After the M2 Heavy Barrell,, and I mean heavy.. I know as I lugged one to the track park with all my ta-50 gear many times. I still feel a creek in my back.. and beside the 1911.. for civilain shooters.. / deer rifles.. I love my Acera. Straight pull bolt action,, Accurate and very rare. Have never seen one except for mine in person.. I seem to have the only one in the world ,, well at least ,, Maine..
