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!

No lower included. May be shipped to your door, no FFL required. NEVER PUT THIS ON A RIFLE LOWER THAT IS NOT A REGISTERED SBR!   Be aware of your LOCAL, STATE, and FEDERAL LAWS before ordering. Not for sale to HI.
