Spike’s Joker lower built with CMMG parts kit. Magpul stock, BCM grip. Upper is a complete upper I purchased new from Brownell’s. Keymod rail, I put the picatinny section on the bottom. Also installed a BCM QD sling mount on the rail. Holosun red dot. Only test fired for function. Reduced to $650 firm. Only trade interest I have, would be a Gen 5 Glock 45
