NOTE: Eye protective devices designed specifically for paintball use must be worn by the operator and anyone within range.

Read this entire manual before loading, attaching a propellant source or in any way attempting to operate the BT-4TM.

Barrel Installation

Velocity Adjustment

Loader Installation

1. Make sure marker is degassed, hopper removed, no paintballs in the feed port or breech and the safety is set to "safe".
2. While pointing marker in a safe direction, place the threaded end of the barrel into the front opening of the marker body.
3. Turn the barrel clockwise until it stops (do not over tighten).
4. Adjust the barrel accessories if necessary. 5. Install a barrel blocking device. This can be a
barrel plug or other such device that prevents the accidental discharge of a paintball.

SAFETY OFF

Air Cylinder Installation

1. Make sure the barrel blocking device is properly installed and the marker safety is set to "safe" (red marking on safety will NOT be visible).
2. While pointing the marker in a safe direction, cock the marker by pulling the cocking knob located on the left side of the marker back until it clicks and stops.
3. Release the cocking knob. 4. The marker is now cocked. 5. Locate the air cylinder adapter. The BT-4TM
cylinder adapter is located at the base of the pistol grip. 6. Position the BT-4TM so that the air cylinder adapter is pointed upwards while keeping the muzzle of the marker pointed in a safe direction. 7. Insert the threaded cylinder valve end into the adapter. 8. Without pushing the cylinder, twist the cylinder clockwise and allow the threads to draw the cylinder into the marker until it stops. Your marker is now charged.

Proper Storage of the Marker When you are finished using the BT-4TM it is important that you prepare the marker for storage. This will not only serve to increase the life of the marker, but will assure optimum performance on your next outing.

Disassembly and Field Stripping
/!\ WARNING: Any assembly/ disassembly of any paintball marker should be performed by a qualified service technician.

Unloading

For S.W.A.T. or Banshee magazine expansion chamber removal instructions, please see page 8 prior to disassembly.

1. Put on an eye protective device designed specifically for paintball and make sure that anyone within range of the BT-4TM does the same.
2. Make sure the barrel blocking device is properly installed and the marker safety is set to "safe". 3. Loosen the loader clamping screw. 4. While holding the paintball hopper in place, invert the marker so that the hopper is below the
BT-4TM. 5. Remove the hopper and all paintballs. 6. While pointing the BT-4TM in a safe direction, remove the barrel blocking device and set the

Removing The Air Supply
1. Make sure the barrel blocking device is properly installed and the BT-4TM safety is set to "safe". 2. Point the BT-4TM in a safe direction and turn the cylinder counter clockwise about 3/4 of a turn.
This allows the cylinder valve to close without damaging the cylinder O-ring. 3. While pointing the BT-4TM in a safe direction, disengage the safety (set to "fire"). 4. Keeping the BT-4TM pointed in a safe direction, pull the trigger until the remaining CO2 or air is
expelled and it fails to re-cock. 5. Unscrew the cylinder from the BT-4TM. 6. The marker is now ready to be cleaned or put away for future use.

Note: If relocating, make sure marker is pointed in a safe direction, barrel blocking device is installed and safety is set to "safe".
1. Turn vertical foregrip retainer counter clockwise to allow retention pin to drop. A coin may be used to assist in turning the vertical foregrip retainer.
2. Slide foregrip to preferred location or remove if so desired. 3. Reverse process to replace foregrip.

Cleaning the marker Once the BT-4TM is unloaded and the air cylinder is removed, you can use a damp cloth to wipe off paint, oil, dirt and debris. You can also use warm water to rinse the marker clean. Once your marker is clean and dry you can re-oil using a light, premium marker oil. (Note: Petroleum based and aerosol products can damage your markers o-rings. DO NOT USE ANY PETROLEUM BASED OR AEROSOL PRODUCTS ON YOUR MARKER.) To access the rear bolt and linkage arm you must remove the left receiver half. (See marker disassembly section.)

Always store the marker in a secure location when not in use so as to prevent access by unauthorized persons.
Note that the retention pin must line up in a gap on the picatinny rail.

