Assembling an 80% rifle build kit is one of the fastest and most cost-effective ways to make yourself a proud new owner of an AR-15 rifle without registration, serialization, or an FFL purchase.
The lightweight 13.5″ M-Lok free-float rail allows scopes, tactical lights, hand grips, and many other accessories to be attached to your rifle quickly and efficiently. The AR-15 rile kit is an ideal weekend project for build kit beginners. By the end of the weekend, you’ll ensure your family is safe with a finished, unserialized AR-15 rifle.
