Krink FSB

I just recieved a Bulgi Krinkov FSB from k-var today to do a fake-up krink build on a Romy G kit, and was wondering what this hole that runs the length of the site was for, in the pic it's on the left. Holding the weapon it would be on the right.

I think you are looking at the hole that the muzzle brake plunger and plunger spring go in. It's what locks and holds the brake in place and there would be a corresponding hole for the plunger pin that holds the plunger in.

Thank you, I did not notice the fact that there wasn't a spring there. So guess I need to find one. Will the spring and pin on the original Romanian FSB work, also this thing is new never installed on a rifle, as such it is not drilled for the roll pins but the gas port is drilled if anybody cares.

I'm not sure if they interchange but would think that they do. I never have measured them.
