OK but needs customization

View the enlarged picture and you can easily see what I’m talking about. Note the mounting screws on the bottom side and how the heads protrude. The counterbore is not deep enough to make the screw heads flush, and that blocked attachment of the device I wanted on on the bottom rail. I solved the problem, rather inelegantly, by grinding down the screw heads on my grinder (holding in a vice grip). That didn’t leave much depth for the hex wrench, and it’s easy to strip out the heads.
Next, notice that the upper 4 mounting screws are in line with the lower four screws. In fact, they use the same hole threaded all the way through the body of the mount. When tightening the hex screws on the top to attach the mount to the barrel, the last screw stripped the internal threads. Believe me, I was not applying that much torque. But the mount is aluminum, and you have to be careful. The saving grace is that the mount came with a generous supply of screws of various lengths. I used four of the longer screws and, luckily, the screw going in the hole that was stripped took a bite on the clean threads past the damage. Device mounted, successfully.
But, using the longer screws to mount the body to the barrel meant less thread length available for the screws coming up through the bottom. That’s no problem now, since there’s nothing mounted in the lower bracket. But, if I install something, like a laser, there could be a problem having enough thread length to ensure a tight grip without stripping the screws. There’s no reason the side or top rails can’t be used, however.
The hex screws, by the way, are metric as far as I could tell. They took a 3 mm hex wrench, and the thread pitch is about 36 but doesn’t match anything in my U.S. tap and die set (I was going to chase the hole that stripped). At least they provide the hex wrench. All in all, OK, and not bad for the price, but be prepared for a little “customizing.”
