In terms of accuracy and overall quality and reliability, how are these versions of the M1 Carbine? I'm thinking of getting one as a ranch defense gun, and I like the price I have seen for lightly used ones. Thanks for your feedback on this model. Yes I know I 'should' be investing in a GI model but don't have the $$ at present for one in similar condition to the Plainfield I am looking at, which will run me $400.
