Thinking of picking up a 6mm ARC barrel from XCaliber with their sale going on. Does anyone have a recommended twist rate for an 18” barrel? They offer 1:7, 1:7.7, 1:8, 1:9, 1:10, 1:12, and 1:14. And grooves in 3, 3R, 5R, and 6.
Thanks for the info. How would you compare the smoothness and effort of closing the Ultimatum action vs. a BigHorn, Defiance, Impact, etc.? And what about build quality vs. the others?
By all accounts this seems to be well made and the people that have them, like them. Curious why they aren't more popular? JP uses them for their MR-19 rifle. I know they often require some minor chassis modifications (shorter mag catch, trimming the rear action screw, etc.). Is that why more...

I guess my question is, and perhaps this is a dumb question... how do you know if you need a cantilever style mount to obtain the proper eye relief, short of buying both types of mounts and then playing with the scope position? Is there an easy way to know ahead of time before buying the mount...
I have two Kahles K16i's mounted on Spuhr SP-3026's, which are cantilever style and 1.26“ high.
The cantilever style is perfect for this scope - because of its huge eye relief you have to shift it forward on the rail quite a bit.
I have two Kahles K525i's on order, one to go on an AR and one...
I also had a great experience with Kahles CS. I bought a K16i that had a scuff on the finish. The vendor I bought it from didn't have any more in stock so they connected me with their Kahles rep. Despite the fact he was traveling internationally, he connected me with their CS in Rhode Island and...
