My personal opinion is that the time and effort would be better expended on parts that are sorely drying up these days...things like bolts (and especially bolt guts!), op rods, gas cylinders, & trigger groups.

I had the pleasure of being invited to view and give my thoughts on some NEW MANUFACTURE, usgi spec, both dimensionally and "metalurgically" , made in canada M14 parts the other day. I can mention that i saw and handled them...... but i am sworn to not breathe a word about anything more than that..... i know .... flame away. These parts are not in any quantity and i didn't get to take any samples home hehehe

It seems that there is indeed others out there that are going to make it a little easier here in canada to source new, g.i. spec parts, namely bolts and oprods (one piece, forged) , rear sight pinions...... and a few other essentials to the rifle.
receivers were not discussed however, hammer forging , then machining an m14 receiver is no small task and you had better have some huge coin to even think about it.
Hammer forged, made in canada, with integral rail...... yes, if the price came in under 800.00, say 650.00 to 800.00 , I would buy one.
