A friend has a new BT99 and had difficulty assembling the gun after he snaped the trigger with the gun apart. I do it all the time with my Perazzi. Should you NOT take the tension off the trigger spring on a Browning and if yes how do you do it? jack
Just push the take down lever to the right, and reassemble.
P.S. The take down lever frees up the cocking lever. With the take down lever all the way to the right...Make sure the cocking lever drops down. It should just fall down unless its dirty. Then just push the cocking lever down,
In my p.s. I said the cocking lever is free to move up and down by the takdown lever, however once you pull the trigger, the cocking lever will not move. To put the barrel on the receiver, just move the takedown lever ALL the way to the right. You will see the locking block move back and forth with the take down lever. New BT-99's are kind of stiff. It will go on. Sorry about any confusion.
