Why This Jig Kit Wins
Having milled dozens of frames on our Spring TX CNC floor, I’ll take Polymer80’s steel-lined jig over bargain bins any day. The 3mm drill guides don’t wallow out after three builds like Chinese clones. At half the cost of “professional” systems, it handles everything from weekend P80 projects to FFL production work.
