    My top lever spring seemed very stiff but it was moving during firing to the point where the locking block was marking a line on the lower monoblock. Replaced the top lever
    spring and all movement went away.

    Is it the top lever moving or is it the forend breakdown (take apart) lever? If the later it seems that it should have nothing to do with top lever spring or locking bolt. I have had four BT-100's and all were extremely tight, as new. The forend lever on all would little by little open as rounds were fired requiring pushing back to the fully closed position at each post. I was told that as the gun was shot more this would stop. Never shot any of them enough to find out. Marc

    I would ask, how are you closing the gun? My experince with a few new BT-99s is if I close the gun letting it release the locking bolt on its own, the top lever never moves when fired. If I hold the top lever while closing the gun and then manually release lever after gun is closed, lever will very slightly move when gun is fired. I am thinking the bolt is not fully seating when released manually. Thoughts?

    Firefoxverigo , I took the stock off my BT100 and looked at what's going on, haven't had mine long.

    The bottom of the hammer, at rest, bumps against the back of the top lever dog. That is what causes the top lever to move when you fire the gun.

    You do mean top lever ,right, not take down leve

    NO dog in the hunt BUT, Replace the Top Lever(Breakopen) spring and you are ready to go. ALWAYS-ALWAYS-Shut the gun Firm but gently so the Locking block "Locks" in place Good. JMO- Joe joe90t

    Joe, Ever look inside at a BT100? Mine has new springs from Jim Flynn. The hammer bumps the top lever dog when fired. That makes the top lever move.

    Remember to take a coin and release the button on top of the breech face to let the top lever return to strait position when storing gun in break-down case, this keeps the pressure off the spring. I also pull the trigger and keep the coin over the firing pin to let off the hammer spring as well, only takes a few seconds to do both. Kill two birds with one stone as they say. break em all. Jeff
