  1. Really like the way you did this build. Very clear and concise. I'm going to put together a 8.5 inch pistol. Upper already complete and stripped lower, all from Palmetto State Armory. Just ordered pin punches, hammer, etc. Your video will really help with the build. Thanks.

  2. For someone new to this I suggest placing some tape on the lower while driving in the roll pin for the bolt catch…makes it not as easy to scratch. I know you Pro builders and do this easily but I have seen so many new builder slip and scratch that area.

  3. RE: Mag release install. You can install the roll pin with a pair of goose neck pliers and it is super easy. Just tape the jaws up, and put some tape on the tabs where the roll pin goes to protect the finish. Start the roll pin and get it to just protrude into the gap using the pliers. Line up your release lever on the pin, then squeeze the pin through with the pliers.
    Easy peezie, roll pin squeezie!

    Great video! Love the custom paint!

  4. I've done several builds with Anderson products. All very great!! Question: Why did you use a 10 1/2'' barrel and not a 7 1/2''? It would've been lighter. And why did you put a, what looks like a butt stock on it, which I know it's not a butt stock? Just use a buffer tube. My pistol weighs 4lbs. 12oz. The AR rifle is the one I used the Anderson lower & upper on. On all my builds, I like a contrast of stainless barrels and muzzle brakes, and gas blocks & gas tubes. The reason my pistol is so light is I used an F-1 Firearms Skeletonized upper, & a Ghost Firearms Skeletonized lower. I also have a Mega Arms Skeletonized trigger group and hammer. The handguard is 7'' by Fortis. I also have a X-Products Skeletonized 50 round drum magazine. Which looks very bad ass on the pistol!! Wish I could send some pictures of it to you. Anyway, very good video, and very detailed assembly. Thanks Jay

  5. this was exactly what i needed to see debating on next gun purchase building or buying an AR pistol think I'm gonna build the lower and buy the upper complete nice one dude thanks
