Bobro Users: Is this Normal?

[Airhasz]

Do you have the scope that you are adjusting the positioning for yet? I didn't think so. Yes... QD mounts are designed to be removed quickly when necessary. They are not designed to be removed 8 times a day 7 days a week. Please listen and learn.

I've never read anywhere that their is a limit on mounting and dismounting a quality QD optic mount on a quality upper reciever. Post a valid link to this info you are freely quoting. I doubt op is playing with this Brobo QD.

I have three Bobros, and they don't do that.

Me too.

I've had a Bobro do that. It's not an issue as that part of the rail is not critical. You need to think of it the same way you do wear around the cam pin pocket.

Alright then. If that's the case I guess I will just have deal with it. But it's a little disappointing to buy a mount touted as being compatible even with out of spec rails since it is self adjusting, only to find that it causes damage. That's why I went with Bobro instead of Larue.

Are Noveske rails known to be out of spec?

Thanks.

Thank you. You are correct. I am not playing with the mount, taking it on and off over and over. I simply mounted it up in one position, put the scope on and moved the mount forward a few notches to get it where I wanted it. When I moved it up, I noticed the rail. So I took the mount off and haven't put it back on since. Hardly out of the ordinary I'm sure.

Sell the mount and move on to a Larue. All my Larue QD mounts work as advertised. I regularly switch back and forth between optics and my upper is not chewed up.

I was thinking of just returning it and going with AMD or Larue.

Then you'll be back here asking why you are getting marks on the sides of the rail from the LaRue mount. I like Bobro, LaRue, and ADM, but the truth is that any optic mount can make marks on your rail if you take them off and put them on enough. I have several examples of each brand of mount and some work better with some optics and rifle purposes than others. Marks on the rail are not how I determine which mount I use.

Bobro makes a helluva nice mount and you don't have to adjust it like the others. So choose accordingly.

The rifle is a Noveske, Gen III upper.

I checked the mount on a separate piece of Noveske Keymod and it didn't cause any damage or marks. The piece of keymod rail I have has a different coating. The rifle is anodized and cerakoted according to the specs listed on Noveske's website. And the keymod I tried the mount on is much darker and slightly textured.

I contacted Bobro, but they didn't really say much in response, just that "The index is designed to contact the rail, and it shoves itself forward in the slot. There is contact." Reading between the lines, I think they're saying to forget about it. But this isn't cosmetic. It's actually digging into the metal of the rail. and since the rail and receiver are one piece, it could be a problem if I continue to use this mount. I specifically bought a Bobro mount to avoid the issue of Larue mounts digging into the side of the rail, only to find that the Bobro is digging into the top of the rail. Lose lose for me.

So I guess I need to contact Noveske now. But I don't know what they're going to do. Other than me asking for a refinish or a new upper receiver, which I doubt will happen. I just bought this rifle about 3 weeks ago. ugh.

Noveske cerakotes their uppers and lowers. So that is probably what you are seeing.

It is working with your rail and no, there is no damage. Remember that cerakoting DOES add thickness so you are seeing wear through the cerakoting.
