Spyder, Booyah ELCD Frame, ACI Exp. Chamber, Shocktech Rear Cocking Bolt, 14" Dye Aluminum Barrel, ACI High Volume Cell, Raised Sight Rail, Champ Sight, Gas-through Stock w/ Remote Line, 68cu PMI Pure Energy Tank
Strengths:
Makes the fps much more consistent therefore accuracy is improved.
Fits very nicely in your hand and the it can be twisted so that the hose will face the bottomline.
Weaknesses:
If you don't know exactly what you're doing when you install it, you may want to get someone who does to do it for you. Also, you have to buy an adapter seperate to fit into the gun. Atleast that's how it was for my Spyder BL.
Conclusion:
Good deal
A must if you plan on playing in cold weather with co2.
