10mm Auto 30 round Glock magazine in a Spartan AR. Part 2

This video is similar to my Part 1 video where I used a SGM tactical 26 round 45 ACP magazine converted to 10mm in my Glock 40. In this video I use the same converted SGM magazine in a 10mm AR that I built with a Spartan upper/lower receiver set. The barrel and internals are Kaw Valley Precision. I’m shooting S&B 180 grain 10mm ammunition.

  1. Thanks for the video. I just built a 10mm AR and am having the same feeding problems.

    Looking around on YouTube before I started grinding on it, I found something interesting under:
    "[Firearm] Quarter Circle 10 Glock Large Frame Build Update"

    That gentleman, posting under "The GBB Archives" had the same problem and tried a few things. The last thing he tried was a new extractor. The people who made his bolt carrier group noticed he had an old model and sent him a new one with an "s" shaped claw on the extractor. Nope, I don't have that kind of bolt carrier group, but I will sure be looking into doing this type of modification at home. .

  2. Hey there, I just built one my self, haven't shot it yet but I can tell it not going to feed well. Please shoot me an email at sburdinsky83@gmail.com so I can pick your brain on getting my 10mm running smoothly.

    Once you do shoot me an email please remove this comment please and thanks.

    Sam
