On the subject of TIR, I thought you might enjoy this.

I was talking to Curt at Peak, he said something about maybe making a light using this and one of the new k2's. This sucker can pull a 3 deg beam supposedly. Plus instant on.
Here are some old threads I managed to dredge up about it and it's smaller 50mm brother.

While at carlco I also noticed they have a section up for the Luminus sst-90...
EDIT: Sorry, I guess from carlcos site you'd need to go to the webshop->luxeon->other optics-> 60mm. I guess cut and paste does not work with their site. The thing looks a bit like a mix between a tir and a mirror system I'd expect to see in a telescope. Also suprisingly shallow. Somehow I know you'll be the first in AZ to have one of these mounted to your ma deuce.:devil:
Thank you Ryan. I'm digging through this stuff now, none of which I've seen before. It's quite in depth so it's going to take me a while to absorb. I think TIRs are fascinating and probably the future of LED projection. It's nice to see Surefire using them more and more and one of the reasons I'm always impressed with their products. Very few are using TIRs on EDCs.
Thanks again :thumbsup:
P.S. no longer a ma deuce in the family. :mecry: but there may be a single shot Match LAR in the future.
