I ordered a new Zastava ZPAP that should be here in a few days. It comes with a krinkov style muzzle device (pictured above) which originally these were used as a booster to increase recoil and improve cycling but this one is just an empty can sort of like a "fowarding device" aka "not do much of anything" I stumbled across a picture of one of these with holes drilled in the top... And i thought "now thats interesting". I think it would be awesome to be able to keep a traditional AK style but get some compensating effect out of the piece. My question is, What pattern would you recommend I drilled? I was planning on basically copying the above and drilling two holes off center so the blast isnt going straight up...but then i was thinking how the most effective comps I have used had side cutouts with nothing on top. Maybe 4 holes in a "V" pattern? I know there are some smart gun people on here so curious what you would suggest. thanks.
