I own a Stevens 520 break down that i absolutely love shooting. I have a question about the Inertia block on this shotgun. Is the inertia block part of the breech block of this shotgun.
I have shot this shotgun many time and it cycles great. Kicks like a mule. I would like to replace worn parts. Have seen the u tube videos on this gun. but can not find any info. on the inertia block for this shotgun anywhere. any help is appreciated.
