Very cool pistol. Very good to excellent overall condition. Also worth noting is it was designed for left or right handed shooter, as the pistol grip will rotate to either side to accommodate ambidextrous operation.
THE BUSHMASTER WEAPONS SYSTEM. (1980s)
The Bushmaster weapons system was based on the function and operating principles of the patented DIP aircrew survival weapon designed at the United States Air Force Armament Laboratory at Eglin Air Force Base. Subsequent design changes integrated the battle proven characteristics of the U. S. military M16 and the unexcelled gas system of the Russian military AK-47; thus attaining the simplicity and functionality of the current Bushmaster production.
By consistently and methodically applying these principles, it has been possible to make a high percentage of all individual parts in the various weapons comprising the Bushmaster system identical and thus interchangeable both among our various models and with the Colt M16.
The overall concept of the U. S. M16 and Soviet AK-47 have been in military use for many years and both countries continue to produce these proven designs in large quantities. Along with these concepts, the utilization of all practicable new developments in the field of weapons technology, improved materials and the employments of the most advanced machine tools and special equipment insures that the shooter has at his disposal a weapon of .. sophisticated design and technology.
Shooter safety, reliability,even under punishing conditions, accuracy, simple handling and easy care and maintenance are the goals we have achieved.
The Bushmaster Pistol and Rifle are gas operated weapons available in Semiautomatic and Selective Fire (Semi and Full Automatic) models to qualified license holders.
The Bushmaster Rifle is available either with a fixed maple or a tubular nylon coated folding stock.
The fire control selector is located on the left side of the lower receiver. It is spring detented and locks in either two or three swivel positions, depending on the weapon model: Safe Semi-Automatic or Full Automatic.
The Bushmaster has been manufactured by Bushmaster Firearms, Inc. to meet our rigid specifications. We suggest that you read this operating manual completely, in order to familiarize yourself with the operation of your new gun. Please follow our recommendations to insure that you will enjoy many safe and pleasurable hours with your new Bushmaster.
The major difference between the Bushmaster and other pistols is that the pistol grip is forward of the magazine. A unique design feature, the patented swivel grip, allows the Bushmaster to be fired by both left and right-handed shooters.
The Bushmaster is fired by firmly gripping the pistol grip, grasping the receiver, and twisting the pistol so that while the pistol grip is vertical, the receiver twists 40 degrees right or left. For righthanded shooters the receiver rests on the riaht forearm, with the ejection port to the right. For the left-handed shooter, the opposite applies.
In order to swivel the Bushmaster, firmly grasp the pistol grip in one hand and the receiver in the other and “twist” the receiver in the desired direction.
In this position, the Bushmaster is now ready to fire.
SAFETY – PISTOL AND RIFLE
The Bushmaster is equipped with a selector switch safety. with the safety pushed completely to the right, and the arrow pointing toward the “S”, it is ‘impossible for the Bushmaster to fire. Push the selector switch to a vertical position, wit: the arrow pointing to the “F”, and the Bushmaster will fire one round at a time each time the trigger is pulled, until all rounds in the magazine and chamber have been discharged. It is suggested that the safety be kept the horizontal “Safe” position at all times when your Bushmasters not in use.
LOADING – PISTOL AND RIFLE
The Bushmaster is magazine fed and will accept 5-, 20- and 30- round: magazines.
To load your Bushmaster, be sure the safety switch is in the “Safe” position, and insert a loader magazine into the receiver, pushing firmly upward until the magazine locks in place.
To chamber a round, pull back sharply on the cocking handle, located on the left side of the receiver, and release it. The spring action of the operating rod will chamber the first round.
When the first round is discharged, the gas system will automatically force the operating rod rearward, ejecting the spent cartridge, and will chamber another round. Additional rounds will be chambered each time the gun is fired until all the cartridges in the magazine and chamber have been discharged. The operating rod will remain closed after firing the last round.
To remove a cartridge from the chamber, pull back sharply on the cocking handle. This rapid rearward pull of the operating rod will cause the live cartridge to leave the gun through the ejection port. As an added precaution, it is suggested that the chamber be visually inspected to insure that there are no live rounds left in your Bushmaster. This may be accomplished by pointing the Bushmaster in a safe direction, pulling the cocking handle all the way to the rear and looking into the chamber through the ejection port. When the inspection is completed, release the cocking handle and allow it to slide forward.
SIGHTING – PISTOL
Your Bushmaster pistol is equipped with a fixed front post and a windage adjustable “V” rear sight. Both are designed to be adjusted 40 degrees right or left, to accommodate the right or left-handed shooter.
SIGHTING – RIFLE
Your Bushmaster rifle is equipped with a windage adjustable quick-flip rear aperture and a protected elevation adjustable front post.
1) Remove the magazine.
2) Remove the “E” ring clip on the pivot pin located forward on the lower receiver just below the seam between the upper and lower receiver. with a round of ammunition, a ballpoint pen, or other small tapered object, press in, forcing the pivot pin and the rear take down pin to the left until they extend 1/2″. Pull the pivot pin as far as it will go. Now remove the lower receiver.
