All the typical types I've looked at just won't work . An odd shaped forearm guard is to blame . I'll settle for a clamp on on type but it's got to handle the recoil of my 45/70 punch . Most of these types I've seen just won't cut it . They are made for the smaller calibers . So's again , any ideas ? Does'nt have to be very long , like maybe 6 - 10 inches . It's not an absolute need but would just like one . The barrel is a 3/4 dia bull barrel , no taper so it should not be that hard to find , HELP ........, Love and kisses all ....!
