.223 Wylde AR 15 Rifle Kit (16" Parkerized Barrel 1:8 Twist & 15" MLok Handguard, Side-Charged)

The M4-profile 4150 CMV barrel in this rifle kit provides MOA accuracy, thanks to a new .223 Wylde chamber that better handles .223 Remington and 5.56 NATO. Now you can safely shoot both. In addition, we went with a free-float, lightweight M-Lok handguard that provides plenty of rail estate for that bipod, tac-light, front BUIS, and other kit. All other standards come mil-spec in this rifle kit: An M4 buttstock pairs up with a Carbine buffer, M16 BCG (works with the side-charging handle with no modifications) and mil-spec trigger, housed inside a 7075-T6 forged flattop upper.

What’s Included

This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with buttstock. It does not include the component to make a firearm: A stripped lower receiver. Pair this rifle kit with an AR-15 80% lower receiver and AR-15 jig to fabricate a receiver, sold separately.

Here's the beginner's guide to 80% lowers.

Receiver sold separately

No FFL or serialization is required to fabricate a receiver under federal law. However, state laws vary. Some states require serialization or have banned 80% lowers and gun-making kits. We encourage each and every builder to perform their own research about the state and federal laws that apply to them.
