HOW DO YOU DISASSEMBLE A MOSSBERG 20 GAUGE BANTUM

Same as all Model 500's. Bolt halfway open, remove barrel, remove trigger group pin, trigger group, both shell stops, bolt carrier, bolt, lifter. Reverse to reassemble. Seriously, head to youtube and watch a video. You can go step by step with the video. The only key spot you need to watch out for is the bolt/bolt carrier when you take it apart and put it back together. The carrier will just ever so slightly clear the front of the inner rail on the receiver....and when you out it back together, put the bolt into that spot, put the forearm back on so the action bars are down next to the bolt, and then drop the bolt carrier back in to link the bolt and action bars back together. Once the cvarrier is in that perfect spot, it'll drop right into the slots. Just slide it a hair forward so the rails slightly block it in and then do the stops. Next key spot....and this is one a lot of folks mess up so don't feel bad. You aren't alone. The pins in the trigger group have to be centered all the way to get the trigger group in right. Use your fingers to center them on both sides, slip the front edges into the trigger group hole to catch the two front tabs, and then GENTLY lower the group in and pin it. DO NOT FORCE IT IN!!! Those tabs break.
