This is an amazing .22LR beltfed upper that mounts on any AR lower (including a registered [and yes, legal] full auto lower). Watch it run in action:
Now I’ll be honest, this run we had was one of the best ever. Usually it has a few more hiccups than that. But we ended up getting really lucky that day of filming. For instance, when we shot this following video with Firebird Targets, we just couldn’t seem to get it to run:
The design is from Lakeside Machine, and it is out of production. It was called the “Razorback”. In effect, it is a mini-1919 that is adaptable onto a standard (or full auto) AR lower. Back in the day, they were only $800! Now, if you can find a used one, expect to pay at least $3,000.
It is fed by a hand loaded cloth belt. These belts come in lengths of 50, 100, 200, and 500. The Razorback really seems to like CCI Blazer ammunition. We always sprayed the cartridges with silicon lubricant before the tedious loading onto the belt to help with reliability.
What was also not mentioned in the video is what happens to the ejected brass. They fall out the bottom of the magazine well. However we have a “catcher” inserted in the magazine well that holds up to 200 brass as well as provides a place for the belt holder to mount.
