BKL 257 0.6in Long Dovetail Scope Rings - 0.774in High - for 1in Scope Tubes - Fits 3/8" or 11mm Dovetails - Matte Black

Wish they came in gloss.

Rings when assembled are not concentric, appear mismatched tops & bottoms. High quality rings when assembled mate perfectly to form a perfect circle, not these. It’s as if the holes were drilled off center causing a ledge that impacts the scope tube. Save up for a quality pair of rings. Flat out, these are crap.

BKL makes the best rimfire rings. Self-centering on 3/8" or 11mm rail. Excellent quality.

Came on time and attached very easily. I used a torque wrench and tightened the scope caps to 15 in/lbs and the dovetail screws to 30 in/lbs. While sighting ion the scope the rings moved back to the stop screw, probably 3/8 of an inch travel will give them another 5 in/lbs and see how that works out. This Diana Model 34 does have some kick, I am on my 4th scope.

There's a lot of conflicting information on the 'net about what ring height to use on a CZ 455 Trainer. FYI, these medium height rings fit a Nikon Buckmasters 3-9 x 40 onto a CZ 455 Trainer with the rear sight leaf removed, and allows adequate bolt clearance. Package includes a hex wrench and clear instructions.Also FYI, you might want to use a torque driver (e.g., see link below) set at 15 inch-pounds on the ring clamps, to keep from damaging your scope by over-tightening.. https://www.amazon.com/Wheeler-Firearms-Accurizing-Torque-Wrench/dp/B0012AXR4S/ref=sr_1_2?ie=UTF8&qid=1517667724&sr=8-2&keywords=wheeler+fat+wrench+with+10+bit+set

These fit my CZ 455 17 HMR. I was going to buy the more expensive scope ring which were about $50. Then I read reviews on these scope rings that they fit the CZ 455. I bought them and they fit my rifle. Saved me a bunch of money over the more expensive scope ring which I believe were Talley rings. These even came with an allen wrench to put them on. Nice rings. I would buy them again!

These worked admirably on an 11mm Anschutz dovetail. There was minor interference with the bolt handle but it was a simple matter to grind off the offending corner at the base of the mount. I never do anything like that but this was no bother at all. I highly recommend these rings for what could otherwise be a difficult proposition of mounting an American rifle scope on a European rifle. Made in USA to boot. Excellent quality for the price.

First of all I purchased these to mount a Barska scope to my Marlin 60. The rings feel a little cheapish I must admit but their performance is spot on. I've shot around 500 rounds since I mounted/zeroed my scope and these rings still holding sight strong. The finish also goes very well with my scope and Marlin since they are both Stainless as well. Can't go wrong with them although I wish they were a little cheaper but it's a good tradeoff.
