I know I should know this, but can you strip the threaded FSB and 90 degree gas block off of the barrel of a Bulgarian stamped AK-74 kit and use them to replace the originals on a Romanian SAR-2?

Are the barrels different diameters or something?

Thanks,

The Bulgarian and Romanian 74s are different diameters,the Bulgarian bbl is slightly bigger.

If you can swallow the labor cost, just buy a new bulgarian front end. Thats what I did. You get the correct gas block, lugs, comp, and threaded FSB all in one shot. I did that when I sent my SAR2 in for upgrade. It has a AK100 folding stock now too. Except for the words SAR on it, I dont' think it has any romanian parts left. (RSA trigger group) I'll throw this pic up again, its the only one I have.

This is the SAR2 upgrade kit. Ditch those crappy romanian parts.
