Firearms maintenance guide
If properly lubricated and cleaned, a modern spring-piston air gun can achieve its maximum shooting potential and can be trouble-free for a long time. Ignoring this point will inevitably cause wear and tear on the gun, reduce its power and accuracy, and eventually completely damage it. Incorrect lubrication can also cause damage to the air gun and injure the shooter or bystanders.
Knowing the principles of maintenance will help increase the fun of shooting and help airsoft work. The following are the basic points of maintenance.
The air compression chamber is located at the front end of the bolt. When the air gun is fired, the piston advances in the air compression chamber to compress the air.
The sealing bowl of the piston must be kept moist with lubricant to reduce friction, produce the best sealing effect, and prevent deterioration and aging of the sealing bowl. When the air gun is fired, the instantaneous temperature in the compression chamber can be as high as 2000 degrees Fahrenheit.
Only lubricants with a very high spontaneous ignition point can be used in it. This feature basically eliminates the possibility that almost all petroleum-based and synthetic-based lubricants (used in firearms and pneumatic air guns) are used in the piston-compression chamber.
If these ordinary lubricants are used, they will be compression-ignited in the barrel and may damage the air gun and hurt the shooter. Only synthetic lubricating oil or carefully selected organic oil (vegetable oil-translator) with a high ignition point, appropriate lubricity and purity can be used in the piston-compression chamber system.
Commercial product lubricants that can be used in compression chambers include compression chamber lube, 9300 AirLube, or 9290 Ultra-Lube, recommended using the lubricating oil on the recoilless air gun). Compression chamber lubricants are rarely used.
Every 5,000 to 6,000 bullets or one or two drops of oil every eight to twelve months is sufficient. It is best to wait until you can hear the squeezing sound of the piston when pressing the spring before adding oil.
A little carelessness can easily over-lubricate. Recoilless spring-piston air guns, such as FWB300S style and 65 styles, require almost no lubrication. One or two drops of Beeman Super Lubricant are enough.
All lubricants should be used in small amounts as required. The shooter provides energy to the air gun through the compression spring. The mainspring is the storage room for storing this energy. In order to enable the mainspring to open smoothly with little friction and vibration, it should be regularly lubricated.
The mainspring is in the spring cylinder. The spring chamber (that is, the bolt housing-translator) is a polished tube that contains the piston, the mainspring, and the spring guide shaft. All metal springs eventually have scars, so the surface polishing and lubrication is the key to achieving the best performance. Simple but careful lubrication treatment can increase the rate of fire and the smoothness of firing of the air gun to a certain extent.
The spring oil is added from a long groove under the receiver through a filler pipe. You can see the long groove after removing the butt.
For the recoil spring-piston type air gun, five to ten boxes of ammunition (1250 to 2500 rounds), or the mainspring should be lubricated at least once every six months, and 2-3 drops of oil each time is sufficient. The springs of recoilless air guns require only occasional and very little lubrication.
The lubrication should be done by an authorized repair shop. The recoilless spring-piston air guns that are often used in competition activities should be maintained and overhauled once a year.
The use of Spring Gel 9295 or Mainspring Dampening Compound 9320 can greatly benefit ordinary recoil spring-piston air guns. If spring glue is used, do not use spring oil during the first 500-1000 rounds of bullets.
Very little spring oil can be used later. Beeman Metal-2-Metal 9130 is a molybdenum disulfide type solid lubricant with an excellent metal-to-metal surface lubrication effect and can penetrate into the main spring and spring Inside the metal surface of the interior wall.
Before using molybdenum disulfide lubricant (MOLY), the air gun should be disassembled by a qualified air gunner for cleaning. Beeman RX air gun uses air springs.
Therefore, the internal power system of the RX air gun must use Beeman super lubricating oil instead of ordinary spring oil (15,000-20,000 shots plus one drop of oil). Compression spring rods and linkage arms bear considerable pressure, and appropriate Lubrication guarantees smooth operation and minimal wear.
Molybdenum disulfide (MOLY) can also be used to lubricate the sliding connection area and compression spring connecting rod in Beeman/Webley Tempest and Hurricane air guns. Barrel pivot points and barrel detents can benefit From frequent lubrication.
Lubricant can be Beeman Ultra Lube or light polarized oil, don't use too much. Do not have lubricating oil with a low spontaneous ignition point around the sealing ring of the gun bore and the vent.
If necessary, some molybdenum disulfide (MOLY) lubricants can be used. The trigger assembly of spring-piston air guns is different in complexity, from the trigger of the cheap air gun with only two moving parts to the complex and refined trigger of the FWB300.
In most cases, molybdenum disulfide lubricants (molybdenum disulfide lubricants) should not be used on the trigger assembly (don’t try to lubricate the trigger system of a complicated recoilless air gun by yourself). You can apply a little bit of B30 on the trigger of an ordinary air gun to lubricating 9200 styles.
Barrel cleaning Since air guns do not use crossfire or primer, it is unnecessary to clean the barrel or barrel for rust prevention, but cleaning the barrel is essential to achieve good shooting accuracy.
The barrel must be cleaned and degreased. The oil residue is blown into the barrel from the compression chamber and the lead stuck on the wall of the barrel can greatly impair the accuracy of shooting (the barrel of an air gun generally does not have the problem of "sticky lead").
Most accuracy problems are caused by unclean barrels, which don’t even look dirty. If the air gun needs to be stored for a long time, clean the barrel first, and then apply a thin layer of MP-5 polarized oil No. 9205.
After cleaning the barrel with Beeman barrel cleaner and degreaser (Note: Never use the barrel cleaner of ordinary firearms, because these solvents may damage the air gun seals or cause compression ignition).
