SPECS: Black Acetyl Delrin. Weight 3 Oz. +/-
CRITICAL NOTE PLEASE READ
If your lower has an additional coating on it (meaning over the hard coat anodization they all begin with), you will need some additional installation information BEFORE INSTALLATION.

Worked great on my CMMG Guard. Much faster reloads.
Excellent Fit
This Magwell fit perfectly, no movement at all. The screw really isn't that hard to install, I put a small notch on the end of a popsicle stick to make room for the allen wrench, and put a little downward pressure, went right in.
Makes mag changes easy!
Super fast shipping! I needed this for a match that had a lot of mandatory reloads...it’s worked perfect and arrived quickly. Thank you!
Techwell PCC Magwell
This magwell required considerable trimming with Dremel tool before it would side far enough to the rear to allow installation of the retaining screw (which is tricky). Once I got it installed it worked fine, although the alignment with the magazine opening on the CMMG 9mm Resolute carbine could be better.
Fast mag changes
Very nice mag well. Fit great and easy to install.
