Hawke Sport Optics 1-Pc Elevation Adapter, 3/8" to Weaver Rail

The assembly is sturdy and easy to mount.

The set screws provided to lock things in place should be better quality. The hex end of one of mine was misshapen right out of the package.

It comes with no instructions and no link to them on the Hawke web site. You have to depend on internet reviews and comments for adjustment advice.

Adjustment range

Finer thread on the tilt adjustment screw.

If you can use the one piece UTG drooper mount, do so. Getting everything lined up even with a laser boresighter was lengthy and tedious. Too high, then too low, then high, then low, remove rear ring each time for adjustment screw access. Unfortunately, this early Diana 48 has massive droop on it, the UTG mount didn't get rid of it, couldn't be sighted in even with Burris rings and offset inserts. It remains to be seen if adjustments stay put with the recoil on this beast, it's in .25 caliber. I've used the previous RWS adjustable mounts, none stayed put, one has more screws than this one. Right now it's boresighted, needs actual sighting in. There's 4 clamp screws that not only hold the mount onto the dovetail, they also clamp the center part that tilts. Not sure how well they'll hold given the recoil that the 48 has. On the Diana, the front stop pin hooks right over the end of the sight dovetail on the rifle. Should hold it from sliding.

Well made and adequate.

Quality riser. Very secure mounting capability.

The mount does exactly what I needed-compensate for massive (16" at 25yds, i.e. 64MOA) barrel droop on a Beeman R7. I'd tried using the scope adjustments but the scope shift was unacceptable. Other mounts didn't have the range of compensation I needed. After about 200 shots the scope is still solidly in place and the elevation hasn't changed. It's long enough that I was able to find the best ring spacing for the eye relief my scope requires.

The reason I gave it 4 stars instead of 5 is the design makes changing elevation tedious. You have to remove the scope to get access to the adjusting screw. Fortunately, you can leave the lower rings on unless you have to cover the screw with the rear ring. The mount does not come with instructions so you have to download them as a .pdf file that is available on the product description page. You have to loosen the screws that attach the mount to the rifle so it's possible to loosen them too far and have the mount shift position (there is not stop pin) when you change elevation. The elevating part of the mount doesn't have to be loose to adjust it, it will move if slightly snug. None of these things prevent me from recommending the mount.

DOWNLOAD THE INSTRUCTIONS AND READ THEM! Some of the features of the mount are not obvious. For instance, there is a pin at the front of the mount. It's to be used if your rifle has a flat "ledge" between the receiver and the barrel and acts as a stop pin. If the receiver smoothly transitions to the barrel as mine does, remove the pin, it just pushes out. The elevation screw is NOT a stop pin. Putting it into a stop pin hole will cause it to break. Make sure the elevation screw is contacting the top of the receiver, not dropping into a stop pin hole. The mount is intended to be sighted in at 20 yards. At that distance each complete turn of the elevation screw moves the point of impact 7." Knowing this makes adjusting the mount MUCH easier. Be sure to use the set screw in the end of the mount to lock the elevation screw and press down on the scope before you lock the elevation to make sure it is firmly against the receiver.
Most negative comments were from not reading the instructions.

Well made,sturdy mount.scope hasnt moved yet.

Great mount would buy it again

Easy of use and fit correctly the first time

No scope stop, scope, rings, adapter shift backwards. You have to remove scope+rings to adjust adapter. Remove scope, rings, then loosen set screw, then turn a grub screw, then retighten set screw, remount scope+rings. Repeat, and repeat, and repeat. Took me over an hour to do this, then had everything shift with less than a tin of pellets afterwards. Buy something else, Hawke engineers were asleep at the wheel with this product!

You have to remove scope+rings after every adjustment, then put everything back, torque, and then hope it was all in the same place as before. You install this at the shooting range, not your home, because you have to shoot, then remove scope+rings, reassemble, shoot, remove scope+rings, reassemble, etc., etc. Took me over 1 hour to get to the point where I was close enough to use the turrets.
After less than 500 shots, it shifted. There is no scope stop. DON'T buy this! Worthless. I'm going to use it for a set line sinker next spring!

Quick easy install. Takes most of the elevation adjustment prior to any adjustment at the scope turret, keeping the scope's elevation more closely left at the center of travel, it's most stable point. Get it close with the mount adjustment, then just fine tune the elevation at the scope turret.

make the elevation adjustment screw accessible from the rear rather than the top. A tapered end on the adjuster, fitted where the lock down screw is now, then move the lockdown screw to the side would do it. I had to dismount the scope each time it was adjusted during the sight in process. Not a big deal.

Converts the 11mm dovetail scope mounting on RWS air rifles to weaver/ picatinny rail.

A very well made mount. This gave me more peace of mind than only using the grooves on the rifle.Very solid with adjustment if concerned about recoil. The Weaver rings fit with little fuss for a nice combo.

Instruction sheet, but the nice Lady at PA answered all my questions!

This mount should fit a multitude of grooved receivers.
