GM - "and similar rifles" ??

[Darkgael]

The note on the Green Mt. website about their IBS barrels is that they will fit the T/C Renegade and similar rifles. Forgive me for not knowing but what are "similar rifles" in this context?
I know that the IBS won't drop in to my GPR.

OOPs! Just saw the posts on the percussion forum about IBS drop in barrels. That partially answers my ques.

The "similar guns" are those made by Investarms and imported under various names (lyman trade, cabela's hawken, some charles daly......)
