hw77 piston sleeve help

[p.sharp]

I thought hw's had piston liners as standard? Seems daft putting another steel sleeve inside.

Most of the twang will be from the guide imo.

Nope, sleeve not standard. Well worth doing. Its primary purpose is to stop any lube from migrating towards the compression area, but its secondary benefit is to reduce twang slightly.

I would agree that reducing twang is more down to properly fitting spring guide and top hat. If this rifle has the old metal one, you could switch that for the later, nylon one. This will reduce twang. However, custom fitting ones will make it even better.

You could buy a different spring with matching top hat and guide, but then if you have recently forked out on a new spring, you may be reluctant to spend again.

If you took the exact ID measurements of the spring, I'm sure UK Neil, Bigtoe or Welsh Willy would be happy to oblige.....Assuming here that you haven't the facilities to turn your own up.

Thanks for the replies, I will have a go at making one as Phil describes and see how it goes.

The guide fits the spring quite well, it's not loose at all but doesnt seem too tight. It goes on with a bit of a push so Im not sure how it could be responsible for the twang? hopefully this will sort it though. Thanks again for the help!!! and cheers TonyL for the names, if this doesnt work Ill see about getting some guides made up.
