...agree with what gunplumber posted! I totally re-built one here a while back and what a time I had! I got the rifle used and in terrible shape and with broken, missing internal "parts" and thought I would tear it down and start from scratch. And in all reality, I'm glad I did...learned alot over 4 sleepless all-nighters!
The books, the manuals can only show you so much, and the rest...well your on your own. The hardest step I found that gave me the most time to figure, was the cartridge feed throat. I had ALOT of help from the members here and without them, I sure would of had a harder time. Compicated, complicated...but do-able!
Two Words; "Simple Man", song by Charlie Daniels sums up my thoughts on a "few things"!
