I ws looking through the BCM website yesterday to get some info on the Mk 12.
The MSRP of the upper alone is ~$1275. The MSRP of the plain jane M-4 was ~475.
Now I realize that a match grade barrel, and hand fitting will drive up cost.
But examining the specs, I couldn't find anything that, in my mind, justified a price increase of 250 percent.
Is BCM the only manufacturer of the M 12??
What am I missing?
