Thanks, Yeah I am really getting annoyed with it being single shot got any ideas on how to build a breech for it to be semi auto loading? just trying to gather the most ideas that I can get my hands on :P

I would just add a T but because the BB barrel will be sleved inside another pipe which could make it difficult

any ideas?

thenks Dave

If I remember well you had said you had access to a machine shop, in that regard my best suggestion would be a beefy variation of the blow-forward breech.

yes I am able to use a wide selection of machines :P

I may well have a look at the blow forward breech

anything that you could tell me to incorperate into the blow forward? that would have helped you alot?

thanks Dave

Definitely make it out of steel, brass or something similarly hardwearing - and don't cut holes in the chamber where the bolt moves, to keep an additional "air spring" and prevent the thing from destroying itself :roll:
