MonstrumHypergrip Cantilever Scope Mount with Quick Release

Great idea implemented well and affordably without sacrificing quality. I have Mostrom range use products: scope lens covers, scope overall covers , scope mounts, and rings too. The cantilever Secure/fix- Release mounts are great. The Cantilever idea IS GREAT . Both ideas implemented together allows scope eye-relief adjustment (back and forward). The Clips to the rail allow transfer between rifles if Needed, quickly -also to get optimal scope for that rifle shooting distance( magnification and such ). GREAT product all affordable price.

Solid and well made mounts. Nice locking mechanisms. Very nice finish on them too. Never got the chance to use them though. The rings did not fit between the objective lenses and eyepieces on the scopes. The tube is 30mm, but the objectives are 34mm. It would have been nice to have the inside measurements between the rings AND the outside measurements to check against the scope. Also, the rings themselves are about 3/4” wide (each ring). Had to return, but I really liked them!

Very good and very sturdy. Easy to adjust.

Not very easy to disengage, but it works fine...Haven't tested how well it holds zero yet

These QD mounts are currently the best bang your buck. Have no issues holding up to 556 and other similar loads. Have not yet fully tested on 308s but expect these to do well (for what they are).

the quick release levers have much better lock system. it's mounted on a 50 big. the previous unit I had would pop loose so hope this one stays tight. it looks well made and beefier latches but they are easer to release as release buttons are bigger. I would recommend.

I read the reviews others had posted regarding this mount and noticed people had mentioned that the mount sat offset on many different picatinny rails and even provided pictures to this effect. I decided to purchase this mount to find out for myself why this was occurring. I figured I could always return it if there wasn't a simple solution to the problem. Upon receiving the mount, along with a Monstrum 20 MOA Medium Riser, I attempted to fit the mount onto the riser and sure enough the mount sits offset on the riser. In addition to being offset it is also slightly raised on the side with the locking levers. Upon examination of the mount in an attempt to determine the cause for these issues, I discovered that the noses of the securement nuts protrude too far through the base of the mount and interfere with the dovetails and their ability to match up and seat together. These nuts would either have to be shortened by about 3/32" or a 3/32" hardened flat washer would need to be place on the nuts prior too the nuts being placed in the mount's base. I also noticed that the dovetail on the side of the nuts is very thin and provides a small grip for the matching dovetail on that side. I do not want to modify the mount thereby excluding the MONSTRUM LIFETIME WARRANTY, so I called MONSTRUM and left a detailed voicemail message describing the situation to which I have heard no reply. So for the rest of the mount, it is very heavy duty and I believe it might stand up to recoil of the 50BMG I intended to mount it on. One other issue is that the upper ring halves do not match up correctly with the lower halves. This may be corrected with a scope lapping tool but I would have done this procedure regardless of any brand mount in order to ensure accuracy and to protect my scope tube from any denting or creasing. on it's tube. If I do not hear back from MONSTRUM prior to the RETURN WINDOW closing, I will return the mount and search for a better made unit.

The item was as I expected, well made, easy attachment/ detachment.
