Monstrum Shrapnel Offset Picatinny Riser Mount with Recoil Stop Base | 8 Slot 3.5 inch

perfect fit, nice material and nice finish. Worked perfect to lift my scope just enough to get over hard sight.

Perfect mount to offset my Eotech and magnifier for NV

I had a problem with a holographic sight mounted on the picatinny rail machined into the receiver of a modern, higher power air rifle where it was too low. I had to roll my head / cheek down to see it and that prevented a proper shoulder mount and shooting position. This spacer has nicely solved the problem as it raised the sight just right, I can now do a proper cheek weld and not have a hunched posture and when I quickly mount the rifle to my shoulder to the dot is centered and I'm on target. The riser is nicely machined, the edges were deburred and it has a good black mat finish. It fit and tightened up well with no rocking then the holosight fit on top well too. Note that I pushed the riser forward in the picatinny slots, there's slop there then also pushed the holosight forward to take up the space there too. Some people might want an exact spec (tight) Picatinny but I don't have a complaint, I move the different pieces in the direction recoil would take them so it can't move any farther then tighten (and I DO use a 1/4" torque wrench to specs so there's no question of over or under tightening!) and if everything else is correct nothing ever moves. If course only an idiot wouldn't check their zero after removing and replacing sights so it was a pleasant surprise that this riser was was machined true enough that I didn't have to change elevation at all and only windage an inch to be back on target at 85 yards. I sight in at 85 yards so I'm 3" high at 50 yards and 3" low at 100 w/ a 36gr slug @ 960FPS muzzle. For small game and varmint hunting this gives a great 'point blank' sighting method and reduces range estimation errors (without the usual practice of having a 50 yard zero and a lot of drop to estimate at 100)

Shipped quick and i got it ahead of time Quality riser good for that extra height

This is significantly cheaper than comparable name brand products. Works well, feels sturdy. Great for plinking, the range, a little hunting here and there. Most likely not suitable for professional use.

I had previously bought a mount exactly like this one, made by Phoking. That mount works but, when looking at it from the end, appears to be barely grabbing onto to receiver rail. Didn't really feel solid and, although it has not come off, has always made me nervous. I was recently in need of another short cantilever riser to mount a prism scope a little further to the rear and found this one. I'm very impressed with the fit, finish, and solid feel of this mount. Instead of just the mounting screws indexing into the receiver rail, this mount has three machined blocks that fit snugly into the receiver rail. The clamping plate is thick and solid, fits very well onto the receiver rail, and is secured by three screws. These attributes combine to give the mount a rock-solid feel that I'm sure I'll never have an issue with. Would expect to pay double for this quality. If it only had about 2 more slots, it would be the perfect offset mount!

Material, machining and quality is decent enough. Main problem I faced is it wasn't fully compatible with the optic I wanted to put on which was the vortex uh1. It's able to be put on but a third of the optic isn't secured to the rail. The brackets on the side that secure it to an existing picatini rail is kinda high and wide to accommodate for certain attachments. But was able to work with a aimpoint comp-m4, and probably wouldve been compatible with my swampfox liberator (aimpoint t2, mirco red dot clone). So be aware not all attachments will be compatible.

Great riser. Gives about a 1/2 inch rise. Well built. Will not break.
