**Thanks for the advice guys, stopped by Ace, good to go now**
Ok, I'm an idiot, I was changing the grip on my AR, took off the original, then got called away for awhile. Came back to it and I'll be dipped if I can find the screw/washer to hold on the new grip!! Where in the south Denver area can I get a new one without buying a complete spare parts kit? And if I were to buy a kit which is the recommended brand (the gun is a Colt 6920)?
This idiot thanks you.
