Question: what exactly does this product fit on to? Some say it does fit a 3/8 dovetail based rifle, and some say it does not.  The product description is useless.  Lets clear this up once and for all- what does this adapter fit ON to?  We know it is a weaver on top, but again what does it fit ON to?
Document: This adapter is exactly what I've been looking for to fit my Sig Trailside .22LR pistol. Contrary to you'll read or be told, the Trailside's frame dovetail is -NOT- 3/8". Thank you, UTG!! !
UTG 11mm Adaptor does not fit .22 rifles also I bought a 3/8" adaptor and it also does not fit. I have Remington, Winchester and J C Higgens .22 rifles and they dont fit any of them.The adapters look to be a good product,  but I doen't know what it fits.
I ordered this adapter to be able to mount a Weaver or Picatinny type optical sight on my Crosman 3576W. This revolver has a 3/8'' (9.5mm) dovetail mounting rail on the top of the barrel. The adapter fit the gun perfectly.Unfortunately it will only work if the mounting dovetail is relatively flat.
Exactly What I needed, exactly When I needed it. It may be way over the top, but Amazon may have saved the day, at least at the range. I needed to mount a red dot scope (Weaver mount) to a Remington 597 with a dovetail mount. I wanted to easily change from the regular iron sights to the red dot for my Nephew who will be learning proper gun safety and how to shoot safely, if I have anything to say about it.
This is a very quality made item for such a low price. I have had it on 3 guns till I finally decided it would stay on my Marlin 60, a .22 caliber rifle. It worked on my pellet gun, my .22 S&W 15-22, and now on my Marlin. It sits on the built in rifle scope grooves, and then lets me add any scope made to fit a picatinny/weaver rail. Could not be happier with this product.
This adapter works well. I bought a Simmons Red-Dot Scope for my .22 riflewithout thinking about the mount. The scope had a Weaver mount, and thisadapted it to my 3/8" dovetail. It only raised the scope 5/8" or so.
Solid and very sturdy. Quality product for converting your 3/8 dovetail rail to picatinny/weaver rail. Would buy again in a heartbeat. Cant beat the price.
This little rail adapter converts the groove for 3/8" scope rings to a full-sized picatinny/weaver rail. If you are going to mount a red-dot sight or a holo sight on a rifle with the 3/8" groove this is the least expensive and most practical route.
used this to sporterize a mosin nagant--drive out 2 pins and remove the military rear sight--this exposes a 3/8&#34; dovetail on the rifle-- clamp this puppy on -red locktite and use the old sights pins to further immobilize it--use weaver rings on a long eye relief scope--real solid
I bought this item to replace the 3/8 dovetail mount on my Mossberg semi-auto .22 rifle. There are two reasons for this. Reason 1 is because whenever I put my scope on the dovetail mount it was on at a slightly different angle, which affected the accuracy of the rifle substantially at long ranges. The second reason is because there are more accessories that are compatible for weaver rail, such as red dot sights and more powerful scopes.
Answer: no
