I think it would make a fine truck gun, but it is a little on the expensive side for that purpose, 'cause you need to have a handgun lower (Glock, 1911, etc.) for it. JMHO. I agree with Carne Frio on that. My preferences run to an old Win .30-30 with open sights for a truck gun.
An old AccuDot or ProPoint red dot scope works fine on the Mech Tech. I wrapped the flat steel skeleton stock in cold-weather peel-n-stick foam pipe wrap and zipped the fabric stock cover over that. The thruuummmm is gone.
Mine is for a 1911 and I loaded up some 230 gr ball and some 200 gr hollow points to .45 Super levels for it. 'Works fine. Minute of coffee cup at 50 yds and well within minute of dinner plate at 100 yds. Slow fire with a front bag, with an old cheap, blurry Tasco AccuDot. Springfield Mil Spec lower.
It's mostly for fun, but the appearance carries an intimidation factor if tacti-cool is what you're after.
