Bushmaster ACR. Really is a great rifle and design with one of the smoothest bolt operations I have ever felt... but a bit front heavy. Neglect from the factory and lack of caliber conversions seems to have created a love/hate relationship.
Just a heads up. I picked up (2) 12 round P365 mags on Grabagun for $43.95 each plus $5 shipping. I know these have been difficult to find. Great price and still in stock as of 9PM. :)
Awesome combat shotgun... However, the length of pull is very long. Costs a bit to add the collapsible stock and increase the capacity to 7 rounds. Had one... sold it. In my opinion there are shotguns with a better cost to benefit ratio.
