I got mine in less than 3 minutes - just spawn, locate a vehicle, drive to the area immediately, mow down the chemist, grab the gun and then extract quickly. Bit of luck here and there required but it can be done in a few tries at worst and you don't even need to bother equipping a weapon either. Whether being able to give the gun to others was intentional by the developers or not, COD probably has the least integrity these days from players and the devs so if there is an easy way or backdoor, may as well take it as it wont make a blind bit of difference if it's achieved legit🤣
Gun is gonna be obsolete in no time anyway and it'll probably get shadow-nerfed as it is.
