Things I liked: This mount is made specifically for the Hammerli 850 rifle, but when you can use a one piece conversion mount from a 3/8" or 11mm dovetail to weaver rail, this unit provides the lowest profile to allow you to maintain a good check-weld with the comb of the stock while viewing through the scope. The fit varies with the dovetail rail it is installed on. On some it will slide in place with just a little resistance and then can be clamped in place with the set screws. On others it is a tight fit requiring some lube to assist its installation by being bumped along with a nylon-headed hammer. I have used this mount for several rifles including the Beeman R-9 which was a very tight fit. Nonetheless, it was able to be bumped along without galling or other damage. I was able to place it where its rearmost clamping screw hole aligned with the recoil lug recess of the receiver to provide for the installation of a recoil lug. It has not budged.
Things I would have changed: I would like to see someone manufacture these as a two-piece unit for applications where the one-piece unit can not be used due to the fact it would block access to the loading port of a bolt-action. The low profile, tight tolerances and hidden top mount clamping screws of this mount give it the appearance of a rail which has been machined integral with the receiver.
What others should know: The dovetail rail you are seeking to convert must have at least one "open" end. By that I mean it must be cut fully through the end of the receiver and not terminate short of the end preventing this mount from being slid on. This mount must be slid in place along the dovetail and will not fit over the dovetail cut to be clamped in place from one side. Until someone manufactures a unit such as this with its minimum height profile as a two-piece mount, it can not be used for any application the will block access to the loading port. If you are skilled to do so, it can be halved, redressed and refinished to fit applications such as the Crosman steel receivers (22xx and Discovery) or the Benjamin Marauder rifle and pistol receivers. There are other conversion units out there, but none I know of that gives the appearance of a Weaver rail that is machined integral with the receiver. All have side clamping screws. This unit clamps in place from the top.
Things I liked: A nice low profile option for converting 11mm dovetail to Weaver mounts. Finely machined to specifications.
Things I would have changed: The four hex screws and supplied hex wrench that are used to secure the mount are one size too small in my opinion. I was hesitant to torque too much while tightening the lock down screws as I felt either the wrench would bend/break or that I would strip the hex screw. You really have to pay attention while using the wrench and double check that it's completely inserted to the bottom of the hex screw or you may have issues as I believe I did with one of the four. Also as described in one of the other reviews, I totally agree that a strategically located standard of the industry stop pin assembly would greatly enhance this product for break barrel rifles that produce harsh recoils.
What others should know: I mounted my Hammerli on a Beeman R9. I also found it necessary to tap it into position using a proper hammer as not to damage the mount. I found it very, very snug and was initially concerned whether I was going to be able to get it completely mounted into position without damaging either the mount or the rifle. Once I did, I felt it so snug and secure that I thought with tightening the hex screws this thing would never budge. Well, after a couple hundred shots or so later, it did slightly, approximately 1/32 - 1/16 inch. I was shocked as I felt this thing was so welded I'd never have a concern. I've now readjcusted and remounted it back into its original position and will monitor any creepage. I may revert to carefully drilling a stop pin hole that will fit the R9 factory pin stop. I primarily chose this mount vs dovetail with pin stop as I like the low profile and wanted to use and maximize the Weaver mounts supplied with my UTG Accushot Swat Scope.
Things I liked: I like that this Hammerli 850 AirMagnum 11mm-to-Weaver scope rail is very simple and versatile. I have installed this rail on both my Hammerli 850 and my Crosman 1077W rifles. This rail works well converting the 11mm dovetail to the Weaver mount without adding much height. The set screws lock the rail down on the dovetail very securely, and the rail is very stable once the set screws are screwed in.
Things I would have changed: Nothing.
What others should know: The length of the 11mm-to-Weaver rail is 6 inches which matches the length of the dovetail on the Hammerli 850 AirMagnum rifle. However, the Crosman 1077 / 1077W dovetails are only 4 inches long. This rail can be used on the Crosman 1077 / 1077W because the rail's set screws are just less than 4 inches apart. Once the rail is slid onto the Crosman 11mm dovetail both set screws can be tightened against the dovetail with about 1 inch of rail extending past both ends of the dovetail. The initial fit of the rail on the Crosman dovetail was quite snug, and I had to use a soft mallet to tap the rail to slide it onto the dovetail. I'm glad the rail had that extra inch past the back end of the dovetail because I needed to mount a ring on that part of the rail in order to position the UTG 4x32 AO scope at the proper eye relief distance. Using only the dovetail and dovetail scope rings, it may not have been possible to adjust this particular UTG scope to the proper eye relief distance.
Will this fit the 11mm dovetail on a Benjamin Titan GP, how much is the bottom of the rail curved?
will thit fit on the rws 350 magnum with the t06 trigger
The length of the 11mm-to-Weaver rail is 6 inches which matches the length of the dovetail on the Hammerli 850
Does the rail fit curved dove tail such as Grunig & Elmier st200,ft300?
