I did something dumb, and lost the bag of screws for my DD RIS II handguard. Anybody know what size screws I’m going to need to fasten the handguard to the lockup plate? I figure it would be quicker to go down to my local Ace, than mail order from DD.

$8.00 for a complete kit direct from DD. It shows in stock on their website. Couldn't find a reference for size or thread pitch anywhere.

thread pitch is #10-32. can't remember the lengths, might be 3/4 or 7/8.

Both, the two shorter ones are 3/4" (insert from barrel toward receiver) and the four longer ones are 7/8" (insert from receiver toward the muzzle). No sure on the six little ones with the plastic washers.

Great info, thanks!
