Tlr battery door - works well, takes some effort to install - as it should - Streamlight TLR Battery Door / Switch Assembly

The TLR Remote Switch Battery Door works well. I installed it on my TLR-1 light on my AR-15, mounted on a Picatiny M1913 rail. The door takes a little effort to close the metal clip on the latch. I used the blunt handle-end of my screwdriver to force the clip closed - it takes some effort to close the clip since the waterproof rubber gasket is new, and hasn't been compressed yet. Press it hard and it will close. Streamlight knew what they were doing by putting the retaining clip on the side that mounts to the rail because the clip cannot come open unless the light is removed from the rail. This prevents your exprensive switch door from falling off unnoticed.

Plug in your remote switch and you're fully functional. I've used another TLR-1 on my handgun (a .45) for over 10 years, and it holds up to a lot of punishment because it's got a metal case, is low profile, and it doesn't hang up on on obstacles like a larger light.

For the AR-15 you'll want the switch with the 8" lead (sire) NOT the coiled wire - the coiled model is for pump action shotgun mounting, and the longer coil is to give the user room to rack the pump and still be able to mount the switch on the pump fore guard.
