For what it is worth, my Rock River 16" HB chrome lined 5.56 chambered 1/9" twist standard long length gas tube NON free floated WILL do 1" at 100 with Black Hills 50 grain "factory reloads" (or my 50 gr Dogtown reloads I worked up for it) IF I have the Bushnell 3x9 on it....and with my 54 year old eyes...which is not BAD for what was the FBI "Entry Weapon" at the time I bought it....LOL

(AND oh yeah I have the FANTASTIC 2 stage "match" trigger that comes STANDARD with the Rocks....$125-$150 or so if you want to add it to any other AR

And it is WORTH it....

With the cheap Federal XM 193s or PMC hardball that I shoot the most and the Dominator (peep) rear sight on it with the same eyes I am happy if I get 2-3" at 100...from a SOLID rest..

I remember the first time I shot it from the range at 100, with the peep sight and XM193s, just from my shooting bag as a rest...with my son shooting my Yugo /59 unmodified SKS with it's "gate latch" trigger next to me with elCheapo Wolf steel cased x39 ammo from a wobbly 2x4 rest next to me...and I was getting bigger groups than HE was...about 7-8"!!!!:eek

But with the scope and the Black Hills I shot prairie dogs out to 175 with it for two years, but yes I got "snobbish" after shooting my .30-.40" groups at 100 and 2" groups at 400 yds with my M77 VR Swift and this year the AR stayed in the case....

That being said, my next upper is already being planned...18" SS heavy barrel (maybe fluted?) free floated with a .223 Wylde chamber with my same lower I will EXPECT to shoot almost as well as the Swift if I put a decent scope on it. (I am thinking of maybe a Nikon AR 4-12x variable....)

MANY guys use ARs shooting 'dogs and targets and they can be and are JUST as accurate as any bolt gun..if they are set up for it...

The only reason I may not build up my "Varmint" AR is simply that I like to neck size only (the ONLY accuracy advantage a bolt gun has over a "modern" semi auto now) AND I don't like crawling around on the prairie among the cacti and rattlesnakes and bubonic plague carrying FLEAS looking for my BRASS
