Description

When it comes to home defense (or sometimes just impressing people at your local range), shorter is better because of the added maneuverability.  When it comes to acquiring your own shorty for home defense and turning heads at the range, it's even better to say you built it yourself.  We're giving you that opportunity.

This build kit will get you an AR pistol chambered in 9mm.  You get a prebuilt upper assembly with a 4-inch barrel and a 5-MLOK handguard.  You'll just need to add back-up sights or optics of your choice.  You also get SB Tactical's SBA3 adjustable pistol brace.  Finally, you get a 9mm 80% lower and all the internals to install into your build.  All in all, this kit is an excellent choice for making your home and loved ones a little safer.
