problem is the guy lists them as invector plus chokes, and the 10ga is invector, i believe they are invector plus chokes for a mossy 835 that are overbored and the gentleman selling does not realize this and he's going by the dimensions of the choke and figuring that since they are over bored that they must be 10ga chokes when in reality i believe that they are 12ga invector + chokes, all of his other pictures of 12ga chokes clearly show the 12 ga written directly on the packaging for the 10ga ones he covers up where the packaging says either 12 or 10ga and hand writes 10 gauge, this makes me suspicious i e-mailed him about it twice and he has not responded to me so he must not be that eager to sell them
