Qb78 Deluxe .22 barrel

Good QB barrel.  It liked JSB 18gr if I remember right.  

Switched calibers so it's not needed.  

It has been recrowned and cut 1 -3/4" shorter so front sight will not bolt on any longer.  

It now measures 19 - 1/16" from bolt face to muzzle.  

This is a 15mm OD barrel.  Be aware, the standard QB78 has a 14mm barrel band, most other models are 15mm.