(01) Magazine Expansion Chamber

Not only does this add the look and feel of an M-16/M-4 magazine, it serves as an expansion chamber. This improves

the efficiency of your air source and allows CO2 room to expand into a gas instead of pushing liquid CO2 into the BT-4.
TM
The same expansion chamber characteristics often permit playing in lower temperature conditions. With the Magazine

Expansion Chamber, looks are certainly more than skin deep.

(02) BT-47 Barrel

AK-47 looks and feel make this one impressive looking, paint slinging machine. The AK-47 style barrel includes a

raised sight rail, faux gas line and hand grips. Don't be surprised if your opponents surrender out of fear alone.

Note: If the barrel comes loose and needs to be re-indexed, (sights or handgrips get out of alignment), you need to

loosen the set screws located at the base of the front sight and at the base of the ring holding the hand grips in place.

Twist the hand grip and sights as one unit until properly aligned and tighten the set screws.

(03) BT-M16 Apex Barrel

M-16/M4 looks with Apex performance. This barrel allows you to dial-in the back spin from zero to maximum and then

adjust the angle of attack from hard left to hard right to drop shot to maximum flat trajectory. Simply move the ramp

switch forward to increase back spin and then twist the Apex end to set the angle of attack. The BT-M16 Apex Barrel

looks great while providing, what some may consider, an unfair advantage.

Note: If the barrel comes loose and needs to be re-indexed, (sights or handgrips get out of alignment), you need to

loosen the set screws located at the base of the front sight and at the base of the ring holding the hand grips in place.

Twist the hand grip and sights as one unit until properly aligned and tighten the set screws.
TM
(04) Bi-Pod

This collapsible Bi-Pod can be adjusted for uneven ground and folded up when not in use. The Bi-Pod makes for a

stable shooting position preferred by snipers, the World over. The perfect addition to the Ironhorse, when every shot counts.

(05) Combat Stock

The Combat Stock gives you that great shoulder/stock support for optimal stability and balances out the BT-47 Apex Barrel.

(06) Collapsible "CAR" Stock

Collapse the stock for a short carbine style setup or extend it for a stable firing platform. By squeezing the locking tab

located below the stock and pulling or pushing the butt plate, you can adjust the length of the collapsible stock to

Reassembly
To reassemble the marker, reverse the Disassembly instructions starting with the barrel adapter, ball retainer and bolt removal. While reassembling the marker, you should oil all O-rings and sliding parts. All parts and o-rings returned to the marker should be free of debris and visual nicks and scratches which can alter the performance of the marker. All screws returned to the marker must be tightened so there is no chance of them vibrating loose.
Storage and Transportation
1. BT-4TM must be clear of all paint and propellant when not being used.
2. Be sure to have marker in "SAFE MODE" when not in use.
3. Make sure barrel blocking devise is in place.
4. Store BT-4TM and propellant in cool dry place.
5. Keep your BT-4TM away from children without proper supervision.
6. Your BT-4TM must be free of all paint and not attached to a propellant source while being transported to and from the playing field.
7. Observe and obey all local, state and federal laws concerning the transportation of paintball markers. For information concerning any of the laws in your area, contact your local law enforcement.

(01) Magazine Expansion Chamber Removal Using a 1/8" hex allen wrench, loosen and remove the two screws in the Air Source Adapter (ASA) to separate it from the trigger frame. Remove the screw in the upper right corner of the magazine expansion chamber using a 5/32" hex allen wrench. Remove this screw's nut stem by pushing through the hole with the 5/32" allen wrench. Grab the magazine expansion chamber by hand and pull straight down and out of its mounting collar. Remove the two slotted thumb screws at the top of the mounting collar and remove the dovetail plate. Then slide the mounting collar forward to separate it from the receiver.

(04) Bi-Pod Removal Loosen the large thumbscrew on the underside of the bipod to separate it from the barrel.

(05 & 06) Combat Stock and Collapsible "CAR" Stock Removal

These stocks take the place of the rear receiver. When servicing the marker internally, make sure the spring guide and bumper o-ring are in place when

reassembling, or else damage to the receiver may result.
