I went from a M14 clone, to a PTR-91..Why? Accuracy is as good if not better than the M14 clone I had, Mags, as you already know are dirt cheap, and reliable,($2.00 apeice almost new,vs $20-40.00 apeice, you do the math) Parts...Available, and also very reasonably priced something M14parts of any kind anymore, are not. Optics are not hard to mount, and there are a few stock/handguard options also available. The only thing a PTR needs out of the box is a trigger job, I'm getting one done, this is also reasonable ($51 return shipping included) Ar-.308's are very accurate rifles. I briefly considered buying one before I bought the PTR, But the big drawback for me was the price of mags, and I'm not too sure what AR-15 parts interchange with the lower if any at all, Availabilty of spare parts is important to me, and that's another reason I passed. Armalite has gotten their Ar10 mags down to about $25 apeice, DPMS however, theirs are $40.00 or more apeice..not what I call a bargin.. The Egro's of the HK types is'nt for everybody, But I don't find them a problem, I'm real happy with my PTR.
