I likey dat.....what brand do you have on your AR and SG? Are they Laser AND light?
I don't use a laser on long guns. I have red dots, which should be plenty, especially since lasers are sometimes more difficult to use in well-lit areas. A red dot is a bit odd for the shotgun, but it's just an extra <$100 Bushnell. I don't depend on the sight for aiming a 20" Mossberg 590A1 anyway!
I like the Fenix flashlights and have several for around the house, in all our vehicles, and for work. The products are very well made, lots of types and models to suit your needs, and less expensive than the Surefire line. I'm not busting down doors and clearing rooms, so I don't need something that stands up to everyday use and abuse.
Here's what I have on the shotgun:
http://www.fenixoutfitters.com/fenix-tk11-led-flashlight-r5-edt.-127There's a limitation with the remote weapon switch Fenix offers. It only activates on/off/momentary on. Any intensity or strobe settings require a hand on the light base. That's fine for the TK-11 light ... 2 intensity modes and no strobe. Works just fine.
For AR-15 #1, I have this:
http://www.fenixoutfitters.com/fenix-tk15s2-led-flashlight-cree-xp-g-s2-led-533I didn't add the remote switch. I just mounted it close enough to reach the main rear button (on/off/momentary). If I need the other modes, I reach forward about 1-2 inches with my finger, and the side button is right there. Normally, just lowest intensity and endcap button is fine.
COLT LE6940 AR-15: For this, I bought a Streamlight TLR-1s and mounting bracket combo from Botach.com. It connects in front of & centered on the front sight: The mounting "key" works with Surefire, Streamlight, and pretty much any other pistol-size weapon light that is thin enough to not block the sight. I could have opted for the laser/light TLR-2s if I wanted. I also added the optional Streamlight remote switch. It operates the same "on/off/momentary on" as the Fenix switch plus adds strobe mode (double-click the paddle). Simpler light with fewer intensity modes than the Fenix, but the remote strobe feature may be useful.
Note: If anyone likes the Colt mounting bracket and decides to order it, I recommend the "long gun switch" model here: http://www.botachtactical.com/kzcolt6940.html The standard model mounts the light too close to the sight for the optional remote-switch-endcap to fit. Streamlight requires you change the battery cap/switch for a longer one to accommodate the remote wire plug. If you have no intention of ever using a remote switch and have the TLR-series light, then the standard version bracket is okay. The extended one is fine for both configurations, so I'd still get that one for flexibility. If you decide to use Surefire or another brand light, you'll need to check your intended configuration to verify which mount might work for your light.For those worried about fumbling through settings and features while engaging your light during a tense situation, the way the Fenix is set up is fine. Use the extra settings when you really need them, and keep your hand off the side mode button the rest of the time. All the basic functions work from the endcap switch or remote switch.Hope that is helpful.
