Monstrum Cyborg 3X Prism Scope with Shake Awake

Well made, clear glass, seems bright enough for daytime use but haven’t tried it yet. Windage and elevation moved very well when I bore sighted it in. The shake awake works only within a couple of hours. Left it on overnight but did not illuminate next morning when I picked up the rifle. Not to concerned as this is on an M&P 15-22 for training. I have Primary Arms 3X prisms on my 556 so having this Monstrum on my M&P 15-22 makes me still practice with lower cost 22 ammo. The DX1 reticle is very nice. Eye relief is ok, about 3 inches, took one star off for the slake awake not being true shake awake. Edit- Seems that the shake awake does work after testing overnight. Goes to sleep in about 5 minutes with no movement. Giving it 5 stars

Great prism for the price and very good quality . I put it on a AR and have shot about 200 rounds with it . Held zero just fine and having that etched reticle is great . Great scope for the price . Would definitely buy another for my next build

The scope itself is great, it is advertised as having 6 or more inches of eye relief, it’s actually closer to 2”. I really wanted to be able to use the scope on a pistol but my glasses almost touch the scope every time. It is very heavy for its size even on a rifle.

I was using a 1x and love it. Slapped this on and also love it. Good eye relief and great lenses. 3 shots to zero. Put the 1X on my S & W FPC and eye relief is perfect. Have the Monstrum front mount 2X magnifier coming to get longer shots with my FPC. Keep up the good work. Prices and quality can't be beat. USA made and lifetime warranty.

The reticle was very dim and hard to see in normal daylight. The eye relief was terrible and you almost had to touch the optic with your eyeball to get a decent sight picture. Would not recommend.

Glass is good and seems well built overall. Eye relief is pretty good for a scope, just don’t expect it to be like a red dot, probably 2-3 inches. Illumination is not daylight bright but is daylight visible in most conditions. We will see how it holds up. **EDIT** Shake awake feature is ok but you really have to shake it. Auto off is nice though so you don’t forget it on. It “sleeps” after 10 minutes without motion and then turns off completely after 1 hour without motion. It can wake up with a few vigorous shakes within that 1 hour.

Works great on ruger pc 9

The eye box is pretty small and finicky, but for a bench shooting or a back-up rifle, it's a great deal for the price.
