Poor comparison IMO.
1) The VZ isn't made in the U.S.
2) The VZ is a much simpler design
3) You did mention something about surplus parts...
4) The ACR has many more parts than the VZ that require high precision
5) The VZ 58 was developed over 50 years ago, antiquated design
6) Bushmaster (or I should really say Shrubmaster) needs to recoup R&D costs
7) Economy of scale and setup costs.
8) Bushmaster dropped the ball on this one, lol.
A better comparison would be a higher end AR or the XCR.
Here's waiting to see what happens with the Beretta ARX.
1) so f'ing what?!? Compete or die
2) VZ is NOT simpler than an ACR...have you even seriously looked at them?!? Or how much more complex machining is required for a VZ?!?
3) ACR should be comparable since so many AR-15 parts are used too, scale of economy benefiting the ACR, wiping out your point
4) i'll bet thats not true. Maybe VZ vs AR, but not an ACR
5) absolutely utterly irrelevant to the point about manufacturing costs. VZ in any shop, apples to apples, would cost at least 3 times more to make the receiver than that of an ACR.
6) WHAT R+D?!?! Magpul did the R&D!!! WTF did Bushmaster do?!? No seriously, explain yourself here...
7) ACR already benefits from economies of scale from using so many M-16/M-4/AR-15 parts and barrels and magazines...and an extruded receiver?!? C'mon, this'll be the easiest quickest return on investment we'll see
ACR's ARX's as comparison are poor, because they too use FAR cheaper manufacturing methods and materials than an old-school design like the VZ, FAL or Enfield. So when you get to compare prices of the ACR to that of an ARX, all you will know is how badly the "gotta have it" crowd is willing to pay...NOT what it costs to actually build one.
The since the 1980's, military "black rifles" have become cheaper and cheaper to manufacture, and the prices have gone up and up. The profit on such rifles must be insane these days, even with R&D. Even the R+D must be way cheaper: compare the M1 Garand, designed all on paper, compared to a modern SolidWorks CAD "do it all". Magpul designed this design in under 100 days.
