Guys, the Apache rests have a loc-tite "patch" on those adjustment bolts/screws. That "patch" is there specifically to eliminate the likelihood of those bolts working loose. The issue can be, often, when the person puts the rest on and tightens down those bolts upon adjusting their rest, they feel the resistance from the "patch", and they think the bolts are fully anchored down tight—when in reality—they've simply hit that patch, and it's offering resistance as they tighten the bolts down. What you have to do is go ahead and crank down and force the bolt on through that patch so that those bolts/screws are fully tightened down! I actually encountered that very scenario two years ago at the BH.com G2G shoot. One of the shooters there was having an issue, and I immediately grabbed his rest and realized it wasn't fully tightened down. Cranked it through the patch and bottomed it out ... problem solved. My advice is that when you get to a point where you "feel" it's tight ... go ahead and crank it down a bit more, see if in fact that it's completely anchored down. The loc-tite patch will offer quite a bit more resistance than one might expect, so some folks simply stop once they hit the patch, and don't quite get it fully tightened. Like I said, I've seen it firsthand myself on a couple of occasions, even with my own Apache three years ago. You just have to make sure to be mindful to fully tighten it down. When you first feel some resistance as if it's fully tight—go ahead and give it a bit more bite and see if in fact you can turn through that "patch" and get it fully tightened. Hope that helps!
