Hi,

    I was having trouble with my bolt latch and when I took the screw out to look everything over, it just crumbled to pieces. Does anyone know the screw size for this. I have a lathe and I'm thinking of getting some headless allen screws from ACE and making my own. Thanks

SI Defense also sells a stainless replacement - not sure what the base-size is the the allen...  <dontknow>

Ask them to mail them to you USPS - alot cheaper that way.  I know why you buy them from their online web store, the shipping is about $12, by default.  <thumbsup>

Do yourself a favor and call to order the screws from SI Defense and ask them to mail the screws in a padded envelope or you'll end up paying $12.00 shipping. The screw size is 6-32. Drill a 7/64" hole and thread 6-32. You'll have to make extensions for the drill and tap or you can get the aircraft length drill and the extended tap from TruCutMFG.

Forgot to mention, only open the back side of the hole to 7/64" and thread the hole so that the screw sits flush to about .010" below the surface of the threaded boss.

Hope this helps.......

That dill/tap combo is genius,but you don't put that on handheld drill motor right? <dontknow>

You can, but I would not. I have seen many done with a hand drill and they come out perfect, but that's just not my style - my 2¢

The DPMS .308 lowers come threaded, and with a screw - the screw is weak, and you have to be careful with it, but they all come that way.  <thumbsup>
