NEW! G17/G19 FMDA Front Rail Jigs. Build your own Ave Rails with these simple jigs. Improved method from PY2A Jigs involving 1 less cut to worry about. Dont to forget to share these with your Canadian friends. Hopefully a new Government will help us import again soon without the fear of being raided. As like the other jigs this also uses a 1" block of aluminum or steel.
