    Product Description

    At last! A match-quality machined aluminum magwell for the JP Pistol Caliber Carbine! (GMR-15).

    The TF Fattie both offers a huge loading "target" and helps the shooter to know what ANGLE to insert the magazine. The factory AR magwell (on all ARs, including PCCs) are cut at angles that look good, but don't actually help the shooter. Our magwells are cut so that if you insert the magazine directly into the well, it will slide into place and lock.

    Our new FoxLock system grabs the inside of the magwell for exceptional strength and security. You won't knock this magwell loose! When it's time to reload in a hurry, you need every advantage you can get! Produced in partnership with Techwell USA.

    Weight: 2.95 ounces
    Material: Aluminum
    Color: Cerakoted Gold

    NOTE: Also works on AVG lowers, can be modified to fit Rainier Arms lowers, but does not fit the JP GMR-13. (The magwell fits, but the FoxLock doesn't.) 

    NOTE: Due to state department restrictions we cannot ship this part internationally.

      Jp fattie magwell

      Posted by Mark Stamper on Sep 29th 2021

      This is a great product! But what else would you come to expect from Robin! The fit to the lower looks like it is all one piece. There is no extra fitting to do. The installation is as easy as it can get. One screw and one small bracket. Even the bracket fits very flush to the lower. I prefer this to tech wells unit.

      JP Fattie Magwell

      I love the look and function of this mag well. I have wanted one for a while. The only reason I gave it 4 stars was the fit. My GMR-15 is pushing 2 years old. That may be the problem, not sure. The magwell just had a slight gap all around and rattled a small amount. I shimmed it with some thin Rubber strips. No rattling now. My buddy has a brand new GMR-15 and he got one of these as well. No rattling on his.

      With the expanding popularity of mandatory mag changes in USPSA stages the fatty mag well is a great addition to the JP platform. The construction is top notch the attachment is very secure and makes mag changes very fast.
