Recoil Resistant Flashlight
 

I have a ACM M3X on my C8 GBBR at the moment. This weekend I changed out the buffer for an RS one, and while recoil's been improved to the level of a 22LR, the flashlight is being jostled enough that it lights up every time a shot's fired. So, I guess that means I'm looking for a replacement flashlight that's more recoil resistant.

I was looking at the Surefire 6P or any of the related Fenix lights, but at the moment I have no idea which light's best for mounting on a rifle. Ideally it'd be capable of at least 200 lumens. I'd prefer metal build, CR123 batteries, and a momentary on tailcap, but I'd like to hear your suggestions so I won't make another mistake.

Surefire 6P will be tough enough, you will need a mount to put it on your rifle.
But, it is only about 60 lumens.

Alot of more expensive Surefires have special bezels that compensate for the recoil of a rifle, typically their weaponlights. The 6P though should be fine for the recoil of a GBBR.

Fenix TK12 or TK15.

I have been using the G&P M6 Huang sells and it has been trouble free on my WE M4 even at full fps. The tape switch kicked the bucket, but I prefer the button anyways.

You working indoors or outdoors?

check out the flashlight store on ebay, they sell surefire type high quality repros, spiderfire, angelfire, etc
REALLY nice damn flashlights, all pre-upgraded, all under $40!
They've got stock and recessed end cap buttons, never had mine go off even dropping it from 3 feet

Surefire, Inforce, Fenix TK series.

ebay, get an Insight M3X for around $100 shipped.

Indoors primary, but I also do a fair bit of outdoor.

The Inforce is right out of my budget, and so are most of the Surefires. I was looking at either the TK12 or the PD32. The latter mostly because it's slightly cheaper and slightly lighter, which helps this already ridiculously forward heavy rifle. Thoughts?

Check out Elzetta ZFL-M60. Made for mounting on guns, small, super bright but heavy and expensive. But they're indestructible and upgradable with many different options. Replacement parts can easily be obtained directly from their website too.
