You are very quickly becoming one of the most valuable resources in guntube land. Thanks for all you do!

[@4MRRanch]

I really appreciate it. My motivation to keep dealing with the KZbin BS has its ups and downs, so that means a lot!

[@madeleineollerton5993]

i hope these take a price hit when the IRIS comes out

[@4MRRanch]

I don’t see why they wouldn’t.

[@lorteti]

​​@@4MRRanch FDA will stop it from being released. If the VCSEL power is greater than 0.7mW.

[@Snapper314]

@@lorteti That is the STRENGTH of VCSEL. Each emitter is only 0.7mW, but the combined power "appears" to be greater. All legal and stuff.

[@lorteti]

@@Snapper314 It's not, FDA measure the power output at the front lens. It doesn't matter how the diode aray is made off. Because of different divergence has unknown eye damage rates. The manufacturer must provide proof that it's safe. Usually takes about 2-3 years to get approved. There is no way Holoson can get approved. Especially when they manufacture gears for the CCP military.

[@madeleineollerton5993]

really what they need is the IR half of the unit in a side saddle (mawl style) form factor where the top rail attachment is the pressure pad. I can supply my own white light.

[@4MRRanch]

There’s some major perks to have a decent white light built in. I appreciated having one less thing hanging off my gun

[@madeleineollerton5993]

@@4MRRanch the problem is on a carbine, since most of us actually use, you know, non-MP7 sized guns, I'm going to want a real flashlight, like something at the upper end of scout factor performance. so if you're using one of these on that actual rifle, the built in white light IS the extra thing hanging off the gun.

[@ViktoriousDead]

@@madeleineollerton5993there’s a serious disconnect in what people think they are actually going to us a white light for

[@PreppenWolfLLC]

I love this channel. Killing it.

[@4MRRanch]

Much appreciated! More videos in the work than I can keep up with, but rest assured these will keep coming

[@WOLFN8TR]

Cool a new 4MR Ranch video!! 😎

[@4MRRanch]

Hope you enjoyed it!

[@danvann777]

I’ve been running this same unit for over 2.5 years and love it for the size and capabilities. These are great.

[@4MRRanch]

Good to hear you’ve had long term reliability. I was thoroughly impressed with the build

[@nipsy_lafett]

I have a LE321 and love it. I’ve taken it out and put it through its paces too. Done pretty well for me

[@4MRRanch]

I’d imagine it’s hard as hell to break. Glad to hear yours is going strong.

[@connormckay9429]

[@4MRRanch]

Glad to have you here, thanks for watching.

[@Hatchet_Jack556]

I own one of these and really like it

[@4MRRanch]

Built like a tank.

[@RunningWithSauce]

I use the LE117 and a sure fire m640 vampire combo connected to a unity Axion dual switch on a .300 black out dedicated sub gun. The laser is pretty anemic like all holosun lasers so it’s fine since it’s a max 100 yard gun but really meant for use inside structures.

[@4MRRanch]

Call me weird but I like weaker IR aiming lasers to avoid excessive bloom. Obviously need to be strong enough to still pick up with your illuminator though

[@4x4le]

​@@4MRRanchi feel the same. When i watch laser reviews, my aiming lasers always seem brighter than the reviews show it would be and the illuminators seem less good or rather less needed than reviews show. I rarely use illuminators even in the woods hunting. My nods seem to be fine without illumination.

[@chrisdinarte3462]

@@4x4lewhich nods?

[@MugenZeroX]

It looks like a chonkster version of the old school Paq 4 laser

[@4MRRanch]

The aesthetics of this unit have slowly grown on me.

[@belametkat]

Great review! This or the GL4-Pro? What would be your choice?

[@4MRRanch]

In terms of proven reliability, the holosun blows the newer and less proven GL4 out of the water. The crane compatibility is a huge perk for the holosun. But the different price points make it a tough call.

[@m.k.k.4931]

This unit is great. I have the model with no flashlight or ir. Green laser high is bright. LE reasons. If the peq has a green laser then it'll be better for the price. Sighted at 30 yards

[@usernamealreadytaken770]

I was going to get one of these until I heard rumors of the IRIS (before the IRIS was officially announced). Still watched out of curiousity.

[@4MRRanch]

Will be doing the same review format with the IRIS

[@nurse-dude]

I had one for a while, I loved the form factor and packaging but all in all it was too anemic for its IR ILL and the sector switch was too cumbersome to go from WL and IR . Ultimately I decided to sell it

[@4MRRanch]

Fair enough. The illuminator on this is a bit of a bummer, especially if you’ve been exposed to stronger units and know what you’re missing. I love the build quality and reliability of the unit thus far. Really hope the IRIS feels as solid as this one.

