Test firing the MAC10/45's 

It shot perfectly! 100% reliable. I really like the one piece receiver pin that came with the upper. The upper fit perfectly too on my JAWS lower.

@@535tony Oh okay! That's great. I have to get some magazines and what not so that I can go to the range, as well as get ammo

I was actually testing two JAWS Commando Avengers here. One with the MAX10/45 upper and the second was a gun I just built up from a stripped registered lower. It had a FTF top cocking upper with a FTF bolt assembly. I was using the Lage dual magazine release that works with standard or modified Grease Gun Magazines and I was using unmodified keepshooting.com grease gun magazines. I was sure I would have something that needed tweaking but that gun shot perfect too. It was a great day at the range. Next time I need to use my 50 round magazines!

@@535tony HHAHAHA LUCKY! I'm designing a drum magazine right now for the M10 but it's going to take a lot of work and it's going to be 3D Printed.

@@picklerick9578 I got my 50 round grease gun magazines and 50 round Sten magazines in the 90’s. A guy named Craig Wheatley made them by welding two magazines together. They work 100% too.
