Firing cycle - biggest gain is to find a spring that fits the guide properly, to stop the twang. Then add a piston sleeve to stop it rattling around inside the piston, and gob some grease on it all - you are not going for FT level consistency.

All that's then left will be a bit of muzzle crack - that's part of the fun, so leave it alsone... but obviously a silencer can be fitted if you really must.

PS Don't fit a PTFE piston head
was going to try expanding!! had not considered it could break the stock...doh...I could brace it correctly. I really fancy expanding as it would fill void very well and should be the best way... and light !!
Oh shall I try it and let you know LOL !! It is near mint and do not want to break it........oh but the challenge !

As for the PTFE... ha ha, yea will give it a miss
