The LR-308 rifle you just built or AR-10 clone doesn’t need to weigh close to 20 pounds. Between that big barrel, variable-zoom optic, bipod, and bench-ready Magpul buttstock, you’re already tipping the scales. To shave the ounces off your rifle's fat ass wherever possible, try out James Madison Tactical’s new lightweight Gen 2 Polymer 80% .308 Lower, this one being in the OD green color.
This DPMS gen 1 compatible receiver blank has been dramatically upgraded to reliably handle the heft and recoil of any .308 or 7.62 NATO loads you send downrange. JMT also put this lower through the gauntlet after upgrading its polymer-fiber material to be tougher, stiffer, and harder, which means it’s truly capable of handling rapid fire, high heat, and high impacts.
This JMT lower receiver is mil-spec and compatible with all DPMS gen 1 LR-308 parts. It’s even cut to match your favorite Magpul mags! Completing this 80% lower is too easy, thanks to the included jig for cutting and drilling your pin holes and fire control group cavity.
- Extended upper fire control box sections.
- Upper left magazine well box section.
- Webbed magazine wells match Magpul mags.
- Extended bolt release roll pin posts.
- New JMT Gen2 logo markings.
