Quoted: the bulgy bbl. has a .575" diameter and the fsb is a .002-.003" interferance fit.
if k-var really did sell you a romanian fsb (doubtful), it is .517" for the ak-74 fsb and the same .575" for the akm fsb. as k-var specializes in bulgarian parts, i'm assuming they sold you a bulgarian fsb.
besides, honing .517" out to .575" (.058" stock removal) is an all-day job with a hone!!!!).
btw, roughing the lower tang cut with a dremel, then finishing with a file is the fast and easy way to go.

I wrote down the mic measurments before putting everything back together but I don't have them in front of me right now. I have seen these numbers before but if memory serves, non of those applied to my barrel.
The FSB actually went on very easily. I just used the hone to clean up some spatter inside. After that, it slipped on without much hassle.
The Gas block was a different deal. I spent about 2 hours off and on the hone before it got to the point where it would go on with a lot of hammering. The size wasn't even close to begin with.
One thing I did though was rather than rely on scribe marks to align the gas block, I drilled an "indentation" through the hole on the bottom of the gas block before cutting off the original. I used this mark to align the block both for straightness and position on the barrel. Afterward, a little gun blue covered it completely.
As for the tang, I did consider using the dremel for the rough cut but decided against it because that metal is HARD and I was worried about burning up my nice dremel.
Thanks for the kind words guys and thank you Campy for all your info, it really helped.
A closing note about the SLR's:
I am in no way an expert but I had this rifle completely stripped and I scrubbed every inch with everything removed. I have owned this weapon for 7 years and easily have 15,000+ down the pipe and everything looks new. No heavy wearing on the rails, bolt looks new and the barrel is still mirror with sharp rifleing! The Bulgarians sure know how to make a gun. It's kinda nice to know that my now 11 year old son will probably give it to one of his kids some day.
