Solid magwell but - Toni System Magwell for Arex Rex Zero 1

This is a well shaped and machined magwell. The one caveat is the tolerances may not line up perfectly with your gun, even with the included adjustment/timing screw. It did not fit perfectly with my ZERO 1T, and required a little gunsmithing which ruined the finish. It also doesn't work with the factory extended +2 basepads. You'll need to get Toni Systems' own basepads (good luck finding them in stock the US). Other than that, awesome product.
