i have a 835,realtree camo,my barrel is not ported though,i think that came out after i bought mine.mine came with 5 choke tubes,2 for steel shot,3 for lead which are the only ones i have ever used,the full choke is good for squirrel hunting,the modified tube is great for rabbit and grouse,i was never satisfied with the extra full choke that came with mine for turkey hunting,so i bought a colonial arms ported choke tube,not sure what constriction it is,but it makes a much better pattern with 3 1/2" shells at 40 yards than the factory tube.the only fault i have with mine is it 'misfires' sometimes(just started doing this 2 years ago and only with winchester HV shells),which did cause me to lose a nice gobbler last spring.i first thought it was winchester ammo,but i sent some shells back to winchester for them to check,and they told me it was a light firing pin strike.i am currently trying to send mine back to mossberg for repair,as soon as i figure out how to ship it.i still like my 835,their great guns!!
