I'm looking for a small (2-4") LED with a forward clicky. It will be mounted inside a vertical grip on my AR-15 so it has to have some durability to take the recoil of a 5.56. It must be a forward clicky as the vertical grip has a button built into it to momentary-on the light. I'd like to see 200+ lm and operate on RCR123 or whatever is equivalent. I need to be able to carry at least 2 more batteries inside the rifle so that's why I chose the CR123's. I'd like to stay under $50, cheaper would be better as I know it's only going to get beat to hell. Thanks for any suggestions in advance.
