I inherited my dad's dedicated zombie slayer. It's an 8 shot with 20 inche barrel. Dad had a pistol grip on it, already tried the pistol grip shotgun thing many years ago, didn't like it, was able to find the original stock so I put it back on. It has the standard pipe barrel with no choke. I also tried the no choke barrel thing many years ago on my S12 and didn't like it, got a polychoke and massively increased its utility. The S12 and its no choke barrel was pretty much limited to blasting shtuff at close range and that's about it. With the polychoke I could actually take it hunting. (Note I don't want a polychoke for the mossberg) Does anyone know if I can get a 20 inch barrel for an 8 shot that takes screw in chokes? Or am I hunting unicorns? I tried searching for one but there are sooo many 20 inch 8 shot barrels out there, most appear to be no choke, some have a fixed choke or the description didn't mention the choke at all.
