DES, you got me thinking, when I ordered my Mannlicher forearm they said it would fit from 12 gauge down. I got mine a week or so ago and it has been sitting on my 45-70 barrel which is not on a receiver. The 45/70 barrel is 22" long and the forearm looks wonderful on it. I just took it off the 45-70 and put it on one of my 24" 12 gauge barrels, one from my tracker II which is not on a reciever now since I prefer my smootbore barrel. The Mannlicher forearm looks great on the 24" 12 gauge and fits perfectly, no sanding needed buddy unless your going to try to put it on a 12 gauge Ultra Slugger or a 10 gauge....<><.... :grin:
P.S. Quick and others, no problem installing the barrel band on any barrel with a front sight that is 24" long or longer, It just slides on slick with no problem. On my 22" 45-70 barrel with a front sight I just install the forearm, hook the barrel band over the top of the front sight, gently squeeze the barrel band on the sides to slightly elongate it and it slips right on, easy-peazy, and it comes off just as easily with the front sight still on the barrel, no need to remove it at all ....<><.... :grin:
