    Hello i just got this in the mail today 1/6/2020, and i have come to find out that it does not work with Romanian Draco with a 12″ barrel do to the front sight gas block combo, it has sight hood vary similar to a Chinese style.

    just to give the heads up to Draco owners.

    Does your Draco have a 12″ barrel or the 12.5″? Is yours close to fitting?

    fantastic furniture.
    It works with my 12″ Draco just fine, just had to dremel the front cutout back a tiny bit

    Fits well, if you have a Bulgarian 100 series FSB, the muzzle retaining pin is at a different position than a Russian one and will require some filing/milling of this piece
