Description
JMT’s beefed up and redesigned Gen 2 Polymer 80% Lower is now available in .308 and 7.62 NATO. Build an AR-10 clone or accurate bench rifle and enjoy critical weight savings without sacrificing reliability.
Upgraded Polymer
This receiver blank was massively reinforced, tested, and re-tested by JMT to guarantee it handles any .30-cal loads you slam through the muzzle. JMT took their existing polymer fiber and upgraded it to be tough, stiffer, and harder, ensuring your receiver is utterly reliable.
LR-308 / Mil-Spec Compatibility
Its 100% mil-spec construction accepts all .308 DPMS components, mil-spec buffer tubes, standard .308 LPKs, and your favorite Magpul magazines. The mag well’s even cut to match! This receiver includes the 80% jig required for drilling the LPK pin holes and trigger cavity, making it a great value for completing your LR-308 or AR-10 clone on a budget.
Upgraded Features:
- Extended upper fire control box sections.
- Upper left magazine well box section.
- Webbed magazine wells match Magpul mags.
- Extended bolt release roll pin posts.
