Amen brother, I only use semi (although the vector you just sold me, its 2 shot burst is gonna get some use 😁), once played a woodland site that was running semi only that day, the layout of the site was pretty bland, nowt special, but well run & the semi rule was a breath of fresh air, prob one of the best days I'd had in years.
That aside, the only site I've visited that maintained its stringent checking/marking of guns was the mall (under Luke?), unfortunately cheats will cheat, fact of life, so unless ALL sites step up their game, nothings gonna change 😕 And before anyone says its the players responsibility etc, BOLLOCKS, we all pay for a service, gameplay, use of facilities, & most of all client safety, are what we pay for & what organisers are morally & legally obliged to do their utmost to provide. No excuses, why is it some sites can do it consistently & others fail miserably, the only answer is lazyness & poor management.
