Hello all, I've been checking out all the great picture threads such as "Show us your 20 incher", etc. I see lots of USO scopes in these threads but in particular I'm hoping people can show comparison photos of the SN3 1.8-10x on rifles in both the 37 and 44mm versions. I'm trying to get a feel for the difference in size between the two objectives on this scope. Thanks in advance!

Thanks MWDG3, that's a picture I had not seen before. Still, I'm hoping to see them on actual rifles. I have a hard time seeing how "normal" vs "oversized" they look when not mounted on something.

Re: Picture request: USO SN3 1.8-10x

My 58mm can look a little silly from time to time, especially with the sunshade.

I would go with the 44mm on a 10 power. I have a SN3s and the limiting factor is the eyebox, not the objective, so it sits a little high over the bore. Its just aesthetics, as the centerline is the same, but a 44 will look a little better.
 
Re: Picture request: USO SN3 1.8-10x

Thanks Glock, great looking rifles (I'm partial to the bottom one).

YN Dotte, thanks a bunch for the link. The model I ordered, the 1.8-10x44 seems to be the least common model they make (at least as far as these pictures are concerned). IN fact I don't think I saw one. Haha
 
Re: Picture request: USO SN3 1.8-10x

Lol I gotta say I don't see very many of them. I think alot of people go for the higher magnifications. I really like the 1.8-10 models, IMO they are perfect for a SPR builds or as hunting scopes.
 
Re: Picture request: USO SN3 1.8-10x

Hey Jedi, I think the reason you don't see many of the 44's is for about the same weight you can go up to the next power range. The weight savings is really with the 37mm. Look at the thickness of the objective housings on the 37mm vs the 44mm in the side by side pic, huge difference. That's why the one I just ordered to replace my 44mm is a 37mm. It'll be at least a 1/4 pound lighter on the front end, about 10mm narrower OD and about 10mm shorter.
 
Re: Picture request: USO SN3 1.8-10x

Your reasoning makes perfect sense NoExpert, but the wider objective lenses always appeal to me for low-light shooting (not that I have done much of that at this point but who knows down the road. Hehe

By the way, which model is that on your EBR in your sig?
 
Re: Picture request: USO SN3 1.8-10x

I thought the same thing with the light gathering when I bought my first scope, also the larger exit pupil. Then I tried a friend's 1.8-10X37 in low light and saw there wasn't much difference, at least not enough to justify me carrying the extra size and weight around.

The one on the EBR setup is the 1.8-10X44 I sold.
 
Re: Picture request: USO SN3 1.8-10x

NoExpert, Ive been looking at the 1.8-10 as well. Since you have on hand experience and are getting another one... which elevation and windage options are you going for this time around? and other options if you feel like elaborating.

I had the EREK and US#3 M40 with windage stop on the last one, both MIL. The new one will also have the EREK knob but I'm getting the US#1 with cover and US#1 M40 windage knobs. This will let me run either a cover on the US#1 knob or run the exposed US#1 scalloped M40 knob. Elevation and windage will be MIL again. Both scopes have the windage left handed (I'm right handed). This is so when I'm shooting prone I don't have to reach over the scope or take my right hand out of a firing position to adjust it.

I opted to get the internal bubble level in the eyepiece, just makes sense.

Illuminated reticle (getting their new digital setup) in red. Since the human eye doesn't perceive red as light it won't affect night time vision. I researched this for hours before deciding.

I had the JNG MIL reticle on the last scope, it worked well. On the new one I'm going GAP MIL, less clutter and hoping the numbers are easier to read at low magnification.

I opted for the ERGO adjustment instead of T-PAL. It's more forgiving on the settings (you can set it to 200 yards and it'll work out to about 500 yards) and for me it's faster (just turn to the setting, don't need to always start at infinity). The 1.8-10X is not much more of a reach than T-PAL, I think 3 or 4 inches. It's also one less knob on the turret block making it easier to get my fat fingers on the windage knob.

The last scope weighed 2.25 pounds with sunshade/ARD and USO lens caps installed. I'll be weighing this one when I get it to see how much lighter it is.
 
Re: Picture request: USO SN3 1.8-10x

Thanks for the added info NoExpert! Even though Minuteman was the one who asked it I enjoyed the answers as well. I ordered the JNG MIL on mine. I haven't seen it in person but of all the ones they offered it looked the best to me, at least by diagram. You're probably right about the clutter but my mind just can't wrap itself around the GAP type reticles. The thick posts have to be the same length for me. Haha

You make a good point about red not ruining night vision. I went with green because I read that it is more visible to people like myself, with a color deficiency (I learned that colorblind is non-PC

).

1.8-10x44 w/JNG MIL reticle. Perfect size and power range IMO. Good for closer shots at low power thanks to the reticle ring and 10x lets you get out there. I ordered a 3.2-17 for this but it was too big and moved it over to my bolt .308.
 
Re: Picture request: USO SN3 1.8-10x

Thanks for the pic Falar. I'll be putting it on a bolt gun, but not a huge bolt gun...an XCR compact tactical, 20" barrel. I was afraid the 3-17x's would "overpower" the rifle. Yours looks just about perfect for it.

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Minuteman</div><div class="ubbcode-body">falar, while on the 1.8x you can pick up your sight picture pretty quick? compaired to a red dot how much more difficult is it? </div></div>

Since it is not even close to true 1x it is not nearly as fast as a red dot. 25-50yds out though I would say it is pretty fast, faster than an ACOG anyway.

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Minuteman</div><div class="ubbcode-body">Yea thanks for the insight. Im curious about the weight too.
there is an internal bubble option? didnt see that on their web page. </div></div>

There are a few options that aren't on the website. Jeff is in the process of making a new site but for now it's mostly word of mouth or ask questions.

There are a couple reticles available that aren't listed, the internal bubble level, 34mm or 35mm tube option (I went 34mm), T-PAL on the 37mm unit, having the sunshade cut down to 1.5" if you're having the ARD installed (also having this done), personalized serial numbers (having mine matched to my rifle)... It's a custom scope shop, just have to ask what's possible.
 
Re: Picture request: USO SN3 1.8-10x

Thanks again for the info NoExpert. By the way, everytime I see where you are my mouth waters..."D'elias Grinders" on University just east of the 91 has the best sub sanwiches in the world.

Indeed they do. Subway could take some lessons.

USO is great to deal with.
