These are very nice , I ordered these for my retro builds, (Black Hawk Down, Blood Diamond, and early 90’s Dissapator builds), I ordered them with incandescent bulbs, still bright enough for weopon lights today, weather your doing a retro build or not these are still viable weapon lights, nicely made, I plan ordering more with the LED upgrade for modern , ‘Truck Gun’ build, I really like the 660 and 6P profile.
