ive made it past 2k rounds in my tisas, only had 2 times it was jamming on me
the first was the first couple of mags but i think just breaking it in smoothed off the bits with poor craftmanship and it ran reliably after i put 100 rounds through it and cleaned it
the other time it jammed one me was when i decided i was going to exclusively run the cheapest shit i could find through it and not clean it until it was jamming basically every round, it was able to make it about 500-600 rounds of questionable reloads and russian/turkshit ammo before it started to jam, purely from carbon and unrburnt powder building up in it
cleaned it after that and haven't had an issue since
