Description

Meet the smallest addition to our line of AR pistol build kits.  Coming in with a barrel whose length is just 4", this AR pistol build kit is perfect for shorter ranges like home defense. This kit gets you an upper assembly made from a 4" nitride-coated barrel and a 4" M-Lok handguard.  You also get a buffer tube assembly with an SB Tactical pistol brace.  For the lower parts kit, you get one whose grip has been upgraded to a Magpul MOE grip.  Finally, you get one of our 9mm 80% lower receivers.  Please note this lower is designed to accept Glock style mags.
