Going through some accessories in plastic bins and found my Surefire 6P Original. Hadn't been turned on in about two years, at least. I purchased one of those cheap Chinese remote switches to mount on my AR and it worked, too. Not a lot of lumens, obviously, but it proves these are rock solid lights. I probably got this one in 2004 or 2005 from and old Army buddy at Fort Hood, TX. Was going to sell but it's a keeper. Any recommendations on minor maintenance on these? Thanks.
