Chumlee's done partying his ass off ... in one spot anyway -- the infamous Vegas home where cops once found guns and weed is on the market.

The "Pawn Stars" cast member listed his 5 bedroom, 6 bathroom pad for a whopping $1,849,900. It's a sweet deal if he gets his asking price -- he bought it 5 years ago for $1.1 mil.

The 6,206 square foot pad has a pool, spa and guest house. It's really a bachelor's paradise where Chumlee famously partied hard ... until cops searched the house in March 2016 and found more than 120 grams of weed and 12 guns. He eventually got off with 3 years probation.

Kyle Gluhm from Realty ONE Group is listing the home, which includes the "Chum Chum" room ... stripper pole included. Strippers NOT included, we're guessing.
