Will? What is this Rowland carbine you speak of? How about another thread? I've been wanting one, and would appreciate info from someone who has one.
Here you go. It is a GREAT carbine in 460 Rowland. Mine is made by Mech Tech, and I got the one that works with the 1911 frame:
MECH TECH 1911 INSTALLATION AND SPECS
I upgraded mine to have the AR15 back-end, but you can buy them new like this now for about $500:
and when I got it (before the lathe), I had a gunsmith thread it for 5/8-24, and fitted a muzzle brake - I have used it with my 45cal Form 1 suppressor many, many times:
Take almost any 1911 (mine here is a S80 Colt Commander from this thread):
Keep lower and pin:
Lock bolt back on the carbine, slide lower into carbine, put pin as normal, lower the bolt forward:
It works great, but moved into the 300BLK, so not using it any more - in fact, PM if interested as I will sell it for 1/2 of what a new one goes for.
