PROS: This is the BEST spring shotty for the price I have ever seen, this thing hurts like hell up to 75ft away, it will leave welts, any closer and your risking broken skin. it is well built, heavy, metal barrel, heavy PVC plastic stock, body, adjustable hop up, rubber buttpad, very nice swivel shoulder strap brackets.
CONS: needs a bigger mag, better hopup, iron sights would be nice, but not necessary.
what I would change: not much, this is a very solid shotty for the price, I would add a bigger mag, and a front bead sight.
Definitely recommend this, and also recommend AirRattle.com
