Also is it appropriate to say something about a system being less compatible with aftermarket accessories, and then suggest a completely proprietary weapon system? No doubt that MWS is a good deal, but comparing that specific AR-10 (really more of a sporting game gun than a duty rifle) to a base MWS is not really apples to apples. What would be a similar configuration is a DEF-10 with a free float handguard, which is more in the $1100 range.
Armalite BCG's also come with a small-aperture firing pin that tolerates high pressures better, and ship with the AR-10/A5 length receiver extension and buffer which works much better than the short system and standard CAR receiver extension other large frame AR's ship with.
I have no skin in this game and don't care what the OP buys, but the options should be represented appropriately.
