THere is a PTR 91 for sale locally for $900. if you want details I can send to you.
You would have to go through FFL most likely since you are not resident in this state.
Mosin Nagant and SKS are low cost Battle Rifles using 7.62x54R and 7.62×39 respectively…. Cheaper ammo than that PTR 91’s .308 or 7.62×51.. shocked at ammo prices for .308 lately.
Lots of great counsel here… Let me know what you think of the book Patriots when you read it. Tons of great philosophy there. especially that hindsight is 20/20!
