This one was built a little bit back, after I had a 5" HK type barrel upper...tried it and thought it was too short. This one is 8 1/4" bbl and 9mm, uses the hammer that a normal rifle would(for those of you that understand that part). It has a spacer added inside the lower receiver extension so the bolt won't come back so far and shear off the bolt catch on an empty mag. The bolt for these is quite heavy by comparison if you've never handled one. There's a tungsten slug installed in the rear... The front tube is an NEA and the little front hook is quite comfortable for a front grip. It drops in between fingers...Information
