Im looking to add a light to my sbr. I've read and watched alot about Arisaka 300 and Surefire 300C. Can anyone shed some more light on the subject for me. I've hear arisaka's are under rated as for lumens and run time. Does anyone have a photos of the arisaka running..? or what the actual runtime is about? I'm used to a surefire pistol light but not rifle. Im open to both options, just looking for some feed back on both.
