Who wants to pay a big chunk of cash for a jig when they're only planning on milling and drilling just a few lowers? What, you're not a fan either of forking over your hard-earned dough for a complicated jig system that you'll only use a few times before it starts collecting dust in your garage? There should really be some sort of solution for that...like a support group. Or this jig from Polymer80.

The Polymer80 RJ556U AR-15/AR9 Universal Jig was designed with exactly you in mind. Everybody knows Polymer80 has a great line of polymer lowers and accompanying jigs.But guess what? This jig works on both polymer AND aluminum lowers. As long as your lower has all the usual mil-spec dimensions, you can use it to mill them out too. The Polymer80 AR-15/AR9 Universal Jig is designed with a super rigid long-fiber nylon composite, which will allow you to utilize the 80% lower jig up to 3 times. And it's way easier on your wallet too. Let us be your support group, and get to milling!

The Polymer80 P80RJ556U AR15/AR9 Universal Jig includes:

  • 2 sided jig
  • 3 trigger guides
  • 9mm HSS end mill
  • 5/16ths drill bit
  • 3/8ths drill bit
  • 5/32nd drill bit

Extremely expensive or high-end tools are not required to use this jig to finish your lower. All of the tools mentioned below can be utilized for other popular Polymer80 receiver projects, including .308 80 lower receivers and 80% Glock® compatible pistol frames, so it’s easy to justify the expense!
