i know sir, he said "MM", so it's obviously diameter, i just added the weight, it's not really an answer, just another opinion that most airsoft sniper tend to use heavier bb, thou some uses bigger ones...(if there is, i haven't seen one either) thou most use the heavier one!!, mao gani gibutangan nakog "AND" para manag lahi sila... i think you should point it out sa nag ask ani... dili sa ako im just mere adding an opinion... naa koy duha ka lughit i've already tried using heavier bb (i think it was .30 or .25 bato... limot nako basta dili to siya .20)... ok siya basta taas ug FPS unya atleast dako na ang chance nga dili na mapalid... thou ang CONS ani niya is nihit ug mahal sad... that's why i stick .20... thou bati siya kay mapalid gihapon... labi na kung kusog ang hangin (which is sa amo game site)..., i've used heavier bb on my CYMA M14 (stock somewhere in between 380 to 400 FPS) and MP001 AGM teflon sealed thou dili tight barrel at 400+ FPS
i not an airsoft addict or afficionado so my knowledge about airsoft is limited!, if you think MY OPINION is wrong... feel free to correct it.... besides it's a free world...
