Updates:

7-20-26 - I’ve updated the barrel vice as it was too shallow to hold an oring.

8-28-26 - I’ve added a drum spring version of the internal mag. The base and follower will need to go with it.

9-7-26 I’ve added 2 new back ends that allow bigger springs. I’ve had good results using k25 and k26 springs.
