I am looking at the M-4 LEO versions of these weapons and am interested in knowing if I'd be paying for the Bushmaster name or if I am getting a better gun for the money? I want an extremely reliable and tough rifle and have been diasapointed in the past at certain individuals at Bushmaster - so I'd rather get a better deal for a DPMS if price is the only real difference in the two rifles. Accuracy is an issue up to 100 yards. Any suggestions? Thanks.
