.223 Wylde AR 15 Rifle Kit – 16″ Stainless Barrel, 1:8 Twist Rate with 13.5″ M-Lok Handguard

Assembling an AR-15 rifle upper assembly is one of the fastest and most cost-effective ways to make yourself a proud new owner of an black rifle without the added costs of those gun-dealer markups, extra fees, and high taxes.

This kit includes almost every part required, minus the firearm component (a stripped lower receiver), sights, and a magazine. Now you can complete your new AR with entirely custom, handcrafted parts so you can say you built it yourself.

The skeletonized 13.5″ M-Lok rail is ultra-light. It allows scopes, tactical lights, hand grips, and any other accessories to be attached to your rifle quickly and efficiently. This 223 Wylde Rifle Kit is an ideal weekend project for beginners. By the end of the weekend, you can assemble your new shooter and hit the range with confidence knowing you’re holding a quality rifle.
