In Russia the rifles sold to the public are modified - the bayonet mount is removed AND the bore is drilled and a piece of metal is inserted to create a unique signature for every rifle (under the hand guard).
Are your rifles processed this way?
Thank you.
Straight from the website "The rifles are reported to be in excellent condition complete with blade bayonet." (http://www.frontiertaxidermy.com/html/sks_rifles.html)
so most likely not modified?? time to send an email
