Danny Elliott's Review of Black River Manufacturing Benelli M4 Bolt Release

Installed this on my M4 last night, along with the regular sized mag tube from BRM. Install wasn't hard but when I went to load up the shotty it causes the ejection switch to randomly eject a shell. The faceplate is secured to the bolt release with a tiny little screw and there appears to be alignment keys on the faceplate but there is no corresponding groves on the bolt release so it just wobbles around.
