I suppose I could let my Xtra go. It's 100% mech - so punter abuse isn't a problem. Oh, I've changed the feed neck from that crap see-through screw thing to a push on - much nicer and punter friendly.
I think I have an old AA 1-piece for it somewhere as well (also got a freak back if you're interested in that).
i have a spyder 2 with a 16inch barrel it up graded on bolt and i think im nt sure the anti chopping springs it has 9inch barrel to my email is popcorn843@hotmail.co.uk
