spec AR-15 lowers and parts
The laser-engraved T-marks make it simple to return an optic to the exact same position after removing it, and the chrome-lined bore adds corrosion resistance for long-term durability. Because the front sight gas block, delta ring, forward assist, and dust cover all ship pre-installed, there's less assembly work standing between you and a finished upper.
At 16", this carbine-length-gas configuration gives you the traditional M4 handling characteristics LMT is known for, built to accept two-piece handguards for shooters who prefer that classic profile over a free-float rail.
Lewis Machine & Tool has supplied the U.S. military, law enforcement, and government agencies with precision-engineered weapon systems since 1980, and every LMT upper is made in America to that same standard.
