MK Machining Rail Level

for some reason i thought this was metal, probably because of the name. its plastic, and looks to be really poor grade of plastic. when you screw down the clamp screw, it pulls the level off level, no matter how tight or loose you screw it down. if you buy one, make sure you check with a real level AFTER you install it. better yet, dont buy it, its a cheap piece of junk and im pissed that they ripped me off. i broke it apart and took the level itself out and glued it to my picatinny rail so i at least got something out of it. pathetic piece of crap..............

I installed this on several flattop receivers, several times, trying to get it level but it did not work. I install this unit on the rail then place a bubble level on the top of the receiver and level the receiver and then check the bubble on this unit. I tried ten ways from Sunday installing this unit but it was canted every time. It is also not easy to install. The screw is quite short. I had to disassemble each time when mounting. I was looking for a level that I could quickly attach and detach for mounting scopes on rifles with flattop receivers. This was not it. Close but no cigar.

Impossible to level it. The instructions say to adjust the tension to level it.Nope, that only works in one direction.I bought two of these, unfortunately.It’s too late to return them, so I threw them in the junk box and chalked it up to experience.They may have my money now, but it’s the last penny they’ll ever get from me.I wish I could give it zero stars.

I use a u.s. optics rail level to compare this to after two hours of trying to adjust this thing I could not get it to work. You get what you pay for. I sent it back.

bubble is super small, if you have trouble seeing close items then this is not for you. Item stripped easily. Its a put on the rifle and never fiddle with it.

Poor quality, doesn’t even level up.I installed this on my pic rail, and just snugged it without over torquing. Isn’t even close to being level when I put an actual level on it to check it. Pretty flimsy, I would jot recommend.

Great level for the price. Got it to see what it would be like on the gun without investing more $ in something I may take off if it doesn’t work in a hunting application. Seems fine so far. Read instructions done good info on tightening and level correction. Will get other products from this company.

I was looking for something very budget priced for a .22, and bought this. Doesn’t fit a Weaver rail and barely fits on a Picatinny rail. I contacted the company and was told it should fit and have 7-10 threads worth, it barely had 2 (see photos).
