Description

Ever hear things go bump in the night? Wish you there was a way to stay on the safe side and not the sorry side? Then you need this .300 Blackout Side Charging Pistol Kit. Just mount a flashlight on it, and this little guy is of the perfect stature for clearing rooms in your house if and when you're woken up in the night.

Get this kit, and your build will start with a parkerized 10.5" heavy-profile barrel matched with a 10" free-floating M-LOK handguard. This gives you more than enough space to mount that light on it, while keeping the whole deal small enough to get around corners in your house without banging up the walls or getting caught on stuff. The upper assembly itself is side-charging, and it's also completely prebuilt for ease of installation during your build. See below for more more info.

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 pistol brace. 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.
