From what I can gather it is a Turkish clone type setup that has furniture compatibility with mossberg 500 590.
Price is way better than the semi auto Remington.
I have not read much in the way of end user forum posts. I need to do that.
I have a tac14 and a shockwave. They are more on the budget end of pump shotguns, not as smooth as a wingmaster or an older 500. Completely serviceable, and very fun to shoot. Recoil control with the birds head grip is great, does not beat you up like a regular pistol grip shotty.
Kinda dated now (theres many other variants out at this point and other similar guns)but...I was really just trying to demonstrate the fact that it is compatible with a couple Mossberg accessory features.
So some basic differences:
Its a semi auto. At the time of the original post it was one of two available common variant "other" 12ga semiauto pistol grip firearms in the US.
Mossberg doesn't have a semi auto variant "other" 12ga firearm at this point.
Remington does and did have the semi auto Tac 13 at the time of the original post, but it was a higher MSRP(almost twice the Black Aces depicted).
It appears to be much more resistant to rust compared to a Remington...just like just about any other gun other than current production blued Remington. It appears to be much lighter in weight than the Tac13.
