Where is the best place to buy an o-ring kit? (no dirty comments please.. )
I'm looking for a kit that will have all the variety of sizes and thickness I will need for my rifles.
I have a large metric kit at work, consists of about 40 -50 different sizes. Of that, only two fit my S400 (the bolt probe and the barrel 8 clamp) and then one fits a Weirauch filling adapter.
Better off working out what sizes you need, then visit your local bearing shop and buy a handfull.
