Beeman 2027 won’t cock?

The way they load opens the whole chamber below and behind the probe a pellet can fall backwards out of the mag and get stuck in the cocking mech. You will need to degas and get into hammer area to find the crushed pellet
Hate to be a problem but how do I get into the hammer area? Thanks in advance. Charles

Some how I took it all apart at least removed all screws and before starting I degassed it. Never seen any pellet parts, however I may had it one out while fooling with. The good part it seems to cock now just fine. Never did I got the trigger assembly out? Tomorrow I’ll see just how successful I was. Charles
