(3 out of 5) ATI 12 Gauge honest review
by from Sumte, SC on

The saying, you get what you pay for is very true, especially with weapons, but this is not a bad 12 gauge. I've shot with worse. The big issue I have encountered is, it does not eject 2-3/4 rounds. It does fine with the 3. Also, the buttstock is very cheap, I bought a tactical pistol grip for mine.