3) Remove the gas cylinder locking yoke by pulling back slightly on the cocking handle, pushing in on the spring retainer (toward the muzzle) and pulling it straight upward and off the gas tube.
4) Pull the cocking handle all the way to the rear, then pull it straight out of the receiver. Tilting the can slightly will allow the slide assembly to he removed from. the upper receiver.
To begin cleaning, take a 22 caliber cleaning rod and insert a patch in the barrel from the muzzle end, and run the patch back and forth several times. This should free the normal amount of powder residue in the barrel. If there is an excessive amount of powder residue, nitro solvent on a patch should be used. If there is still powder residue, a brass bore brush, dipped in nitro solvent, may be used. When the barrel has been completely cleaned, a clean patch dipped lightly in gun oil should be run through the barrel for preservation.
Next, the gas piston and operating spring should be wiped with a clean rag dipped first in nitro solvent, and then lightly dipped in gun oil for preservation. NOTE: IT IS IMPORTANT THAT THE GAS PISTON AND OPERATING SPRING BE KEPT CLEAN AFTER FIRING.
Next the bolt and firing pin assembly should be wiped clean with a rag dipped in nitro solvent and then wiped with a rag lightly dipped in gun oil.
Visual inspection of all other operating parts should be made and normal cleaning should be done.
The bolt and firing pin assembly may be cleaned from time to time, but need not be done more often than after each 1,000 rounds have been fired.
To clean the firing pin and bolt assembly, push the cotter pin from the rear of the firing pin assembly and then grasp the cotter pin and pull it from the bolt. This will free the firing Din which may be pulled toward the rear of the bolt. Then grasp the bolt cam, remove it from the bolt and pull the bolt from the bolt carrier. This will expose the major components of the bolt and firing pin assembly which may be wiped with a clean cloth dinned in nitro solvent and then wiped with a light film of oil for preservation. Reassembly of the firing pin, bolt, slide assembly and gas piston may be accomplished by repeating the steps listed above in the reverse order.
* Trip sear trip bar to allow hammer to come fully forward before closing lower receiver in order to avoid damage to fixed ejector.
THE OPERATING CYCLE (AUTOMATIC)
All models are fired from the closed bolt position. The following description is of the weapon with a cartridge in the chamber.
(1) Pulling the trigger rotates the sear and releases the hammer.
(2) The hammer strikes the firing pin and fires the cartridge.
(3) Gas pressure from the cartridge forces the operating rod and carrier rearward.
(4) The cam pin, following the cam in the carrier, rotates and unlocks the bolt.
(5) The case is extracted and the spring ejector ejects the spent cartridge through the opening in the ejection port.
(6) The action of the carrier moving rearward rotates the hammer downward to engage the automatic sear.’
(7) The forward travel of the operating mechanism engages the next cartridge in the magazine and chambers it.
(8) After locking and during the cam dwell, the sear release lever is moved forward by the carrier and releases the automatic sear, which in turn releases the hammer again.
(9) When the trigger is released, the disconnector rotates back to its original position and engages the hammer, stopping all action.
(10) In the Semi-automatic mode and on Semi-automatic model weapons the trigger must be pulled for each round that is fired.

SPECIFICATIONS – COMPONENTS
(1) UPPER AND LOWER RECEIVERS -
All BUSHMASTER lower receivers are machined from a single block of aircraft quality aluminum alloy and are black anodized finished. The upper receivers are steel alloy and are black oxide finished.
(2) BOLT CARRIER ASSEMBLY -
A precision ground cam pin and firing pin are used in conjunction with a seven (7) lug rotary bolt housed in a high strength steel alloy bolt carrier containing the locking cam. These components, as a unit, deliver the smooth, strong, lightning quick action found in the BUSHMASTER. The action is enclosed in a 1″ envelope. Bolt carrier travel for bolt locking is minimal, resulting in a compact, lightweight assembly .
(3) GAS SYSTEM -
The BUSHMASTER gas system starts with a steel alloy gas take off, which also acts as a front sight shroud. In the gas take off is a precision bored hole which accepts the stainless steel gas piston. Affixed to the gas piston is the stainless steel gas piston rod and an operating spring. The complete assembly travels back and forth during fire in the gas tube, a steel tube which acts as a precise supporting link from the gas take off to the upper receiver and as a protecting cover for the piston assembly.
(4) SLIDE ASSEMBLY-
The final link from the gas system to the Bolt Carrier Assembly is the Slide Assembly. The slide serves as an operating rod and acts as a guide for the operating spring, also serving as a charging handle prevents carrier rotation while actuating the carrier assembly. The slide is machined from solid steel alloy.
(5) BARREL -
All BUSHMASTER barrels are manufactured with the same precision and care that craftsmen gunsmiths through
out the world use in producing match and custom barrels. Precision turning and drilling, work hardeninq with hydraulic rolls, stress relieving after oil quench, (meaninq the barrel will shoot true no matter how hot it gets from repeated fire) numerous straightening operations before final reaming, and button rifling are some of the ingredients which make the business end of the BUSHMASTER RIFLE as lethal and accurate as its namesake.
