There is nothing on the market that compares to this product.
Marker Setup:
Vision Impulse, Delrin Bolt from SP's, Volumizer by Toxic Toys, Kapp Gas-Thru Grip, "I" Frame, Delrin Valve, SS Hammer, Max-Flow 45/4500, Freak Barrel
Strengths:
John put alot of thought into this Frame. It takes the place of two parts on your stock Impulse, The grip frame and solenoid housing, Shortens the height by about 1/2 inch, and Moves the grip an inch forward to make the gun more balanced. The trigger is FULLY Adjustable, which is sweet. It has a blade trigger which feels good in combination with John's "humped" frame. Overall I think it is well worth the investment.
