Want to work up to 1000yd...need build advice on the reasonable for the rifle

[A5BLASTER]

Don't know what altitude your at but for me at 350 asl a 16 inch can't make it to 1000 with factory ammo maybe a handload set up for max speed but it would still be tuff here.

I would go with a 20 inch and go for a barrel budget of 400 min.

Glass- Well I need all the glass I can get so I vote for 20 being min top end power and like 30 for getting to 1000 yards.

I'm useing a Athlon argos right now and it has steadily impressed me.

Hope this helps sir.
