Excellent workmanship and fun to own. Disappointed that the moderator barrel would not fit on the earlier models – which is why I bought the second one and that 1/2 by 28 threads seem a bit odd and will not fit all 1/2×28 adapters. Wish early one had more ammo storage but this is part of product development and response to customer needs. Overall very satisfied. Next they need to get a magnetic tru-glo type fiber sight (like a shotgun rail one) to sit on top of the barrel. Send one for free if you use my idea!!
