GG&G MOSSBERG 590 Flashlight Mount

This mount fits perfectly on my 590 retro and its built tough. Easy to install, just screw off the magazine tube cap off and place the light mount.

Was able to add an Olight flashlight on the rail. Looks and works great.

I’m confused. I have a Mossberg 500. The mount GG&G has advertised for the 500 does not fit, not even close!! This one fits like a glove! 4 stars for false advertising?

Works exactly as advertised. Fits my Mossberg shockwave superbly. Nothing negative to report. 5/5

great product, use it on my mossberg 590 shockwave

Freaking awesome

I mounted this on my Shockwave 590 so I can attach my Inforce WML light and have it up front and out of the way. The quality is pretty good and the fit was almost great but, there was one little bitty issue. I have a tactical picatinny rail forend and it was bumping into the GG&G light mount until I slightly bent it outward. I had to push it out maybe 2-3 millimeters so I can rack the shotgun. Not perfect but a minor obstacle. Overall I like it and now my rail light is out of my way but still able to activate the light with my left thumb.

Nice quality. But... there is a ball bearing in a detent that is made to only mount in one direction. On my Mossberg 590, the magazine tube is long enough that it actually put the weapon light past the end of the barrel if on my not dominant hand side. I wanted the light on the left side so I could turn it on with my lefthand thumb. In order to have the light on the left side and not sticking out past the barrel, I had to flip the mount. This would be easy enough if the ball bearing in the detent was reversible- but it is not. I had to punch the ball bearing out and rely on increased friction of tightening the magazine tube cap to hold the mount on. Normally lightly tightening the mag tube nut/cap would hold this in place- if it had the detent/ball bearing on the opposite side of the ribbed cap. Because I had to modify the mount and it was not a seamless installation, I give it 3 stars.
