Just finished my first .308 AR assembly. 20" barrel, midlength gas block. I purchased a DPMS 308 "compatible" gas tube. It just doesn't look long enough. It just clears the notch in the upper. It's installed right now but I'm not too sure about shooting it tomorrow. How far should it protrude into the Notched area (next to the charging handle slot)? I'm used to the tube extending half way into the notched area on an AR15. The 308 notch is at least twice the size of the AR15.
Any recommendations for the "correct tube"?
Thanks for any suggestions.
