Both of the mounts in question limit the rotation of the feet.

The Vltor Millennium mount especially is pretty much impossible to mount backwards.Īs for the screws themselves being backwards, again, it's not possible. If that were the case, then they would have destroyed my rails, especially as tight as I torqued the screws this time around. Like I said, there's no way the mounts could be backwards. Why don't you post some pics? We aren't asking for your help, you are asking for it. I have seen enough of their product to realize I want nothing to do with it. We had someone come in the shop last week with Odin Works stuff and issues. Most keymod mounts I've seen only have one indexing tab in the center, as with the bipod mount. In other words, the indexing tabs interface with the rear portion of the same slot that the foot slides into. Now the Vltor mount is somewhat different because it has two indexing tabs, both to the rear of the screws. For example, the Odin Works bipod mount is functionally identical to all the others on the market, with one indexing tab in the center of the two screws. But I want to emphasize that both mounts are designed identically to most other keymod mounts I've seen in terms of their interface. The bipod mount is from Odin Works, and the light mount is an Vltor Millennium mount.

Having the tab at the rear doesn't make sense.Ĭare to share which specific items (manufacturer and model) you're having problems with? I thought the standard method for securing keymod items was for the indexing tab to go into the next forward notch to keep the keymod mount from being able to move backwards once everything is tight. So if anyone is having the same issue, then it might be worth it to try this. I think tightening them incrementally at the same time is causing the indexing tab to not fully engage in the slot. My first try at a fix is going to be to fully torque the rear screw first, then the front one. The problem doesn't seem to have anything to do with the screws backing out, especially since I don't see any way a screw could possibly back itself out while the gun was leaning against a wall all night. I'm not totally unwilling to try it, but I'm 99% certain it won't help anything. I was wondering if anyone else has had any problems, and if so, have they noticed this same trend.ĮTA: I forgot to mention, I do not think loctite is the answer. This design seems to be pretty common amongst all the various brands of mounts of all kinds. The bipod adapter actually shares a common indexing tab for both screws, placed in the middle, such that it's pulling one foot forward, while pushing the other one.

This was opposed to the other two mounts, which had the indexing tabs placed to the rear of the screws, such that the tabs were "pushing" the feet forward into their little slots. Both QD sockets were designed the exact same way (one was vltor, the other BCM), where the indexing tab went to the next slot, thereby "pulling" the feet forward. I got to looking at the differences in design between the QD sockets and the mounts that had come loose, and there were immediately some obvious differences between the two categories. One of them is on an SPR that weighs ten pounds loaded, so it's supporting quite a bit of weight, and I didn't even have to torque the screws all that much to get it to stay in place. So I got to thinking, why would this happen when I have two QD sockets that have never come loose. It was sitting just as I had left it the night before. I don't have dogs or kids, so there's no possible way that it got messed with. Somehow that thing had come loose all on its own overnight. The next day I picked up the rifle and it flopped to the side. I installed it, checked to make sure everything was good, then leaned it up against the wall in my office. The first rail was an Vltor VIS, this time was with a BCM KMR Alpha. Well, a few days ago, I installed a light mount on a different rail. I reinstalled it, torqued the crap out of the screws, and wrote it off as a fluke. I had just installed it, and was sort of playing around with it and it just came loose. I wasn't even shooting the rifle at the time. A few months ago, I had a keymod bipod adapter come loose on me.
