Yes I have one and it has ran any type and
grain ammo I have fed it. I put a red dot on it and shoot a steel plate rack at 35 to 50 yards and it is a blast. Have fired 300 + rounds with no failures at all. Only complaint is its a little bit heavy, but fun.
Like Mini 14 Heavy?
Yes, with out looking up the specs it does feel like a mini 14 in your hands. And back by the same great customer service.
