This weapon is designed to provide superior ballistics for CQB combat in a very small package. We’ve built a reliable, accurate, and lightweight AR-15 pistol, chambered in the traditional  5.56/.223.  We use a 11.5″ match grade barrel, to get the best balance between short barrel length and effective ballistics possible from the 5.56 round.  With .300 Blackout you can go shorter and still be effective, but with 5.56 this is absolutely the sweet spot!  We consistently get 1-2 MOA from this pistol at 100 yards.

Our weapons are designed to be 100% reliable, accurate, and effective in order to protect you and your family.  The small size and light weight of this AR 15 SBR combined with the power of the 5.56 rifle round, and available high capacity magazines make it a fantastic choice for home defense, a truck or car gun, or for smaller people.

This amazing weapon is built on our precision forged Horizon Arms Research 7075-T6 aluminum receiver married to our truck-proof round M-Lok hand guard.  A top of the line Geissele trigger provides a light pull with quick accurate shots.   We’ve added a Phoenix Weaponry hand stop for safety.  A EOTech red dot optic provides quick target acquisition in a battle proven form.  All in all, we have taken the best components from Horizon Arms Research and the firearms industry at large, and created the best tactical AR 15 pistol possible.

An optional Law Tactical adapter can add a folding stock to this weapon.  It adds a little weight, but allows this pistol to fit into a backpack or storage space in a car or truck.


An SBR version of this weapon is also available.  The images are of the SBR.  The Pistol is the same but with a SBA4 Pistol Brace instead of the stock shown. Given the new ATF Pistol Brace Rule, an SBR may be a better option.
