I am thinking of mounting a Streamlight TLR-1s on my Bushmaster XM15. I am currently running a YHM railed forend with the MagPul AFG1. First off what do you guy think about the TLR-1 on an AR type carbine? And how should I mount it? Should I used an offset or a 45 degree mount? I would love to see some pics if anyone uses this set up!! Thanks.
