Actually the 5 barrel is a thought as i have 10 barrels and 2 pcs of brass round stock. I'm somewhat intimidated by the bolt(s) construction and if push comes to shove and i have to buy them from some one at $50-60 each or more, be easier to afford 5-6 better than 10. I want to build a safe, shootable gun, not a show piece. The lack of affordable bulk ammo makes me question the wisdom of building a serious ammo eater. The days of $10.00 for 550Rnd box at Wally World are gone.
