I would respectfully submit that you need to know what you are buying, the current production for the majority of the DPMS patterned uppers available in my area is the low. The high went out of production pretty fast after the design change in 2009 (?) with the trend towards light AR builds, JMHO.

The PSA .308 parts are DPMS patterned.

Keep watching the Aero website, I picked up a .308 upper last week. They had a pretty good sale over the 4th of July, and the inventory is just now coimng back on line in their web store.
