I don't know one AK from another, and, I don't know this guy or will make a dime from it...but, this is on another Fourm. Maybe something here will help you...
Thanks for the offer. If only some of it would work, The RPK is a heavy barrel and is different size than the M70. It's gonna be tough finding this stuff.
Sorry about that. I forgot about the RPK having the thicker barrel. The FSB in the ad is gone, but check around because I think they are the same as a standard Yugo AK. At the end of the barrel on the RPK is turned down where the bipod and FSB attach.
Yep, sure is. Sad thing is I was looking at a barrel assembly when I posted above. I'll keep an eye out.
Are you getting ready to build a kit? If so would you mind helping me out with a build? I just got the rivet set in today, that was the last thing I was waiting on.
