Nice collection, darn.
I have the .30 HM1000x with cf bottle and LRT stock which I believe is the lightest way to go.
It does seem some people still don't grasp all the option of what is a custom ( tailored maybe is a better word?) options Martin offers.
If you will be happy with an "off the shelf" model ( and they ARE fine rifles) just order from a stocking dealer.
If you want a 13" lop, extra large full CF shroud, ... , ... , ...., call Martin and get it your way.
The .30 barrel ( I believe) is a proprietary made for RAW barrel. In .177 you can get the standard LW match barrel - all are hand lapped by Martin- the LW polygon barrel, Lilja,
on and on. All cal. have just about too many options ( love it) , Regulator or not, left hand action, ambi stock, excellent butt hook or mormal adjustable butt pad. Other.
