So I just bought one of these grips. When I got it, the bolts were somewhat loose in the threaded portion of the grip. You could wiggle them forward and back, side to side. Not only that, but they were too short to actually mount on a rail. So, I called up the CQD and they sent me some new bolts. What's weird is that they are still pretty loose in the threaded portion of the grip. (When threaded without any tension.) But, I am able to tighten them down really tight on the rail since they are longer. My problem is that I'm a little worried that the threads don't have as much contact as needed and will distort and strip over time. If this is the case, I could just use longer bolts and add locknuts to the end of them. Though, I would prefer not to do this. FYI, the locking plate has heli-coil inserts. So my question is this: For those of you who have a CQD vertical grip, did your bolts fit loose in the threaded portion(locking plate) of the grip? Thanks. |
I have a CQD VFG that's currently uninstalled......went and took a look at it. I have the locking plate snugged down pretty tight against the body of the grip and the bolts aren't "loose" in any way that I can see. There is a small amount, perhaps half a millimeter, of unused thread on the outer side of the locking plate. This grip was installed on a rifle that saw at least moderate use. I never had a problem with any loosening, FWIW. HTH. |

Could you possibly remove the locking plate and then thread one of the bolts through just the locking plate? It's when I did that, I noticed the bolt fit loosely. Like a fine threaded bolt through a course threaded hole. It's loose in such a way, that I can move the bolt around like a joystick. (If that makes any sense.) When tightened down against a rail, it fits tight. I'm just concerned about the threads having less purchase and stripping out. Thanks again. |
You might be on to something here, unfortunately.  When I put the cap screws in the deteched locking plate, I don't get any play whatsoever. In fact, I can't hand-drive the screws any deeper in the holes in the plate than I can when I have the plate mounted to the grip and use a driver to snug them up. Maybe your cap screws are out of spec? |

At first, I thought the bolts were out of spec. But since CQD sent me new ones, I'm thinking the bolts are correct and it's the threaded heli-coil inserts that are out of spec. Though there is no way for me to know since I don't know what the fit is supposed to be like. (Still, I definitely needed new bolts since the ones I had were too short.) Interestingly, it sounds like your locking plate is a different design than mine. The design of mine is threaded all the way through It sounds like yours isn't tapped all the way through. Mine might be a newer design. This picture shows a locking plate different than mine.  Mine looks more like the locking plate in this picture.  Except on mine, there's very obvious steel heli-coil inserts. |
Mine's threaded all the way through -- I can see the threads on the off side of the retaining plate. I just can't get the screws to drive all the way through under hand pressure. FWIW, I don't see heli-coils in mine, but it's at least a couple of years old. |
