Heard a noise in the night and need to check it out? Don't just grab any old pistol. Make your nightstand gun from this build kit, and have extra oompf when you need it.
This pistol configuration 9mm AR is perfect for home defense and super fun to take to the range. You get a 9mm 80% lower receiver that's cut for Glock® mags (not included). Besides a lower parts kit, you get SB Tactical's SBA3 adjustable pistol brace. Finally, you get an upper assembly that comes already prebuilt, so once you finish your lower assembly, you can just attach it and get down to business. You only need to supply mags, ammo, and either sights or an optic of your choice. See below for further details.
