UTG MP5 Bi-directional Picatinny Mount, Low Profile , Black

I have a Century Arms CETME with the cast stainless steel receiver . This is important to know when reading my review as the cast steel recievers may be slightly different than a stamped steel CETME. The mount is well made and is not a cheap POS . It uses the two raised ridges near the rear sight to solidly lock into and onto the CETME receiver. Once properly mounted with the "claws " firmly grabbing and latched onto the side ridges of the CETME, this mount is not going to go anywhere, I kid you not. The problem I had was that once I mounted and then tried to tighted the four spring loaded screws either the left or right side would pop out where the claws grabbed onto the receiver. Drove me nuts , until I did the following: I used a Dremel to remove some material on each side underneath the mount AND removed metal directly underneath the mount ( about midway when I noticed the mount was contacting a rise on the CETME receiver. DO NOT FILE AWAY METAL FROM YOUR RIFLE! Remove it from you $16.00 mount instead. This filing of metal allowed the mount to fit more evenly on the receiver and gave more "wiggle" room for the claws to grip the mounting points on the receiver.I loosen all bolts and made sure that one side of the mount had the claws hooked up to the side mounts of the receiver. I lightly tightened this side. I then loosened the other side until it's claws also hooked up to the receiver, but stopped at this point. On this side I now had a gap of less than 1/16 of an inch ( or less ) and I cut a washer in half so that was half moon shaped and inserted it into each claw that had not been tightened. This allowed me to tighten down the side that kept popping out and have the claws firmly latch. I had to periodically check to see that the mount was centered on the receiver, but the hard part was now solved. I now had all four claws securely latched onto the receivers mounting points without them popping out.Finally I did not overtighten the four screws but tightened just enough so the it feel firm and "right". I used LOCKTITE on the four screws. I also slightly tightened the two small screws on top until they just put pressure on the receiver, and not any more than that. I also used LOCKTITE on those. You may have absolutely no problem with your CETME, PTR , or G3. My mileage was different and I offer a solution ( with some pictures , of the washers, mounting points , and when filed and painted to be flush with the claws ),Compared to the $300+ German mount or even the $60.00 cast aluminum Chinese mount the UTG is a great mount and once properly mounted it is like corruption and politics...., it's not going anywhere and it will stick around. More work than was expected and hopefully this will help UTG or some poor soul from a 2 hour trial and error. I really like the way the mount is secured not only with the claws but also utilizing the two notched that are built into the receiver near the front sight. BTW, I don't plan to be removing this mount. Three stars just for all the work involved, but this method will work.

This review is for the UTG Low Profile Claw Mount on a Century CETME with a stamped receiver and paddle-style rear sight.First of all, this is a very well constructed mount. It's a solid piece of equipment. The claws are held in place by four spring-loaded alan-key screws (alan key supplied). In the rail itself, there are two alan-key set screws to tighten against the top of the rifle to ensure a snug fit (alan key also supplied). Be careful not to strip the alan-key screws that secure the claws. It's not difficult to do by accident. Overtorquing the screws seems easy to do as well.The only issue I had with the mount is not a problem with the mount itself, but with the rifle. I took it to the range today, and I was disappointed to find that the recoil of the rifle made the mount slide forward on the receiver until it eventually came loose. Tightening the claw screws even more would either strip the heads or compress the receiver and cause misfiring. I initially thought it was a mount issue, but after some research, it seems this problem affects rifles that do not have a "recoil stop block" in front of the rear sight typically found on the newer CETME's and HK91's/G3's. If you have a recoil stop block, this mount will work as intended. There are three grooves on the underside of the mount that will fit the block to prevent forward and rear movement, no matter which direction the rail is oriented.!! - If there is a small hole in front of the rear sight, then you most likely do not have the recoil stop block and you may experience forward and rear mount movement. This means any claw mount will have this issue. - !!The only solutions I have seen for this are to either replace (demill and reweld) the rear sight to a newer one with the stop block, or find a low-profile mount that somehow uses the rear sight base as an anchor to prevent movement. Others have tried to use set screws to thread into the hole in the receiver, but you run the risk of fouling the bolt if you do this.So far, there is no problem with the mount itself. I will probably take the rifle to a gunsmith to replace my rear sight so I can properly mount a scope on the rifle. (Search online for "demilled rear sight base" from RobertRTG.)Picture descriptions:-Top view of the receiver showing the aforementioned hole in front of the rear sight and chatter marks from the rail set screw.-Marks left by the low profile mount forward of the mounting positions. (The ones below the mounting positions are from another claw mount I tried.)-View of the underside of the rail, showing the machined grooves that match the recoil stop block on newer rifles. Notice how this mount will work in either direction if you remove the rear sight. This is good attention to detail on UTG's part.

For the price, it's a great mount. I had an old UTG STANAG claw-mount from years ago that was a huge pile of junk so my expectations were pretty low.Purchased for use on a Century C93 which can be hit or miss on being in-spec. Thankfully, mine is late production and pretty decent overall. The UTG rail dropped right on after removing the carry handle. The rail sits below the sight line so it doesn't obscure the iron sights. I haven't mounted anything to it yet, so I don't know what will cowitness or at least not block sights. With HKs, you typically accept any sort of low-mount optic is going to block your irons though.I have a Swiss-made B&T universal HK rail as well for a PTR, and I prefer the mounting style of the UTG. The clamps are captured so after you've loosened the screws to mount it, the lower clamps don't fall off under the workbench into the void of small parts. They fold out just enough to give clearance to get the mount on the receiver.I'm likely to only put a TRS-25 on it and use the combo as a range blaster. My experience with HK mounts tells me it should hold up to the task and if not, a little bit of locktite on the clamp screws would solve any issues. If I was putting it on a *REAL* HK93 and going to war, I might spring for a higher quality mount, but as it is, cheap gun, cheap mount, cheap optic.I'd also disregard the negative reviews complaining about not fitting the .22LR receivers. This is clearly a full-size product, and the .22 receivers are anything but in-spec receivers as far as HK roller-locks go.

Rail is too long to fit on my ics mp5sd. Fit great and works great after filing the rail down though.

The mounts on the left side are on a 45 degree angle so it is impossible to mount without modification no matter what make or model of MP5 you have. the right side is 90 degrees like it should be. You can actually see the flaw in the product picture if you look close. I didnt have a problem filing down the 2 of 4 mounting clamps but I would never suggest to buy this product. I never will again. you get what you pay for. Absolutely the worst quality control Ive ever seen considering the quality of machining. they managed to to a beautiful etching of the UTG logo so you remember what company not to buy.

Its a good product but it doesn't fit my hk mp5 pdw can you tell me what is the right measure for this rifle

Well made, but not stay in place

fast shippping, but I have to fit a bit the rail on the MP5
