Dove Tail

-they are made from same factory for crosman and quality control is not good.-holes drilled to close to edge,misaligned scope caps, front and rear rings not level when mounted on leveled rifle.-You have to order a fewpairs in order to get one good useable one. -When you get a good one they are are okay and design for crosman airrifles, medium recoil, for .177 , 800 fps and under.-not for magum, even with blue loctite oneverthing. Rings base mounting screws is only 3 mm dia. vs leapers 4mm, for same mount.

thank you perfect

Fitting to the dovetail on an old Crosman SSP 250 pistol proved to be challenging. The clamps are made for a flatter top barrel, and the SSP 250 is rounded. I did get them mounted but I would not want them on anything beyond a CO2 powered gun as the recoil of springers and nitro piston rifles would bounce them right off. I think more recent guns from Crosman may have the dovetail milled differently so that they would work on the newer guns. They were tall enough so I could mount a 3x9x40 AO scope which needed the extra height because of the front adjustable objective of the 40mm front. All in all they did the job and they are secure on the SSP 250, so just 1 star off for the frustration of getting them to fit on a rounded barrel top.

These are very decent scope mounting rings, especially considering the low price. They seem well made and hold my scope securely. However, they were difficult to setup properly on my 3/8 inch scope rail. I had to fiddle a lot with the adjustable dovetails to get the rings straight and tight. Hence a 4 instead of a 5 star rating.The first package I received was missing the hex wrench so I requested a replacement. The replacement package was complete.

Works on an air gun would you expect it to do

Used to mount a pair of big 50MM Sniper scopes on my 22 Mag and .25 Benjamin Marauder, allen screws vice the old straight slot screwdriver fasteners, tightens nice and even, does not distort the tube and hamper the parallax adjustment in the scope.

So far so good. The taper needs to be sharper to fit the dove tail of the air rifle better but I'm not affraid to tighten this stuff down. Don't use any other Allen wrenches than the little one they send and you will be less appt to over tighten and strip threads.

Well made just what I was looking for!Ken Carlson

They do the job work great on my UTG bug buster scope for my Benjamin Discovery. Scope is well secured and they haven't come loose yet I have shot the heck out of my rifle and no slack. Would buy again if needed to.

product was as described, no issues with shipping, overall, pleased with purchase

Worked great on my Marauders 25 with 50mm Bushnell scope

I actually used these on a Henry .22 Lever action and it works great. For the price, I think the quality is fine.

They worked just as well as other costing 3X more. Would highly recommend these to anyone.

Complete junk. When mounting lowers it became immediately obvious that one or both won't line up to barrel. They would bend scope tube, ruining scope if completely installed. Just resting scope in the tube lowers rotates the scope more than five degrees off axis.

Perfect!!! Exactly what I needed to mount a large scope on a small rifle.
