My 25x45 AR

[7.62 Nato]

Thanks for the information. I don't know a lot about the 6x45 yet, and knew nothing about the 25x45. From what I understood, the 6x45 doesn't need to be trimmed to length after necking up 223. What barrel length, gas length, and twist did you use in your 6x45? I'm looking at carbine probably.
