Product Overview

MidwayUSA is proud to offer this AR-STONER™ Carbine Kit at an exceptional price! This AR-Stoner carbine length upper features a mil-spec bolt carrier group, phosphate finish, A2 fixed front sight and a heavy profile barrel. The A3 upper will attach to virtually any standard AR-15 lower receiver and comes complete with charging handle, forward assist, ejection port cover, bolt and bolt carrier assembly. With a 1 in 10" twist, the 16" barrel provides outstanding accuracy with a wide range of projectiles. This pre-ban style upper includes a bayonet lug and A2 flash hider. Supplied without a rear sight, this upper is a great platform for a red dot sight or iron sights (both sold separately).


This AR-STONER™ Carbine Kit also includes a M4 mil-spec 6-position stock assembly. The buffer tube is machined from 6061-T6 aluminum and given a hard coat anodized finish to withstand years of abuse. The 6-position telescoping stock features a built-in sling swivel to mount your favorite rifle sling.


The AR-STONER™ Lower Parts kit includes everything needed to build a complete lower, except a stripped lower receiver. All parts are made to standard military specifications.

Use of steel-cased 7.62x39mm ammunition in the AR-15 platform may result in occasional light primer strikes due to the small diameter firing pin and hard military-style primers. Aftermarket triggers with lighter springs are not recommended.
