Hi Richard,
Common fault with the felt & washer system, when placed & tightened the felt will distort causeing all sorts of problems, all it needs is for one of those felt fibres to throw a pellet, do you have the tool to align when assembled, it will be a steel rod that runs through the centre keeping all the baffles true while you tighten the end cap.

How would i go about aquiring one of these tools?. im pretty sure that its straight because if i point the silencer towards a light and tilt it in different directions i cannot see the edge off the baffles if you know wh
