300 AAC Blackout case cutting jig
This hardcoat type III anodized jig quickly and rapidly trims 5.56mm and .223 cases to the length needed for 300 blackout. Mount it in any of the inexpensive 2" saw from Harbor Freight or Amazon with the included hardware and start making your own blackout brass. Just slide the full length case in from the left until it snaps in place. Trim. Then using the next full length case push the cut case out slightly. The cut case ejects under spring tension and the next case to be cut snaps into place.
There are poor copies of our designs for sale on the internet. These cheap jigs jam and scratch cases. They are not ours!
