Velocity Firearms complete dedicated .22 Long Rifle carbine upper receiver assembly for AR-15 and M4. Features a flat top A3 polymer upper receiver with built in Mil-Spec M1913 Picatinny accessory rail with a sling attachment point in the forward assist, A2 flash hider with the correct crush washer, A2 front sight base with bayonet lug, and M4 contour and length handguards with full heat shields. The upper does not include the dust cover. The 16" barrels are machined from chrome-moly, high vanadium steel for long life and are threaded in the standard X 28 TPI. The barrels are of Mil-Spec M4 contour with right hand, 1/16" twist. The 1/16" twist is best for .22 Long Rifle to handle the widest variety of ammo and bullet weights. The barrel, and all external steel parts, are manganese phosphate finished IAW of Mil-STD-171, the U. S. government's recommended protective finish for steel. This finish not only looks great, it affords complete corrosion protection. The bolt is made from high quality 4140 steel and is heat treated to RC46-48 for long life. It also has an electro-less nickel finish that is harder and smoother than other finishes. The electro-less nickel finish helps with function and reliability and makes it very easy to clean.

Includes a ten round magazine ((MAG-087)). Designed to fit all mil-spec lower receivers. Will not work on some Rock River Arms rifles.
