2 Pcs Rifle Scope 30mm 25.4mm 1 inch Tactical Light Flashlight Mounts Scope Ring Adaptor with Picatinny Weaver Universal Rail

This Picatinny rail adapter is 30mm with a 25.4mm plastic insert filler to fit most standard 1 inch or 30mm rifle scopes. I used one on a scope to allow me to mount a reflex sight above or sideways on the left side of the scope. I installed one on the front end of my 12-gauge pump shotgun tube magazine for mounting a green laser. My pump grip stops about 3 inches short of the barrel clamp so on my shotgun there was plenty of room though it would not easily provide mounting for a reflex sight as the configuration is not reasonable for that. I did need to remove and reinstall the barrel to get the strap between the barrel and the magazine tube. I just removed the threaded cap at the end of the magazine tube, slid the barrel off, attached the picatinny rail adaptor, and reinstalled the barrel. Took about 5 minutes with the only tool required being the hex wrench that came with the Picatinny rail adapter.Your magazine tube may be a different size. Mine is about 25.6mm and fit without modification of the plastic spacer. I will probably buy again.

Product is of good quality, fits well and I am satisfied with my purchase.

I purchased this for so I could mount a light on my BIKE and the diameter was a tiny bit big. But 2 small strips of mounting tape on the inside diameter and it fit like a glove and NO SCRATCHS. AND I have an extra , just in case I get another ... bike

MOUTED ON MY 12 GA MOSSBERG MAGAZINE TUBE USING INCLUDED SPACERS . IT'S VERY TIGHT , NO SLIP . GREAT FIT .

Perfect fit for my Shotgun

Attached without issues to both 30mm and 1" tubes with the provided inserts.

Purchased it for one of my relatives. According to them great value for money

Bought these for my 10/22 takedown so I wouldn't have any problems keeping zero with my green dot. Had to do some custom fitting but they work great.
