Did I finally find the light sweet spot?
The foxtrot msr was made for the kuna. Only light option imo unless you’re rocking the haga handguard, compact pressure switch saves your precious rail space. Leaves a bit of a shadow with a can but there’s probably an offset mount on arisaka that would help with that

My new AR needs a light
I went with a Sig-Saeur Foxtrot MSR. It's like $200 on their website, but you can get it for $180 from Primary Arms instead. It's going to be more expensive than the HLX pro and probably has seen less use overall as it's a newer release. I do like that it comes with two USB-C rechargable 18650 batte

Need a good rifle light
The company sucks, but the Sig Foxtrot MSR is pretty excellent, and it's compatible with surefire switches. It's probably the best non-streamlight in that price range. Otherwise there's Olights which have a probably somewhat unreasonably tarnished reputation due to a user error incident that resulte

Honestly I think the streamlight flickering thing is overblown. They're good to go IMO. I've had no issues with my Foxtrot MSR (got it before the whole TPUSA thing) and honestly prefer it because I can use surefire switches and scout-style mounts, but I understand why folks wouldn't buy them.

Somehow, still underrated
Sig foxtrot MSR, on sale especially it’s great value, comes with a few nice to have bits and a spare battery. The remote switch is similar to the modbutton but the unity mount required some dremeling to fit.

Foxtrot MSR Compact. Comes with everything you need to mount. Cable for pad routes perfectly as you can see too with no mess. You just have to route it between the mount and the light before you bolt them together.

Rifle lights
Hear me out... Sig foxtrot msr. The streamlight is a great quality light but uses a proprietary plug for a pressure switch. Fine if you end up staying with their stuff. The sig is also a great light in 2 sizes and uses a surefire connector. It comes with 2 rechargeable batteries and a quality pressu

First 2 stamp Tuesday
That's what I started doing was replacing my Streamlight hlx Pros with the foxtrot MSR. The MSR has a way better pressure pad than the stream lights in my opinion.

Received my Foxtrot-MSR. Once I figure out how to get the exposure right on my iPhone I'll take some beam shots comparing it to a Scout 640 Turbo, Protac HLX, and my Malkoff HTLv3. I will say it's pretty incredible how good the Foxtrot-MSR is for under $200. My first impressions are it's a much bett

HLX is plenty good IMO, i recently had the new Sig foxtrot msr, the switch is much nicer and is surefire compatible, but i still find myself wanting to use tailcap switch instead. HLX is much brighter despite their spec being similar. Ended up going back to streamlight.
