This page describes the smaller features of the marker, and their compatibility with others.

Side Feed Port:
Shocker Sport bodies that aren't vertical feed are considered to be "side-feed". This includes both the stock right feed bodies that are most common, as well as powerfeed bodies. There's no difference between right feed and powerfeed, the only difference is the feed attachment itself (a straight tube for a right feed marker, or a powerfeed attachment for a powerfeed marker).
Side feed port types
Although the side-feed bodies are threaded to accept their respective feedtubes, they aren't really interchangeable with other markers.

Vertical Feed Port:
Vertical feednecks were introduced on Shocker Sports in the year 2000. At first (in 2000) they were unthreaded, meaning the feedneck was simply press-fitted in place, often held in position using a metal-to-metal epoxy. Later Shocker vertical feed bodies in 2001-2002 were threaded so the neck would be more easily removable. The threading on these bodies is the same as other SP markers excluding the Shocker NXT (this includes Impulse, Nerve, Ion, Epiphany, as well as Omen, Bushmaster, Piranha, and Invert).

Shocker Sport vertical feednecks were sized to fit the popular hoppers at the time, which was before Halos and eVolutions were released. These hoppers used larger feedstacks and it was only after they were released that markers started coming stock with feednecks sized for them. As a result, the stock high-rise feednecks on the Shocker Sport and Impulse were sized to fit Revvis and other agitators, as well as gravity-fed hoppers.
There are many aftermarket feednecks available, all of which will work on these model Shockers. However, there may be a clearance issue if you're using a Planet-milled body (or an Eclipse Shocker body), or if you're using one of the 2000 model unthreaded bodies. If this is the case then you'll need to choose a higher rise feedneck (such as a "mid-rise") or modify the body. One sample body mod is shown here:
Body clearance mod

Another possible mod is to use a lathe to trim the bottom of the feedneck itself. This will only work if the feedneck is just too low to fit. If you were to remove too much from the feedneck, it may weaken and break later on.

The barrel threading on a Shocker is the same as the Shocker SFT marker produced between 2003-2006. The current Shocker NXT marker (produced 2007 and later) is threaded differently. Typically, the threads used on the marker are known as Shocker barrel threads because the Shocker is the only marker threaded to accept them.
There are many aftermarket barrels available, both from SP and otherwise.

Ball Detents:
The ball detents are spring-loaded bearings designed to prevent double loading while the bolt is open. Only vertical feed Shockers are equipped with detents. Side-feed bodies aren't equipped with any anti-double loading device so it requires the bolt speed be timed correctly to prevent more than one ball from loading.
Vertical feed markers that have detents utilize one on each side of the body. These consist of a small, round housing that holds a spring and plastic bearing. The below picture is taken from a Shocker SFT so the breech looks a little different, but the detents are the same.

The Shocker Sport uses two short (non-Vision) detents. The detents can be removed for cleaning or replacement using a 1/8" allen wrench. Older detents from 2000 are removed using pliers. A common problem is for the ball to come out of the housing and get lost; when this occurs you will have to replace the detent (individual parts aren't available). Another common problem is for the detent allen wrench hex to strip out; if this occurs, use a hacksaw or rotary tool (dremel, etc) to notch a mark in the head so a flathead screwdriver can be used for removal.

SP ball detent threading is unique to SP markers, but there are a few aftermarket varieties available.
New Designz detents: Replacement metal detents made by NDZ. Higher tolerances mean these detents will be more reliable than the stock ones, and are available in multiple colors. Cost is $12 per detent.

Kila Magnetic Suspension v2 detents: Magnetic piston design, made to be impossible to "blow out" as a regular ball-based detent would. Features adjustable magnetic repulsion force. Rebuildable if necessary. High quality manufacturing makes these very good products. Cost is $25 per detent; available in multiple colors. Get them from

Eclipse ball detents: Wire-nubbin detents sporting the Eclipse logo. No longer available.
Hybrid detents: Piston based ball detents from Hybrid technologies.
Replacement stock detents cost $10 each.

Air Distribution Manifold:
The threaded gasline ports on the front and rear of the Shocker body mark the spots for the Shocker's air distribution manifold. The manifold is a long chamber that stretches the entire length of the body, through which air is delivered to the marker's internals. The air source can attach at either the front or rear of the manifold, which is threaded 1/8" NPT at both ends. One end of the manifold is for the air inlet; the other end of the manifold has to be plugged using a 1/8" NPT plug.

Located on the underside of the body are three additional 1/8" NPT plugs. The purpose of these is to seal off internal air passages required to supply pressure to the internals. These set screws don't need to be removed at any time unless their threadlocker seals break down (at which point you need only reinstall the plugs with a new coat of threadlocker).
Body set screws
There are two additional ports located on the underside of the body (about 1/16" diameter) but they don't need to be plugged. In fact, if they were plugged, the marker operation would be impaired.

Air Assist:
The small threaded port on the right side of the body (toward the rear) is called the Air Assist hole. When you fire, a small burst of air will come from this hole. The purpose of it is to attach a length of 1/8" LP hose (such as those found on an Autococker, Impulse, Ion, or other marker with hoses) and direct the air burst to the feedneck of the marker. This applies a small burst of air force onto the next ball loaded, helping to ensure a proper load each time.

The Air Assist port is threaded 10-32 so most standard fittings will attach. Please be aware that the Air Assist port shouldn't be plugged when unused. The Air Assist is actually exhaust from the bolt solenoid, so plugging it would prevent the bolt from cycling properly.

Firing Mode Switch Cover:
Markers equipped with a firing mode switch at the front (DS S/F boards or LS Turbo boards) can take advantage of a switch cover to prevent the switch from being directly shot during gameplay.

Shocker Sport S/Fs and Shocker Sport Turbos were supposed to come with the switch cover stock, however some did not. Additionally, there are two types of switch covers; one is a standard cover that allows you to reach through the bottom to adjust the switch, the other is a tournament lock that doesn't allow you to adjust the switch at all. In the above picture, the standard switch cover is shown (the underside of the switch cover is open to allow your finger to reach in).

Markers not equipped with an S/F or Turbo board come with a small rubber plug to seal off the firing mode switch hole in the circuit housing.
