Need to choose between 10pc or Hog Hunter in 223

The 10pc is available for $600 locally. It is "used" but unfired. Has camouflage AccuStock.

Alternatively, I could get the Hog Hunter and swap the stock for a B&C M40 stock. The HH would run me 500, the M40 stock would be 270, and PTG bottom metal for AICS mags would be 130.

The real question will be how does the accustock compare to the B&C M40? Any difference in accuracy or comfort, and is it worth the premium?

Related question, does PTG's bottom metal fit the 10pc? Or are there aftermarket 10 round magazines for the 10pc?
