Thanks yep it's looks like the SMLE etc where you push it down,but this one is real stiff and I think it pushes inwards.
As there is a small gap between it and the chamber.
More thinking needed as I don't want to pull the furniture of every time to clean the bolt etc.
Cheers

Oh! by the way I have 4 friends that I met in South Dakota at Stugis motorcycle Rally in 2010 for the rally, and the Canadianicon election results did not go the way they voted, not happy campers at all.
