About this section:

The H.E. bolt has become a new standard for many players who use the shocker from the Philidelphia based company Smart Parts. While the intial success of the shocker provided overwelming support the only flaw that left a bad taste for many players was the bad efficiency. The company listened to the players and came up with they called the High Efficiency bolt. The recommended increase from around 900 shots to about 1200-1400 shots will definetly provide the extra bang for your buck. Our testing showed an average of 30% decrease in gas usage. Other aftermarket shocker bolts like V2 bolt by Evolve paintball can produce results in excess of 1800 rounds on a single fill. Evolve also has produced a second version of their bolt which they call the U.L.P. bolt. The ultra low pressure bolt will allow the shocker to cycle a much lower pressure and will allow a net effect of increased efficiency and an added bonus of less wear on the the guide and internal ram.

To install one of these bolts we will need to know if it will fit the inside the body shaft (described above); the Private Laber shockers tend to have different shaft sizes then their stock style counterparts. Luckily if you purchase the Smart Parts H.E bolt it comes in a kit with bolt, guide and shaft which makes it less difficult to get a proper fit. First you will want to use a 3/16 allen key and unscrew the aluminum bolt cover on the back of the marker. You'll need to slide the old bolt and guide/chamber assembly out, which you can do with one simple motion. Next take the o-rings (the number of o-rings is different on various kits) and arrange them in the groves on the bolt. Then take the bolt and place it within the guide, place the guide within the chamber and slide the chamber and all (3 or 4) pieces in the shocker body. From there all we will need to do is adjust the dwell on the board. It is easiest to start at the bottom of the dwell (also we'll need to have an much lower input pressure - around 160-190psi). Slowly increase the dwell by 2 or 3 clicks up until the marker cycles completely, if you encounter shootdown adjust the dwell down by 1 click until you notice no kick. Finally let on the gas and adjust the input pressure until you reach the velocity you want to play with.
