Tyga -- Rides Shotgun with Pistol Posse

Tyga's crew was packing heat Friday night when he and GF Kylie Jenner hit up a Sunset Strip nightclub.

Tyga had just left Hyde in WeHo when he hopped in his Rolls to drive off. The guy in the back seat was clearly brandishing a pistol. It's unclear if the armed guy got inside the club, where Tyga and Kylie partied.

This is the second time in a week armed men escorted celebs to a club. As we reported, Ray J was escorted into a Detroit nightclub with a hooded guy carrying an AR-15.
