I've owned/had a number of short barreled .308 bolt guns. I had a M70 lightweight carbine for years, but traded it off after its accuracy fell off and I wasn't smart enough to fix it. Other .308s are a M600 Mohawk, a M700 stainless DM cut from 24" to 20", a Ruger American stainless compact, a TC venture compact, and also a Winchester M670 carbine in .30-06.
I like short barrel rifles for hunting in thickly wooded areas. They're handy in tree stands.
