Hello, I have a Browning 725 High Rib Sporting 12 gauge and recently purchased a set of new Briley 20 gauge tubes from a guy for $150 that he had won at a shoot but they are 32" and he has 30". I got them out today and noticed they said Invector Plus on the tubes. My 725 is Invector DS. So I've decided to research a bit before heading out to shoot. They fit good and tight but I'm wondering if there's maybe something that I can't see that might be a safety issue. I'm going to call Briley tomorrow to see what they say about it, but figured I'd see if anyone had any thoughts about it. I'd hate to screw up a $3500 shotgun over something stupid. Just want to make sure this is safe even though everything seems to work correctly.
