M14 is the 1 gun that i dont have & have never built that i still want.
I have built a couple, not as hard an AKM/AK74. The only PITA is lapping in the bolt on a new receiver IMHE. Receivers and parts kits used to be reasonably back in 2003-2006 when I built mine, but have gone up a bit since then, yikes!
M14's are very accurate and smooth shooting rifles much like a Garand. Though I really like AK's, the M14 and Garand are my two favorite rifles.
