Monstrum Lockdown V3 Picatinny Riser Mount with Recoil Stop Base | 5.5 inch Length | 0 or 20 MOA

This riser works great with Tavor X95 paired with Holosun 510C/3X combo to lower 1/3 co-witness with ironsight. Solid build, perfect length.

I’ve bought and returned at least 3 other 1” risers from other sellers because the quality was poor, most looking like they were cast. This Monstrum riser is BY FAR a the best quality product with edges so sharp and straight it looks like the rails were machined. Cant confirm the aluminum grade used, but it is high quality aluminum and hard (trust me, I did slight trimming with a Dremel cutting wheel and a bench sander), and there are lugs underneath that fit perfectly within the pic rail slots. My only concern may be with the bolts as they are not hefty and screw in to the aluminum block (vs other designs with a pressed bolt and nut), so time will tell if they hold up. I used locktite and torqued them to 15 lbs. So far zero has held after several disconnects and connect of my QD Holosun 510c and magnifier.

Good quality riser, torx mounting screws. Good price. Satisfied customer.

If you're familiar at all with Monstrum you already know what to expect. A surprisingly quality product made to an impressive standard for absolute bargain pin prices, but with issues present that make it difficult to recommend without asterisks.Pros:- Sturdy feeling, three screws really does lock it down hard. Not bendable with bare hands even when removed from a rifle.- Occupies almost the full length of a flat top. Long enough to comfortably fit a sight and magnifier.- Lifts well clear of a front sighted gas block- Very light for how much rail it covers- Well aligned with bore axis- Cheap! Hard to overstate how cheap this sucker is for a durable long riserNeutral:- Even low lifts completely clear of iron sights. Even if the length didn't block a rear sight at gas block level, it is clear of 1/3rd cowitness position- Occupies *almost* the full length of a flat top. Short by about one picatinny groove on mine. If put all the way forward, this leaves a lot of a clearance for the charging handle. Too much in my opinion, ymmv.Cons:- No torque spec provided; seems to be made out of aluminum and I was worried about overtightening- No threadlocker included and threadlocker is needed for a mount with screws like this- huge holes on either end are visually unattractive and create a long open section that's irritating to clean were it get dirt or grime in it- Two part assembly is a fiddly to get installed. Screws are not long enough to thread and then place on to rail, both pieces need to be pinched in place and screws threaded.- While visually aligned, I'm not sure how much I would trust that alignment for a more precision rifle with higher magnification. I do not have the proper equipment to measure how well it is actually aligned.- Big and garish Monstrum logo on the side

works

This riser put my optic at the correct height and it came with 2 extra screws in case you lose one

Works great if you need to raise your mount a little bit to get proper sight geometry and cant find any other mount that works. I used it to raise a reflex sight so that I could see the flip-up iron sights through the reflex sight.

Used to correct scope placement more forward for eye relief. Was easy to modify in mill. Very solid mount. 15 inch lbs torque and no movement
