Trying to install my new grip and the screw will not go in all the way, it stops maybe an 8th of an inch from being completely tight. The threads looked just fine and the screw that was in it before came out just fine. Is it worth re-threading/can it be re-threaded? Anyone have a pain in the a$$ lower reciever like mine?

Thanks
 
Re: Magpul MAID grip

Sounds like the grip is thinner at the top. Instead of extending the threads into the lower receiver, how about a washer on the bolt?

I had a similar problem when installing a new trigger. The trigger required the bolt to extend through the receiver and hold the bottom of the trigger. I had to get a tap and extend the threads to go all the way through. Doesnt sound like you have to do that, you are just trying to use more space on the bolt to get it tight. I also might try shortening the bolt before I messed with the threads in the receiver.

I ignored magpuls directions and used my stock screw instead of the PITA slotted one. If you are trying your stock screw then I second the washer idea.

You can cut down an overly long screw fairly easily as long as you have some way to chase/clean-up the threads after you cut the bolt down. I have not done it with an AR pistol grip screw, but heaven knows it isn't that hard to do and it works well.

If not that, then your local Fastenal (or maybe a general hardware store if you are lucky...my local Ace has hex head cap screws in the right size) will have what you need. Tell them you need a 1/4x28TPI screw (as for the length, factory is around 7/8" to 1" long...can't remember which specifically off the top of my head...so you will want to go down to around 3/4" in length would be my guess). Get whatever head to the screw you prefer (whether its slotted, hex, etc.).

Good luck!

You may want to just grind the screw you have to a shorter length. Just ensure you put a chamfer on it and are careful to spin backwards to seat the screw prior to tightening so you reduce the risk of stripping threads in the lower.
