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!
