Years ago I had taken an AR pistol on trade at a gun show. The owner was honest and told me up front that he couldn’t get the pistol to cycle and just wanted to get rid of it for a fraction of what he had invested in it. I gave it a good inspection and could see that most of its parts were of quality. Even if I couldn’t get it to work, I could sell the gun’s parts and still make a decent profit. I brought it home and it sat in the corner of my workshop for years untouched until I learned of Sig Sauer’s SB15 Stablizing Brace. I ordered one immediately, and while I waited for it to be delivered, I stripped my AR pistol down to its individual components. It was then I discovered a cracked gas tube that undoubtedly was the source of the gun’s problems.

I reassembled the gun using a Guntec USA low-profile gas block and a new gas tube. My rebuilt AR pistol has a 10.5-inch barrel, and I installed a free-floating handguard from Guntec USA as well as the company’s cone flash suppressor. I re-assembled the gun’s lower receiver with the new Tac-Con 3MR trigger, a Magpul MOE pistol grip and triggerguard, and a TAPCO single-point sling mount end cap.
Once my SB15 arrived, I slid it into place. To round out my Frankenstein pistol build, I mounted a set of Yankee Hill Machine Quick Deploy sights, an LMT Tactical Latch charging handle and an EOTech holographic sight. On the left side rail I attached an EOTech M6X light and laser.
I fell in love with this new build the first time I shot it. I set out my targets at 50 yards and co-witnessed my EOTech and iron sights. My first three-shot sighting group measured less than 0.75 inches with generic ball ammo. It didn’t surprise me that my build possessed this type of accuracy. What surprised me was that I was able to shoot so effectively with the SB15 brace. The other thing I was pleasantly surprised by was the crispness of the Tac-Con 3MR.
