I have two of those that I bought last year. I actually own the Boker and the Stryker and yes, they are both the same light. Mine were both incans when I got them and I had a hard time finding a drop in that would fit. However, the Surefire drop in that comes with the 6P LED fits fine. I tried finding another type that would fit, but gave up. I put the 6P LED in another light. I was going to buy one of the Surefire drop ins for the light, but I thought $40.00 was too much to put into a $30.00 light.
