thread bbl.
Dear Shooter:
I have real problems, as WILDALASKA does with that type of gunsmithing! Not only that, but after threading the turning up of the flashider so tight that it "stretches" the bbl at the junction where it shoulders on the bbl.
Not only that, but making sure, before threading that the bore is concentric with the O.D. of the bbl., and making sure that the bullet doesn't, "wipe' the flashider!
Why a flashider? Yes, for combat o.K. but for civilian shooting leave well enough alone.
I have an AK47 with Russian sniper/range-finder scope and a 75 rd. drum magazine and I have NOT put a flashider on it. If I did put one on it would be a "VORTEX" hider!
In combat, or sniping (which the AK47 isn't suited for) you still have the muzzle-blast to score on your position!
