This Complete AR upper receiver includes the Radical Firearms M-LOK Hybrid Rail System which offers a generous 1.8” inside diameter that easily accommodates most suppressors. Lightening cuts along the rail reduce weight and aid in rapid cooling while M-LOK mounting points and MIL-SPEC Picatinny continuous top and short bottom rails provide space for your favorite sights, optics, and accessories. Features anti-rotation tabs, non-rotating QD sling mounts, and a tough hardcoat anodized finish.

If you are looking to get into semi-automatic big bore hunting for an affordable price, pick up this Radical Firearms complete upper, drop it on any existing Mil-Spec lower receiver, and head to the range to start lobbing these heavy bullets down range. The slower 1:14 twist rate combined with the short barrel make for an easy to carry AR that will be accurate for short range hog hunting.
