That Mil test didn't have squat to do with sales. Mossberg has outsold Remington for the same reason WalMart has about put everyone else out of business - they're cheaper. If that's your #1 priority, then have at it.
220,000 extra sales in the past three years....that number pushed the Mossy past the 870 for the first time ever....*and*....and this is the big and here....the Mossy 590 as provided to the mil actually cost more than the Remington 870P at that time.
Didn't have squat to do with sales, huh? Should I bother going back and counting the number of times folks have considered those mil tests in their decision to buy the Mossy *in this forum alone*? What is it, ten times in this *thread* alone?
Remington didn't bother to enter a gun.
Because they didn't have a gun to enter. That's simple enough.
