Muller 12 gauge Invector Plus Choke Tubes

I am selling 2 like new Muller 12 gauge  Invector Plus choke tubes. One is a U1 and the other is a U3.   U1's are considered skeet/improved cylinder, U3's are considered modified /improved modified. A U1 is good out to 35 yards. A U3 is good out to 60 yards.   I am selling these and a number  of other items  for an old  hunting and shooting buddy of mine who's health is failing and he is just selling things off. He bought these chokes, put them in his gun but never shot a round through them. They are as new. As with all of these items,  I'm trying to get my buddy a good portion of his money back and also get the buyer a good deal. To order these from the US, they would be $140.00 Canadian each, plus shipping .
