pistol grip install problem

I'm really stumped by this. What should be the easiest part of assembling a stripped lower is holding me up.

I have a spikes tactical SL15 lower with a Daniel Defense lower parts kit. Everything is done except screwing in the pistol grip. I put in the selector detent, spring, and the pistol grip and screwed it in. When it is all the way screwed in its about half an inch shy of being tight to the grip, and therefor has all kinds of play.

What in the world, my only idea is to buy a shorter screw. Anyone have a similar experience or have insight why this part wouldn't work.

Depending on lower receiver, grip and screw lenght, it is possible. Not nearly all lowers have grip screw thread made all the way to the top. Long screw + certain grips = you need to shorten the grip screw.

Also, some triggers that have sear engagement adjustment screw inside pistol grip screw hole, need shorter grip screw.

Then that would be the issue. You can visually see the threading ends in the lower.

Thanks

This.
Plus some grips take up more thread length. If it's an aftermarket grip, it might be adding a lot less length overall than a std grip. I ran into this on one of my projects. short hole+thinner grip inside=an inch of extra screw. Got a shorter one, and it worked just fine.

Mark where the threads stop on the screw when it is fully engaged in the lower. Then remove, and trim appropriately with a Dremmel. Or take it into Ace and buy the correct size.

Spike's tactical lowers have 2 threaded holes In The grip mounting block. The one further to the rear is the trigger takeup adjustment. The other is the mounting bolt hole. Both are the same thread and pitch.

If yours does not have 2 threaded holes then like posted above another issue is taking place.

Thanks all, the problem was the threading of the hole wasn't all the way up. A friend cut half an inch off and worked like a charm.

Thanks.

There is only one hole on my spikes lower though.
