I have a 74 muzzle brake installed on my SAR-2, the brake is welded to the FSB. I want to replace the FSB with a threaded FSB and it looks like two pins are holding the FSB on. How hard is this to do? I've replaced the front sight on a Mini-14 one time and it was real easy to do. Later, a freind ask my to help with taking the front sight off a Chi-com SKS and that was a disaster. The pin flatten out after 2 hits and then wouldn't budge. Any insight would be appreciated. Also, has anyone else out there taken their muzzle brakes off and replaced them with a FS? If so, what FS did ya go with? Thanks in advance.

Its not to bad.. Ive had to grind off a little on the side of the pins to get em out...Get a good punch and you should'nt have much trouble..If all else fails drill em...

Soak everything with Kroil for a couple of hours first. The pins will drive out easier.

Educate me on Kroil, what is it and where do I get it? Thanks.

You can probably find Kroil at your local hardware store. It's a penetrating oil that loosens frozen parts. Some guys swear by it for removing copper fouling from barrels. It gets under the fouling and lifts it to be brushed out.

Thanks dude. Does anyone have 24mm bulgarian FSB in stock right now?

www.k-var.com probably has them.

Are you sure the pin spacing on a Bulgarian FSB will match the Romanian?

K-Var was going to start making Romanian 22mm FSBs. Might check to see if they are available yet.

I believe the Bulgarian FSB will not fit the SAR 2-the barrels are different diameter. You may need to wait until KVAR gets more Romanian bases in/makes their own.

They are now taking preorders by phone only for the Romanian 22mm FSBs.

Thanks for the heads up guys.

so are the FSB pins tapered? Does it matter which side i drive from? It kindof looks like they're a little larger on the right side but its hard to tell under the crappy paint.

Most people say drive from right to left-if you are looking down the muzzle. However, if it looks like left to right is correct in your case, give the pins a few love taps and see what happens.

I ended up cutting the sight bases off both my SAR 1and SAR 2. It seems like everyone else that has posted directions/tutorials had a much easier time than I did.

Also, a press is very helpful in this exercise.

MiniZ thanks for your response. I finished that little project up last night. I first tried pounding them out from right to left with no luck, then i applied the majic kroil juice and an hour latter had no problem. I used a pair of vice grips to hold the detent pin and spring in (after checking to ensure the cutout on the pin was orientated correctly) and i was done.

The K-Var brake i got ended up clocking a little to the right so that the gases will go up and slightly to the right. I presume this is the way its supposed to be to help with full auto fire right?
