Light patter spring

[Chippendale]

I recall that one of the BBS members was either manufacturing or supplying main springs and I"m unable to locate the origin post.

I'm wanting to reduce the power on my L Pattern, I have looked on the Protek site and it is saying that their Airsporter springs will fit the L Pattern piston.

I have an old Airsporter spring and it does not go into the L Patter piston.

I was wondering if the person who posted about the springs will be able to help me.

I don't want to cut the L Pattern spring as it has BSA stamped on either end of it and I want to keep it original.

ok, that should give us 0.2mm of expansion which should be enough. Work out your spring room (piston internal depth in mm) and pm me your address.
