Hi i´m getting my AR15(5,56Nato) Rebarreled, and i´m not sure what barrel to use, should be a 18" Rifle one. Rifle will be used to shoot crows, geese, and varmint.
Planing to use 68 /69 gr HPBT Ammo
Got 3 Barrels that may be ok but not too sure which one to use
1.18" 223 Wylde Match Rifle-Length...
