lol if the light is just for "messing around with" is that not playing soldier?

regardless i would throw that pos away or return it if you ever plan on having a light or laser on your gun for a practical use. some cheap shit is good but really in the world of guns you should follow the buy once cry once mentality

https://www.amazon.com/Streamlight-TLR-8-Gun-Light-Laser/dp/B079C4211C streamlight light laser combo for only $174 and the light only version is $111.

but hey its your life, your money, and your gun so do whatever you like as long as it does not harm others. Have a nice day!
