Re: which 308 semi-auto
I have yet to own a custom DPMS AR10 or one of the POF types, but I've had all the others: Armalite AR10, PTR91, HK91, DSA FAL, Springfield SAR48, Browning BAR. I recently bought an older Springfield M1A standard model with all GI parts where it counts. It was in a loose wooden stock, but came with an
ARMS scope mount that is rock solid an low enough for the irons to also be used. I just mounted it in a McMillan stock that had previously been bedded for another M1A, without re-bedding. It actually took a couple of whacks with a rubber mallet to get it in. Nothing else has been done to it. I took it to the range last weekend, and it shot .75-.80" five round groups with BH 175gr match. It did this over and over. With iron sights, I was right around 1" groups, even with its non NM sights.
Based on this, my recommendation is get an older M1A with GI parts, install either the Sadlak or ARMS mounts, and bed the thing in a McMillan stock. All in all, I have about $2100.00 in mine. I couldn't ask for more accuracy, and I could get the $ back out of it in no time.
