How long are the grooves in this brake? I want to use this on a winchester 800x that has the front sight completely removed. It has a splined area where the sight was that measures .490 and then it steps up to the barrel area which is .590. I want to use a hatsan QE front sight but am not sure if it will be too long to fit on this brake.
What is the dovetail size, and is there a riser to bring that dovetail up higher?
11mm. Many 10m risers will fit it or BKL riser blocks.
.585 is the same as 15mm as used on many airgun barrels? Or, will it fit on a 15mm barrel like a HW30? Technically it's a bit smaller.
Will this fit a QB79 15mm barrel?
Will this attach to the Benjamin Titan NP 177cal??
