James Madison Tactical JMT 308AR Lower Receiver 80%

James Madison Tactical JMT 308 AR 80% Lower Receiver

This is the all new James Madison Tactical .308 80% lower receiver. JMT is constantly evolving with products to deliver the ultimate lowers in the industry. JMT has now engineered the best polymer/composite .308 on the market today unparallel by any other with the same refined cosmetics that you find in our AR-15 composite / polymer lower. We invite you to take a look and compare the new JMT .308 to the competition. After doing so, we are completely confident you will choose JMT.

Key enhancements include:

Extended upper fire control box sections.
Upper left magazine well box section.
Webbed magazine wells L & R side (matched for MagPul) magazines.
Extended bolt release roll pin posts.
New JMT Gen2 logo markings.
DPMS Compliant

The polymer 80% lower receiver for your .308 platform is engineered and manufactured by James Madison Tactical (JMT) in the USA. This is not your average polymer 80 lower, in fact, The JMT 308 AR 80% lower is fully engineered using current finite element structural analysis for reliable, long-term high performance.

JMT 308 AR POLYMER 80 versus ALUMINUM

After much research in polymer .308 lowers, JMT created its own formula of hybrid polymers and fibers with additional reinforcements in high stress areas to bring you the best .308 lower on the market today. All of the JMT polymer 80 lowers are engineered to Mil Spec tolerances and because it is fashioned from extremely durable fiber polymer materials there are no concerns about corrosion as you may find in aluminum .308 lowers.

IN FIELD DURABILITY

JMT uses only the best high quality hybrid polymer/composite materials, advanced engineering, precision manufacturing and stringent quality controls. This way you can trust it not only in the harshest field environments but for personal protection as well.

JMT 308 AR PARTS INTERCHANGEABILITY

The Polymer 80 .308 80% lower is designed specifically to Mil Spec tolerances for a high level of interchangeability with other Mil Spec .308 parts and accessories on the market today. This is achieved through current technology and computer aided manufacturing processes combined with exacting quality control procedures.

PERSONAL DEFENSE AND PROTECTION

How you decide to defend and protect yourself and your family is a personal matter. No one wishes to experience a personal breach of your safety or a home invasion but it does happen. The mission at JMT is to give you the assurance in a product you can trust.

The operations left to be completed to complete your JMT .308 80% lower are as follows: fire control group, trigger pin, hammer pin, trigger slot and the safety selector hole. This is a not an FFL item. This is not a complete receiver and still requires machining to be done.

POF 308AR Stripped Lower Receiver

by Donald Sullivan | May 14, 2015 | AR 308 Receivers | 0 comments

POF 308 AR Stripped Lower Receiver

POF 308 AR Stripped Lower Receiver, semi-auto lower receiver is fully machined from U.S.-sourced 7075 T6 aluminum billet for superb strength and precise dimensions. Extra metal in the right places gives a big payoff in added support and rigidity with minimal extra weight. Available in AR-15 and AR-style .308 sizes, both models accept mil-spec and aftermarket components, so you can select the upper, trigger group, pistol grip, receiver extension, and buttstock that best serve your needs—the perfect foundation for a custom tactical rifle.

Integral, oversized trigger guard machined as part of the receiver further enhances structural rigidity and provides plenty of clearance for trigger finger when wearing gloves. Radiused inside and outside edges protect finger from cuts and scrapes when mounting weapon quickly or during extended fire. Flared magwell with smoothly radiused inside corners helps ensure fast reloads, without fumbling, when seconds count. Cut for ambidextrous bolt release to allow strong- or weak-hand operation; right-side button included with receiver. Laser etched, international “fire” and “safe” symbols give the operator instant, intuitive feedback on the weapon’s safety status in high-stress situations. Mil-spec hardcoat anodized for additional surface strength and corrosion resistance. P-415 is available with a durable, low-friction black Teflon® finish or a tough, gray NP3 electroless nickel/Teflon outer coating that’s highly resistant to surface wear. NP3 is exceptionally thin, hard (Rc 48-51), and self-lubricating, so it prolongs weapon life by minimizing wear fouling buildup. P-308 is available with NP3 finish only. All heat-treatment, plating, coatings applied by U.S.-owned and operated contractors. Click here for purchasing info.

Note: A POF lower does not perfectly mate with a DPMS 308AR pattern gun. The pins are a different size and the upper itself might need some minor machining
