What are your experinces with this scope ? has it lives up to your expectations ? do you wish you have purchased another scope ?

I really like the looks of this scope with the ERGO, low profile and the 35mm tube.

I've had two, and I had to send one of them back to USO twice, but other than that it was an excellent optic. Rings were a bit difficult to find, so I just went with the USO rings and they worked fine.

It wouldn't hold a zero at all. I thought it may have been an issue with the mounts since the scope was brand new, but when I went home to check it out, everything was in order. I sent it back into USO for a rebuild, and when I got it a month later, I tried to take off my screw on eye piece cover and the part of the body under the power ring came off with the entire ocular lens. Aparently they forgot to lock tight it or something, so I had to send it back again and they offered to build me another scope.

The 3.8-22 has quite a bit less eye relief than the 3.2-17, and the ST-10 has quite a bit more than the 3.2-17.

Using the 3.8-22 and 3.2-17 side-side I never missed the add'l 5x power, though I did miss the eye relief of the 3.2-17, therefore sold the 3.8-22 and replaced it with another 3.2-17.

The 30MM tube is a different discussion. USO uses the same diameter lenses in the 30mm and 35mm tubes and puts spacer rings around the lenses to fit them in the 35mm tube. No difference in brightness, 35 versus 30 in the USO line. The larger diameter does make for a beefier scope given the physical properties of tubes. USO also says you can get more erector travel out of the 35MM tube, but you are limited at any rate by the 3 turns of the EREK knob (not that this is really a practical limiting factor).

I got my 35MM tubes when USO was running a special where you could get the 35mm upgrade for free. I would not pay for it, and in fact wish I did not get it, as the 35MM cannot be placed as low on the rifle. All things being equal, your sight line will always be 2.5mm higher than that of a 30mm tube. Ring choice also comes into play, though Seekins does make 35MM rings.

A 30MM 3.2-17 is hard to argue with.

Anyone looking at the 35mm tube I always recommend they get the 34mm tube, you get the same internal travel as the 35mm but way more ring options are available for 34mm tubes. My next USO will have a 34mm tube.

Here is mine, love it, I also made the obj. to be 58mm. Its huge, but it sees so clear and so much fov.

I wish I would have heard the eye relief comment before I did what I did. I had a 30mm 3.2-17x58 and regretted not going 22x and 35mm so sold it and went big. I haven't mounted it yet so I guess I will find out about the eye relief firsthand soon.

The 35mm tube does add a considerable amount of elevation travel.
 
Re: Owners of 35mm tube SN3 3.8-22x44 experiences&Pics

The eye relief is not bad, and actually I think its more forgiving than others in its class.

objective size divided by magnification will tell you what the exit pupil of any scope is and thus, a reference to eye relief.
As a general rule, power comes at a cost to eye relief. This is why the 3.2-17x58 has more.

I really like my 3.8-22, and the FOV and eye box are good for me in dynamic shooting situation. I usually run it around 16-18X for the best of both worlds. Its been my experience that no matter what the scope, they always seem to be best at a few X below their max.

Even mounted as low to the bore as possible (I had to shave my screw on the ERGO to clear) _9H is correct, the centerine of teh optic will be 2.5mm higher than a 30mm.

IOR makes 35mm rings that are 1.025"ish high for low mounting of 35mm's. My barrels too thisck to use IOR/Vtac lows. My TPal runs those, and my ERGO runs the USO 1.00" until I can find a pair of Seekins or other 1.00" high 35mms (just not a fan of the windage adjustable ring setup). TPS' X-low 35mm's are nice too.

Lets see more pics folks especially the 35mm tube 3.8-22x44mm as this really is a tough looking scope !!

Is the feild of view greater with the 58mm versus the 44mm ?

I think for hunting as well the GAP reticle is a bit easier on the eyes over the MPR
 
Re: Owners of 35mm tube SN3 3.8-22x44 experiences&Pics

not my scopes, the owner of these is around the forum somewhere, but I found this a while ago and it shows a good comparison between the 58mm and the 44mm's

Which 30mm tube model has 90 MOA of travel? My 1.8-10 has over 100 according to the paperwork it came with but my 30mm 3.2-17 paperork specified 64moa and my 35mm 3.8-22 80.
 
Re: Owners of 35mm tube SN3 3.8-22x44 experiences&Pics

That is what USO was advertising oh 4-5 years ago with an erector modification they did. I have not tested mine to see what they will do.

Actually testing your erector travel with an EREK is not a simple task given that the erector has more travel than the knob does. In order to do it, you'd have to monkey with the center screw and the knob multiple times to come up with the actual travel.

The 3.8-22X44mm has an exit pupil of 2mm at max power. This is much less forigivng on eye placement than the 2.64mm exit pupil of the 58mm. FOV will be similar.

What kind of hunting are you planning on doing? and if you are planning this for a hunting rifle you really need to see one in person. They are not compact scopes! The 5-25 adn 3.8-22 SN3's are somewhere between axe handles and baseball bats as far as size

I don't have any good pics of my 35mm 3.2-22X58, but here's the35mm 5-25X58 TPAL, the ERGO is the same length and girth (this has a 2" ARD/sunshade):

Fedex just dropped off my 3.8-22X58 so I thought I'd snap a quick comparison of the 35mm 3.8-22x58 with a 30mm 3.2-17X44 SN3 on a POF R308 (in 6.5Creedmoor):

SB the kind of hunting would mainly be spotlighting type work from the ute along with bit of banging steel and maybe waiting our for feral pigs etc. it would be going on a varmint weight .308......I am a bit in love with the look of the 35mm tube and 44mm objective......but I can see benefit to the 58mm I just think the 44mm version looks great.

I thought it to be a versatile type scope so much so that it could go on a medium weight long barrelled typ rifle (.300 win etc.) as well.

That looks great....what are the rifle specs and what reticle did you choose ?
