First off let me say it will be on my SBR. Im running a TRX.
Im going with Surefire, does anyone have the E2D Defender? It looks like a really nice light. 200 lumen, not sure if you can run a tape switch though, I dont HAVE to have a tape switch.
Second thought is the Mini-Scout...w/ tape switch, 200 lumen
Im not decided on the mount yet. Larue has good deals on lights w/mounts. I really like the E2D so far and its definatley affordable.
