Dye & Proto Upgrades | DM Bolt Systems | DM4

The L7 Bolt System Upgrade for the DM4 takes accuracy, speed, and efficiency to a whole new level. The idea behind the L7 Bolt System is to reduce the moving mass inside the marker to the bare minimum. Lightening the bolt means that the marker will naturally have less kick/recoil and take less pressure and time to move the bolt back and forth. This means your marker will produce less vibration and recoil with each shot. This in turn allows you to stay on target better ....hence shoot more of your opponents.

Here is a customer testimonial video showing exactly what its like to shoot the L7 Bolt.

Many have said its best $80 you can spend on your marker.

Like to shoot fast? Who doesn't !?! The L7 will allow you to shoot faster and with more accuracy than you ever though possible. All L7 Bolts come highly polished and teflon coated, and designed with minimal o-ring drag enabling you to to have the fastest most consistent firing cycle possible.

Want your gun to be more quiet? Again, who doesn't? Its always fun be able to shoot at people when they have no idea where you are. The lowered operating pressure of the L7 Bolt naturally makes your gun cycle more quiet than any other bolt system.
