Stay away from the sauce when handling firearms with large lights attached!

Since I'm a construction kinda guy, I may offer a few ideas... The first is, the ramset...you could nail it on, just make sure you nail in an area that does not interupt the mechanics of the firearm...

The second option is welding it on. No doubt there is two differing compositions of metal, so you would use an alumi-alloy welding rod...

And the third, for the man who may be on a tighter budget, there would be the all famous and popular duct tape...
