Ahhhh, Gotcha....My bad Mesca. Misunderstood/read. Think a rebuild ether way would be good.
Agree. What I meant to say, is that people doing clones should try to replicate the varnish type finish. Epoxy impregnation was highly recommended and I believe many M40 rifles were in fact, re-finished.
Depends if building a out-of-the-shop clone, or a field rifle...
