Would this be a good and cheap alternative to the P-90?

The AR57 rifle is designed for use in any climate and ready for the most extreme use you can give it. Sand and mud will normally clog and jam most rifles and carbines yet have very little effect on the AR57 due to its simplicity and strength. The AR57 is more than a challenge to any SMG, carbine or military rifle in the areas of accuracy, ergonomics, reliability and durability.
Designed as a upper that can be attached to any M16/AR15 lower, it is not dependent on the lower for reliability of ejection or accuracy. The AR57 features ambidextrous cocking handle and magazine release levers with brass ejection out the bottom of the magazine well. The barrel is free floating for improved accuracy and includes a standard M16 flash hider.
