A jig to cut a sear sleeve from a common 1/4"ID x 3/8"OD x 1/2" length solid machine bushing to insert into the frame of the Big-Point. I found these bushings at my local small town hardware store at low cost. I cut the slots out with a grinding wheel on a Dremel. It may also fit the Lo-Point, but I don't have one to try it on. Prevents the sear from binding in the plastic due to the tremendous side loading of the trigger system. You can drill your frame with a 3/8" bit and install it, Or please feel free to add this cavity directly to your models before printing. Also, you can use this as a test print for sizing before you print the whole frame. Now uploaded in .stl format
