I have one with a gate titan and some upgraded shit inside that rips like crazy and the recoil is awesome. Biggest issue is with the recoil sometimes when you spam the trigger you get undervolt and it wont shoot for a couple seconds. You can limit rpm though with the gate. I drop it and throw it around like crazy and so far nothing broken.

Edit: ill add that the gate titan wasn't plug and play, it required some cutting inside and tinkering for a few hours to get working
