I just scored a good deal on a R26, I have an R9 for the last 2 years, everything is factory stock. Wanted an upgraded version. Scope is in the box, never mounted. Wanted to upgrade to a better scope, any suggestions? Pros & Cons? Also any other suggestions prior to set up to optimize the crossbow?? Thanks

I put the trijicon 400-4xx on my r26. I like it. They have you sight it in at 30 and it is good inside that and then at 40 and 50 I found it an inch low, which fit in with my tolerances. And it is a bad a$$ looking combo. But a bit on the $$ side of things.

Sig Sauer Sierra3 2.5-8X30 BDX (Ballistic Data Exchange) and pair it with a Sig Kilo BDX rangefinder for auto ranging.

Optical instrument Rangefinder Monocular Electronics Spotting scope

This is the next step in crossbow optics and it's quite affordable if you shop well.

I caught a black Friday deal on the 3.5-10X42 scope for an incredible $200 and bought a Kilo1800 for $199.99 on eBay. That's a retail value of $1,050!

Here's a good deal:

This would be a perfect match to make the R26 a state of the art xbow.

Question- do you have to use it with the range finder? Are the reticles sighted in to predetermined distances?

You can use it without and with the Sig BDX app on your phone you can setup your own reticle set.

I have mine setup on my Nitro X and built a 4 reticle profile. Yardages can be any whole number, progressive value.

Thanks, I would get the combo, was curious how it worked without the rangefinder

The Kilo BDX rangefinders come in 1000 yard, 1400, 1600, 1800, 2200 and 2400 models. IF you want OLED (colored) reticle, the 1600 and up models have OLED.

Ok I see what your saying, very cool. Looks like there will be a learning curve, but very interesting, and when zeroed in, would be dead on.

It functions off the base ballistic info. you load into the scope via the BDX App.: arrow weight, arrow speed, zero distance and scope center height off the xbow rail. That's it and it's very accurate in either mode, auto ranging with the paired Kilo rangefinder or the ballistic hold mode with various BDC reticles.

I've tested it out to just over 70 yards and it was perfect. Sig has tested it with numerous bows to 100 yards.

You will see Mission offering the 2.5-8X30 combo with their 2020 lineup. Many mission dealers are already offering the Sierra3 / Kilo combos on their web sites. The popularity will grow as it's adopted and more common among the crossbow community.

My guess is you had no idea this existed, am I right?

Yes you are right, knew nothing on it. Have seen on here a few guys talking about ATN scopes, and few people recommending the Hawke scopes. I like the idea of the Sig.

I have an ATN which I use to record pic and video and use the IR night function for pig and varmint hunting. Works well but it's very big and has yet to have an OLED rangefinder to pair with for auto ranging. That will come as these optic companies advance designs and perfect an integrated laser for ranging.

Does the 3.5-10x42 work as well on a crossbow as the 2.5-8x32 scope?
I can't say 100% because of the smaller size of the 2.5-8x32 may be advantageous on some xbow setups like the very small R26 but I can say the magnification range starting at 3.5 is not an issue and the 42mm objective lens can only help light gathering. It's not likely that I will frequently use the 10X magnification but it's not a negative to have.

I easily work around the quite large ATN scope on the XRT so the "small" in comparison 3.5-10x42 scope is no issue at all.

Compared to the standard EVO-X Marksman, the notable difference is in the length at +2.75". Still not a show stopper for how and where I hunt.

I should have gone a little farther I guess. The 2.5x32 scope says it is for crossbows on Sigs website and I have read that it gives an option to set it up for crossbows in the app. Does the 3.5x42 also have the choice of choosing a crossbow option in the app?

It does. The BDX App. crossbow configuration is applicable to all of the Sierra3 scopes regardless of size.

BTW, try coupon code AGIFT15 on the Kilo1600 at Optics Planet and it's a $217.50 buy. That's good through 1/31 on $150 or more purchases or AGIFT30 on 250 or more purchases that don't have other coupons applied.

I pulled the trigger and bought the sig combo on eBay, can’t wait to get it next week and start setting it up. I’ll update here my progress on the set up.

Congratulations! That's going to be one rad little R26!

Go out the App Store and down load the Sig BDX App. You will need that to pair, bond and setup the scope and rangefinder.

There are a pretty good series of videos on BDX on the Sig web site. Of course they are all "rifle" centric but they are still helpful.

Reach out if you have any questions.

I'm expecting my Kilo1800 to arrive today!

Merry Christmas!
