Hello everyone I am new to the forum and fairly new to rifles other than your basic handguns and deer rifles, I've been wanting a semi auto AR style rifle or a while and a friend turned me on to RRA and I'm trying to decide between the LAR 8 .308 Varmint A4 (26" bull barrel") and the LAR 8 standard A4 (20" barrel w/muzzle break)..... I would like to hear yalls opinions of the pros and cons for both. I want the AR style with the range and knock down power of the .308. Where I live I'll probably never get a chance to fire beyond 400+ yards so would the standard A4 20" be adaquate uP to 400 yards or would I need the longer barreled version?
