Needing some help. I recently purchased a browining b78 25/06 (dont know how old as i have not checked the serial number yet.) It has the pachmayr inserts installed for the sling loops. My problem is that the loops themselves are missing. Brownells tell me that the new style loops are a different size and will not fit the inserts that i have. Would really like to be able to put a sling on it but cant till I can get some sling loops. Any thoughts would be greatly appreciated.
