Question: Will i have to remove the vented rib on top of the barrel before installing this or will it fit under neath of it?
Document: I have this mounted on my M590A1 and the fit is extremely secure with the provided screws. Note that, at least for me, dis assembly of the barrel is required as the mount has a middle piece that won't simply &#34;slide in between.&#34;In terms of the build and quality, zero complaints there. The top piece does not obstruct my sight picture at all and the side rails also include swivel mounts.High quality mount!
I just undid the forward magazine screw, slipped the center piece of the mount in-between the barrel and magazine, then re-attached the magazine to the forward screw under the barrel.The mount is definitely fitted/sized as in the picture: the three rails are on the side and the bottom. However, I see no reason why it wouldn't fit if you wanted the bottom rail to be on top: you would just likely use the longer screws that are included with the mount's hex wrench.
Im very impressed. They came with an assortment of machine screws of different length with allen heads, and the wrenches ! I installed two of these on Remington 870's with different barrel lengths and different brands and length of extended magazines. No problem at all installing them.
Got this in the mail this morning and attached it right away to my Maverick 88. It was a cinch to put on, and fits tightly.I was a bit confused at first whether to use the long screws or short screws (8 of each included) because I noticed that the screws on top used the same threaded hole as the ones on the bottom, and two long screws wouldn't fit in the same one on each end without hitting each other and leaving a part loose.
I bought this for a 870 with a 7 round ATI fluted magazine extension. Does not fit between the barrel and tube. its to thick.
This was the perfect mount for the Mossberg Model 590. Just what I wanted to be able to mount a light and/or laser. No problem in mounting. All setup in about 5 minutes after removing the barrel. Solid fit.
So, despite clearly saying this will fit 'all' 12g Mossberg shotguns, this does NOT. I've tried every configuration and it's a no go. If you have a staggered barrel/mag tube, keep shopping!
that the long screws hold the bottom rail on, short ones hold the top cover on.
fast shipping, arrived a week earlier tht forecast. good quality, and fit. lighter than  i thought. highly recommended
I love this fit my gun great and it is very secure I love thats its metal most stuff is plastic and it was a good price
