GOTCIAL Shotgun 12Ga Barrel Clamp W/Built-in QD Forward Sling Swivel Socket, 3-Slot Picatinny Rail Mount (1.25 in QD Sling Swivel and 2 PCS 4x6 mm Gasket Silicone Elastomer Included)

Works well, well built dose what it says and fits nicely with no movement

This worked well on my Girsan MC312 with extended magazine. The rails are nice.

It fit my Mossberg 88

Nice clamp. Had a small burr on it- reason for 4 stars instead of five. Not a problem-filed the burr off in a couple of swipes. Check the number of slots required by the item you’re mounting. The light I bought requires at 5 slot in the pic rail. No big deal, I’ll find a light that will work for this rail. The rail could be modified.

My husband uses this on his 12-gauge, and it’s been a solid addition to his setup. It holds tight without shifting, even after repeated use, and the install was pretty straightforward. The quick-detach sling mount is super convenient, making it easy to swap slings or adjust on the fly. The small Picatinny rail is a nice touch too—it gives him the option to mount a light without adding too much bulk. The included silicone gaskets helped get a snug fit without messing up the barrel finish, which we both appreciated. It feels sturdy and well made, not like some of the cheaper options out there. So far, it’s been holding up great at the range. If you’re looking for something reliable to add a sling or accessory to your shotgun, this does the job well.

I have a Remington 870 with an extended tube and the size difference between the upper and lower clamp didn’t fit well.

Does not work on a Beretta A 305 12 gauge.

Fits great on my Mossberg 940 Pro Tactical. Very stable. Looks good and good price. The 3M rubber liner protects the finish of the barrel. I would like the color to be a little bit more matte, though. Kind of like Magpul products.
