You could do better for the $400. That rifle has a habit of hanging up, failing to cycle and sometimes really jamming up, like having to bang a jammed round out. The gas system is easy to manufacture and cheap. The fire control mechanism (trigger group) is, well, cheap. It uses sheet stock stamped parts. Yea, I know, they don't kick, they are good for "spray and pray" style hunting and everybody has an uncle who killed a big buck with one - they sold many, many of them.
If you are bent on a semi-auto, go with the BAR, even though they are more money. For "fast follow-up (?) shot repeaters the Remeington pumps are ok, especially after they went with fewer and larger lockin lugs and the Browning pump is even better. The Browning BLR is excellent.
There are many 4s and 7400s out there but more than one camp has heard the "my 4 won't shoot no more" crying in the middle of deer hunting.
