An answer for your ar pistol - ATI Outdoors AR-15 Pistol Buffer Tube Assembly

I installed this on my AR Pistol to keep it legal, reference the new Brace regulations. I reviewed several online videos on how to effectively shoot using cheek weld methods. I have shot 100 rounds using this Buffer Assembly and see the potential of getting very good with rapid accurate shooting using my Red Dot sight. Tip for install, I used a small open face spanner wrench to tighten the castle nut to avoid scratching the finish.
