Taylor Freelance JP Enterprises GMR-15 Fattie Magwell

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. Their magwells are cut so that if you insert the magazine directly into the well, it will slide into place and lock. Their 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.)
