Blue Freak Factory Impulse. Maxflow 4500 system, Freak kit, and I-frame
This setup rocks. It is fully adjustable. You can adjust foreplay, backplay and spring tension. The fame also is one piece. The trigger frame will no longer come loose from the solenoid housing. The fame is also milled and anodized making the frame apear part of the gun.
If you want the capability to shoot fast and have an adjustable trigger that looks sweet you need to invest in the I-Frame.
