After looking at your pictures I realized there is something wrong with the way my B4 was assembled from factory.. the piece with the 2 springs attatched to it was not inserted into the trigger assembly like yours was, it was just riding ontop of the trigger assembly..
that tophat looks interesting, so basically yours is a stock b4 with only that tophat in it... I was told that upgrading to the QF-2 tune up kit from industry will bring the power up, know anything about this?
