yes, i would think of bad reloads' b4 i'ed blame the weapon' ... as whtsmoke says, they not all bad...
lowers, for AR's are exactly that... a lower.
dont mater who made em. an AR is an AR... is a AR.
i roll my own now' but ANY AR can be upgraded.
i putt a BCM carrier n' bolt , and a tubbs carbine spring in a DPMS, and it runs like a sewing machine.
olympic arms are all forged now. nothings been made cast, for many years.
my next rifle. ? if i was to ever buy one. and not build it myself, i'ed buy the olympic plinker 20'' rifle, with the A1 sights.
to me, thats ''perfection'' a rifle with oly's [great barrels] rifle gas system, and set and forget A1 sights.
my .0000000002 cents worth of opinion...
