I have just sent my R10 MK2 and my sons Ultra SE, full blue print on the SE and gnarled cocking lever and JB silencer. My R10 is having aluminium bottle, JB regulator, full blueprint, gnarled cocking lever, JB silencer. I can't wait to get them both back. They where great rifles to start with except for lack of consistency on the R10. This little lot came to just over £700. The SE was £228 if I remember rightly
