Rifle Scopes The Good Bad and Ugly: USO B025, Kahles SKMR 3, S&B 5-25 or 3-27?

I bought a Kahles 624i SKMR3 in June. It had to go back to Austria in October with a canted reticle and debris (about 300rds fired); I got it back in Feb. and it's perfect so far.
 
I posted something similar and got crickets, mainly because the USO is still so new, I'm guessing only a handful of folks have got their hands on one yet, let alone mounted and tested.

Yeah not a lot of Bravos in the wild yet. S&B is established and there's not much left to say about them. Kahles is popping up all over the place, and I just saw where the 624i is #2 behind the Gen II Razor for "most popular PRS scopes" at PRSBlog.
 
I'm interested in hearing feedback on the USO B series as well. They look somewhat promising outside of the fact that the B25 is longer than the entire top rail on my rifle.


Covert is as Covert does.

Plenty of good feedback on the scout site.
 
Beagle, where you're leaning is good. My issue with the USO is their FOV stinks at the low end where you need it the most (the plus side is the scope can be a substitute for a baseball bat should the need arise). The S&B 5-25 has tunneling issues that you can google if you aren't already aware, but also boasts some of the best glass out there with great mechanics and can be had for some killer deals (under $2500 new if you like the Gen II XR reticle). The 3-27 has had some optical issues that a few complained about and for the price may not be worth it. The Kahles is superb if you don't mind a bit of CA with the optics, resolution is top notch, love the top parallax and the reticles are awesome for competition/target while being a bit thin for hunting depending on what your primary goal with the rifle is.

Got Kahles K624i last summer, put it on a RPR in 6.5Creedmoor, love it. Liked it so much, I just bought a second one to put on the AI/AT that the RPR made me buy:D!
SKMR3 reticle works well for my old eyes. I can't imagine using any of these large scopes for hunting. But if you are young and big enough to pack an elk quarter on your back, guess you could hunt with it.

Where can you find a SB deal like that?
I'm very interested, and currently in the market for one.
 
Just a couple weeks ago Optics Planet was offering the deal on their S&B PMII 5-25x56 with Gen II XR reticle, with coupon it came in at like $2470 or something like that, Eurooptic.com was matching the deal. Give Jason a call at eurooptic.com, tell him you're a hide member and saw the deal, not sure if they are still offering it but that was the deal not too long ago.
 
I am not a big Kahles fan. Nothing wrong, but at a similar price point to other scopes, and some different reticles, I never bought. I have USO, NF, S&B and Leupold. I got to saw the S&B is always great, and NF and USO most of the time. I use Leupold mostly for military builds, and they are very nice, and a lot less money.
 
I have 2 5x25x56 S&B and 2 6X24i 1 gen 2 1 gen 3. I have shot both 4000 plus rounds each.
1st To my eye the glass (after a lot of side bye side shooting) on the S&B in just a little better but not by much.
2nd I like the 624i parallax adjustment being on top a lot.
3rd With the price drop on the S&B it's hard to beat. I got my last one $3300 with Tremor 3. Was going to try the Vortex RZR GEN2 but the was to good to pass up.
4th Never had an issues with either scope
They are both great scopes and will do what ever you need.
S&B is used on .338lm, 300wm, 308, 6.5 cm
Kahles used on .300wm, 308, 6.5 cm, 6cm, .243
 
I can only comment on the Kahles k624i from this list. I bought it last year, and it had some extruded o-ring protruding from between the ocular housing and the power selector ring. I believe it was an assembly error, and I gave it back to them for a repair. They currently have the scope in Austria, and I'm told it will be repaired this week and shipped back next week. They've had it for 9 weeks now. The service through Swarovski has been really good. I'm expecting the reticle shift to be taken care of, since it was probably due to the o-ring causing a misalignment. That's the bad...

On the positive side, I really like how bright the images is in the Kahles. If I compare it to the nightforce Beast I feel like the image has a different filter applied to it that favors clarity and distinction rather than color contrast. I have more experience with the Beast optics, so the others may be able to better comment on the differences they see. My preference for the elevation turret leans toward the Beast for positive clicks and the happy-feel-goods that people look for in a turret. The Kahles has very nice turrents as well, and the difference to me is the size of the clicks. I feel like the Beast has deep, decisive engagement at each delineation while the Kahles has small, sharp notches that are closer together. Both turrets are excellent.

I'll throw in the inimitable "you can't go wrong with any of those" comment too just for good measure.
 
The S&B 5-25 has tunneling issues that you can google if you aren't already aware, but also boasts some of the best glass out there with great mechanics and can be had for some killer deals (under $2500 new if you like the Gen II XR reticle). The 3-27 has had some optical issues that a few complained about and for the price may not be worth it.

The tunneling really is a non-issue though. I never use mine below 7x. If it was 10-25x I wouldn't lose any sleep :)

The optical issues that have been reported on the 3-27x are false. That was due to flawed testing. Mine is the 36 MIL version and has zero optical quality issues. Essentially it behaves just like my 5-25 except for the mechanical elevation travel available. I really don't notice the extra 2x on the top-end. I have roughly 34 MILs available for dialing, which means the tube is definitely not in an optically optimized position when "zeroed", and it still looks good. It looks a tad better around 15-20 MILs but not by much.

I believe Lowlight has (or had) a 3-27x as well that experienced zero optical issues.
 
The Tunneling is manufactured drama if someone can show me where they where using it on 5x where it matter I would really like to know ? It's guys playing with them at home flipping all the switching and fiddling with the knobs that notice this stuff. Shooters never complain about it

2 - 3-27x, no issue, the biggest problem with them was the mistake made in the PRBlog that claimed it was only a 22x because he buried the diopter, that scope was a true 27x
