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.
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: We cannot ship this part internationally.

Great product works very well on my GMR15
I didn't know what I was missing out on until I tried it. The magwell works very well in guiding the magazine in at the right angle.
Recently purchased JP Fattie Magwell for my GMR-15. Fit and finish in my book was 10 stars not 5. I have been a machinist for 51 years and have had my own business for 34 of those years. I know fit and finish very well. It doesn't get any better than this. I also have 2 of TF's Goliath mag extensions, same for them and they function flawlessly. One other thing service was great. Got everything in 2 days.
Excellent product, fit was exact and easy to install, I would highly recommend.
Excellent Product, Great Design, Fast Shipping & Awesome Customer Service. Highly Recommended !!
