This is my first post to this site and im glad ive joined love turkey hunting and calling, cant believe it took me this long to join. I have a 535 and have had it a couple years killed a couple birds with it, but i was wanting a pistol grip with adjustible stock i cant find a camo one any where i need it in the regular mossy oak break up can not find it. I know mossberg make the same gun with this coming from the factory, but i cant find it from them or after market. Next question is i want to try the jelly head maximum choke from primos, but thier site dont have my gun or the 500 (use the same chokes) listed will any other manufactures thread pattern work? Thanks in advance.
