For what it's worth I have 2 sets of companions. I have a 12ga to 20ga. set & a 12 ga. to 28 ga. set. I do like both of them alot. These tubes I have are for 30 in. barrels & have choke tubes in them. I also have a set of 12 ga. to 20 ga. chambermates. No comparison, I guess the you get what you pay for adage is true in this case. The chambermates use a rubber o ring that is always breaking, the companions fit as Smithy47 mentioned. On my 20 ga. set I do have to use skeet chokes to fit them in, however, my 28 ga set fits fine in all but one of my full choke guns??? Hope this helps some. Colonel
I have been on their web site and it does not say much about anything. Thats why I am asking. Their web site is useless except for prices and they are high. I can buy the same tubes made by Briley sold by MPC Sports for $150 less than Briley has them listed for on their site. Whats up with that?
