Description
Adams Arms 16″ (Black only available unless you upgrade) 5.56 Piston M-LOK Carbine Tactical Complete Upper AR-15 MLOK
We at Valhalla Tactical Supply have Adams Arms factory made uppers! (We install the handguard and muzzle device.)
Adams Arms complete piston uppers are chosen because they deliver a practical, drop-in way to get the durability, cleaner operation, and gas-system tunability of a short-stroke piston AR without building a rifle from scratch. They’re especially attractive for suppressed shooters, high round count users, and anyone who wants fewer fouling/heat problems in the receiver — at a modest cost in weight and price compared with a comparable DI upper.

Adams Arms Piston AR Upper Receiver Features and Specs (from Adams Arms):
“- Melonite coated barrel: Melonite coating reduces internal barrel friction which extends the barrel life. Melonite coating also improves accuracy due to tighter coating tolerances and improves muzzle velocity by over 100 FPS. With no chrome lining to flake or peel over time, these melonited barrels will outlast hard chrome lined barrels two to one!”
This is a complete upper which includes a bolt carrier group and charging handle.
Please allow 2-3 weeks to cerakote the handguard for FDE or ODG versions. Black Anodized is available to ship right away!
