Re: oylmpic arms uppers
I've never heard bad about Olympic Arms. They were actually one of the original pioneers of the piston conversions. I don't have any of their stuff, so I can't swear by them. I've heard good about their NM barrels.
DPMS's quality control has declined do to the recent(last 2-3yrs) volume, that they've been doing.
Armalight is still good, from what I hear.
I have gone with RRA the last three builds of my AR 15s. I can't say enough about the Rock River Arms' fit, finish, and acuracy. Oh, and RRA's are resonably priced.
My next upper is going to be in 458 SOCOM, from RRA. When I get around to building my NM(already have the RRA receiver) all the parts will be RRA, even though I was drooling on another barrel.
There are some smaller companys doing AR10's that I think are reputable.
There are only two seasons: Hunting season, and Getting Ready for Hunting season. -DAD
