Have used a shutter and tested other PMI, Spyders, etc.
Marker Setup:
Had the outlaw set with a 9v hopper, and a 12 inch carbon fiber barrel
Now I have a 01 autococker with nitro, the 9v revy and the carbon fiber with adapter
Recommended Upgrades:
The gun is a great gun stock, but a barrel could be a large improvement
Strengths:
Good trigger pull and rate of fire, good stock, nice wieght (little heavy, but adds stability)
Weaknesses:
Recoil is a major factor. The gun is powerful, but in a serious of bursts or rapid fire, hitting the same target, let alone a moving target, becomes challenge
Conclusion:
A good gun for the money and with the new line bruizers, you can get one cheap (I had the old pictured version), but If at all possible, go for a cocker. Its a much better gun.