[@hdua6772]

would you ever review their le420? would love to watch your review on it.

[@4MRRanch]

If they feel so inclined to send one my way, but I feel like it’s pretty similar to this video

[@trid1527]

Random note: Great video! I ordered an Invisible sight IS-EG NGAL back in march, it still has not shipped. I sent the guy an email and he said it will ship by the end of the month, (over 16 weeks after I ordered). Have you experienced these long lead times from IS? Is it worth it or should I ask for a refund? Thanks man!

[@4MRRanch]

When ordering through IS directly it’s very common to have absurd lead times. The owner QCs everything personally. I think 6 months is realistic for the IS-EG. Worth the wait, but also understand the frustration. It’s the one thing stopping the IS-EG from being a no brainer

[@TnTriton225]

Did they (holosun) say anything about the IRIS, and sending one to you for a review?

[@4MRRanch]

That’s the plan, and will do a similar detailed review

[@DirectActionReviews]

Any issues with the mount? I read reports of the mount coming loose under recoil and then the unit losing zero. Did you experience any of that?

[@4MRRanch]

No issues on my end. I had heard of that too and was trying to figure out what the problem was. Never came loose on me.

[@wildcat8598]

Holosun lasers are hard to beat for their price. When I go to a class or just go shoot with friends who have NV and IR accessories only their FP lasers are superior. All the civilian PEQ’s and everything else my LS321G holds up with just the same. I run a Surefire with IR & white light head just cause one thing lacking on the Holosun is the illuminator. I recommend getting the one that’s just got the vis and IR laser then get a flashlight with white and IR. Get two Modbutton Lite’s or whatever your preference switch is and you’re good to go.

[@4MRRanch]

Yeah really hoping the IRIS ends up being the laser we have all been hoping it will be

[@gwashington65]

Any idea of Iris release date? Thanks for your videos!

[@4MRRanch]

Hopefully soon, but I don’t have any more insights than you guys do! I did see it listed for $900 for preorder on some websites. I hope it’s the best sub $1000 laser out there, and best believe I’ll review it in detail.

[@roundrock63]

Question…… Since the offset is minimal, would it be better to zero it with that offset in mind so it can be shot out at any range?

[@4MRRanch]

Yes, known as a parallel zero.

[@roundrock63]

@@4MRRanch Thank you

[@Gnolomweb]

I self potted/rewired a WADSN NGAL IR. It's held zero (.75moa shift tested at 100) for 1,200 so far on 10.2 suppressed (HX QD 556) trunk gun. Why should I pay more than $150 for something like Holosun over the DIY WADSN NGAL?

[@4MRRanch]

Typically name brands become name brands due to prolonged reliability and good quality control over time. So don’t discount what that’s worth. I’ve only played with a WADSN mawl. The laser alignment was bad, parts felt like they were lower end materials, and turrets were pretty poor. There are obviously exceptions to the rule, but you typically do get what you pay for.

[@ehornad]

Comments on holosun vs GL4 Pro?

[@4MRRanch]

It depends on your priorities. I would trust the holosun’s proven reliability. The GL4 is new and although seems to be well built doesn’t have a long track record, but you can buy 3 of these for the cost of one LE321G. The GL4 illuminator is much more powerful than the holosun, but I think the holosuns white light output is a bit better.

[@williamsmith7083]

nothing better available in the youtube space, imo

[@4MRRanch]

I haven’t seen much attempts at metering data on KZbin, so trying to do the best I can. Also trying to find a balance of not spending 10 mins on a 15 min review explaining all the calculations.

[@ClydeShelton-fv1lf]

this is what i got when i upgraded from the tlr-vir i had.... works grate as an all in one device. uses it weekly in the deep dark southern Oregon woods either while rucking in the dark or shooting.

[@4MRRanch]

I like it. If it had a stronger illuminator it would be perfect

[@ClydeShelton-fv1lf]

@@4MRRanch 300 lumens for the white light is perfect for clearing rooms while not blinding you like a 1000 lumens light would, and the ir illuminator works grate at night whether in full moon or new moon. not sure you have personal experience with the LAM its self, but more sounds like you have an opinion on something youve never seen in person........ the only way your getting better is to get a potted china nock off of a real LAM or buying a Lam off some army grunt trying to make his mustang GT payment!
