Meh, he thought "good" red dots operated with laser diodes... not sure how much more wrong he could be given the battery longevity facts.

H2O is water ...?
But like Evolution said the NP3 coating is an upgrade for both friction reduction and corrosion resistance. StrangerDanger is (or will be?) working with the coating company that ROBAR used. It's a bit complicated but ROBAR and the coating company had the same parent owner (I think) but the gun specific company closed up shop this summer. I think it was a good deal to get it all at once coated and everything...but for just cerakote it doesn't seem worth is unless you REALLY like that specific color. Stranger Danger used a really cool bronze color when he refinished his well used m4.

Yeah by the looks of it, the front glass is there only to encapsulate the thing-a-mo-bober....or seal it.?
I was never trying to disprove you, I was wit you from the start.
Hey, I need a horse semen collector and I need it painted like a fisherPrice toy...............you dont happen to know anybody that could help a brother out do you?
I'm....
not going to touch that with a ten foot pole...
that's camo painted with a punisher skull

I wasn't very good at explaining things ....and Im old and have a hard time recalling any of it in the first place....sorry Scout_21.
No worries. I don’t think I was disproven about the laser aspect in HWS. I suppose it comes down to how a laser is defined. I was relying on the coherent (laser) vs incoherent (led) light source used to project a hologram. Both sources use diodes but it may be that the lines are blurred as technology progresses.
Red dot vs HWS are different systems though at least through the magnification aspect and the front glass piece of a true HWS is for protection and isn’t needed for the sight to operate.

Green lasers need a crystal to transform the 800 to 1050 nm light wave into a green 530ish light spectrum..
I thought that's why eotech didn't come out with a green reticle until recently even though cheap green led based sights were popping up on the market. The green eotechs also have a shorter run time (600 vs 1000 hrs) compared to the red laser diode based systems. More energy needed to run that diode for that wavelength

Blue line is how some of those red dot use fiber optics to run emitted light.. green thing is a pc board.......sorry for my bad paint skills..
Oh yes, the light collection based trijicons (and other makers) sometimes they have an led as a backup. I suppose that brings up the more inclusive "reflex sight" terminology

Its a laser of sorts but not what we stereotypically think as one being..
here they call the "screen" Holographic Grating...
Also, wouldn't one need a focused source of illumination like a laser to project the hologram. I would imagine replacing the laser diode with a traditional red led wouldn't give enough focused light energy to make a clear reticle. The led light would project outward from the emitter in all forward facing directions... It would probably just be a dim blur... if enough light made it through the grating and multiple lenses/mirrors to one's eye.
I'm not trying to be rude... I just want a clear understanding of the system and why it does or does not use a laser.
This image represents my understanding of the LED vs laser for use in these sights

Yes but the laser based projected hologram is why hws reticles don’t get magnified when using a magnifier behind the sight unlike red dots that do get magnified. At least that my understanding...
I never claimed that hws send out laser light externally of the device like laser sights.... if that’s what you mean by traditional understanding. -

probably all in the delivery system. I didn't design it, lol.
In the red dots, the led is carried by a fiber optic to the reflection emitter.
The holographic led goes through a screen which determines the shape projected onto your reflective glass. like a cross or circle reticle.
.
I think that answer is still overlooking some fundamentals. Perhaps my terminology doesn’t match up. From my understanding of holography one uses a laser for projection...hence the hws.
The class 1 laser designation predates green reticles.
I suppose I just want to know 100% that there are no laser used in holographic weapon sights and why Eotech and vortex would jump through the extra hoops of labeling their hws as class 1 laser products.
-
So then no lasers at all are involved in the projection of the hologram? Then why use a laser diode? Why not save the energy and just use a red LED like red dots?

Most lasers today are led powered though...

Just to be cheeky... looks like I'm going with swarovski for my next optics purchase

And the vortex HWS is also laser based.

AFAIK all HWS use a laser to project the hologram. I would love to know of an LED based HWS... that would solve so many battery life issues actual HWS face.

Eotech HWS are class 1 laser products... or maybe they just enjoy putting that sticker on all of their HWS

most lasers ARE LEDs son..... both are point-source light emissions.
glad i could fix that confusion for you
But certainly not all LEDs are lasers... Did you ever wonder why real HWS have such a short battery life compared to red dot sights?
Please look and see what type of point-source light emitter your vortex razor uses..and then aimpoint and trijicon. Are they still junk?
-
You're still confusing the matter. You're now arguing that both sights have a "light source" so they are the same.
Tell me why a real HWS won't change under magnification but a red dot will then... if they are "the same"
Educate yourself man...

not really, theyre both laser or laser from beam-splitter projections on semi-mirrored glass
False, red dots use LEDs not lasers...

Red dots are not holographic weapon sights (HWS). Two different technologies at play.

Benelli Entry barrels are imported as 18.5” barrels and cut down by Beretta USA.
I meant if someone took the stock 18.5 barrel and cut off 4.5” from it or so. I think I’ve seen some pics of a 12” m4 barrel floating somewhere around. These have no relation to the oem short barrel.
-
Am I wrong in remembering the only staked pieces are on the barrel for the ejection spring?
-
I've used Benelli for my SBS forms. Companies get bought out but it'd be hard to retroactively change the engraving on your receiver

I know this is an old thread but this is not true I had my m4 entry barrel threaded for standard m4 chokes by briley so I could mount a salvo.
I think that post might have referred to a cut 18.5" barrel and not the oem entry barrel from benelli. They both flare out and get thicker toward the muzzle and if you chopped an 18.5" barrel it would be in the middle "thinner" section.
Will I damage anything
in Benelli

It really depends on the slug. See the recommendation by the manufacturer. Nearly every foster slug I've seen can be shot through a FULL choke... I've shot hundreds though my modified with no problems. If you get peace of mind by purchasing a cyl or imp cyl choke tube go for it. I've since moved on to integrally choke barrels by benelli (their oem sbs and mil spec 18.5")
