Definitely Rock River. That trigger break so clean it almost still surprises me.
Good enough, isn't.
I have a 20" BCM upper, a couple of their bolt carrier groups and charging handles.
The upper is OK. I haven't given it a serious accuracy test yet, I have only shot if for function checking, which was fine. My only comment so far is I would rather have the tigher headspacing of my RRAs. The BCM spits out brass that has stretched about .004" - .006" more than the brass coming out of any of my RRAs. The headspace must be at or near max on the BCM.... spent brass is show ~ + .008" on my RCBS Precision Mic and I assume there must be some spring back from the actually chamber dimensions. No check block for that on "the chart".
Because you don't like facts?Thanks for reminding me why I stopped coming here.
They do if you order a 5.56 chamber, but they also offer SAAMI .223 Remington and .223 Wylde chambers, and most of their match grade barrels are either regular .223 or Wylde. Chrome lining may also be available as an extra-cost option ($40 or so, IIRC).1: RRA doesn't use a 5.56 chamber.
1: RRA doesn't use a 5.56 chamber.
RRA ships however it is ordered by the distributor, but the default for their tactical/defensive-style rifles is a 5.56 NATO chamber, with Wylde and (AFAIK) SAAMI .223 available as options.JonB did you order it with a 5.56 chamber. Except for their match guns, RRA usually ships with a Wylde chamber.
All 16" moly barrels have a NATO chamber, while the 20" moly and all stainless barrels have a Wylde chamber.

There may be "S" & "C" after the numbers. The "S" is for stainless and the "C" is for chrome-lined.
That's debatable. Better gun? Possibly? Same money or even close? I highly doubt it.
Not everybody needs top o the line, or even middle of the line. Local availability could also be an issue. Shipping an already higher-priced weapon just makes the cost go up that much higher when, in some cases, good enough is good enough.
Oh, and the twist rate on most of the BCM, DD, and Spikes rifles are 1/7, not 1/9 unlike Stag and RRA.
