80% Polymer Drama and JMT’s New Lower


Get your own James Madison Tactical 80% lower kit for under a hundred bucks. Jig included.

Many of you who are avid gun owners have been following the recent raids by the ATF in California on ARES Armor and EP Armory. EP Armory is the manufacturer of an 80% Polymer lower receiver that was sold through firearms dealer ARES Armor. The ATF is contending that the 80% Polymer lowers started life out as 100% finished and then was back filled. You can follow more information at http://www.eparmory.com/Current-News-s/1845.htm and http://aresarmor.com/store/NewsArticle/Letter-to-ATF-Director

Another player in the 80% polymer game is James Madison Tactical (JMT) based out of Richland, Washington. What sets JMT apart from the others is that their kit, which costs under $100 bucks includes the jig needed to finish the lower. A truly amazing deal considering all that is included.

In speaking with the brass at JMT, they have not heard from the ATF at this point and don’t plan to anytime soon, but if the time comes and the ATF fixes their sights on JMT, these lowers are going to be gone.

JMT recently updated their product offering by releasing their popular lower in dark earth and OD green. Both colors are a near match to Magpul’s colors and as you can see in the photos, the colors look awesome.

Currently Rainier Arms is a stocking dealer for JMT and they have stock on all three colors, black, FDE and OD.

If you have never completed an 80% lower, JMT has made it easy by producing a complete how-to video series.

  1. Would we be remiss to expect the good folks offering these kits to eliminate the customer data as soon as shipping/payment occurs ?
    Unless anyone missed the Ares/EP flap it revolved around the insistence by BATFE that the customer’s information be surrendered and the retailer’s(and Ares Armor belief anyway) reluctance to turn over that delicate data to be used in an ad-hoc firearms registry by BATFE.

  2. Hi Jody, James Madison Tactical has now received our response letter.

    It is urged that before ordering any 80% lower receiver that you verify the manufacturer has been approved by the ATF/ FTB and meets this compliance. The manufacturer should be able to furnish you with a copy of their approval letter.

    As of August 21, 2014, James Madison Tactical LLC has received this ever so important determination letter from the ATF/FTB that our JMT 80 lower receiver is not classified as a firearm as defined in 18 U.S.C. 921(a)(3). The examination states that manufacturing operations have not been performed in the fire control section of the receiver blank and that the casting has not reached a point in the manufacturing process to be classified as a firearm.
