I'd also be wary of that "Price is subject to change" comment.
In any case, don't have a lot of use for a $2,048 basic 5.56 semi-auto.
For ~$1,250, I can have a Bravo Company midlength with MIAD, CTR and MOE furniture, a BCM charging handle, and Troy irons.
Let's see... the advantages the Bushmaster ACR claims over this rig are quick change barrel, ambidextrous controls, mystery coating that is supposed to increase parts life and a monolithic upper rail.
Ambi safety for BCM: $25
Magpul BAD: $30
Ambi-mag release $96
Ambi-controls sub-total: $151
Daniel Defense Omega Rail (uninterrupted free-float quadrail system, not just top rail): $269
OK, so at $1,670, I have the same features as a basic Bushmaster ACR; but I am a pound lighter, am using a proven reliable platform, and have a 1:7 cold-hammer forged barrel instead of a 1:9. I also have an adjustable stock instead of a fixed stock.
Of course, instead of a quick change barrel, I have to replace the entire upper receiver to change calibers; but it is just as quick and I can actually do caliber changes now instead of some undetermined time in the future.
What about the special Bushmaster mystery coating? Let's say it doubles the life of the barrel and bolt over a BCM shot-peened, MPI bolt and cold-hammer forged barrel
Spare BCM BFH 16" mid barrel and bolt: $370
Now our prices are almost equal: $2,040 for the BCM with spare barrel and bolt vs. $2,048 for the ACR from Bud's (assuming they go at that price).
So, it looks to me like Bushmaster needs to show me that:
A) The special coating at least doubles the usable life span of the bolt and barrel as compared to the BCM midlength BFH barrel and bolt
B) The ACR meets or exceeds the reliability of the BCM mid.
C) 1:7 cold hammer forged barrel
D) Lose a pound of weight
If they can do all those things, then the price Bud's is giving is at the high end; but within an acceptable range for the features offered compared to what is already available right now.
