Nobody here has said that these battle rifles are unshootable due to their recoil, just they have a hefty kick. I know someone personally who has shot an AR-15/M16 for 20 years who shot my M24/47 two weeks ago. It really startled him, and he's a medium-large guy. I then handed him my M91/38. He loved it, but was definitely rubbing his shoulder after five rounds. I then told him next time we'll try my M95.
Those of who are telling us to 'man-up' or 'grow a pair' may not realize that everyone handles recoil differently due to experience, body size, weight, etc. I happen to like the kick of these rifles, but that doesn't mean I can tolerate 100 rounds of it in one afternoon.
