You guys are stupid or something, the ones who gave it a one. It is a good gun and comes with all the upgrades you'll need. Plus it has a really good barrel with good accuracy.
Weaknesses:
It has funny welding around the verticle feed and it is a little hard to cock.The cocking is strait with little grooves so a pain there.
Conclusion:
I would definately recommend this gun to someone because it has all the stuff people pay lots of money for on other guns to upgrade. Overall I just like it and i have never had a problem with it. It is reliable and accurate with a 12" barrel. It is hard to find but you should look.
