Basic Points, Parts & Schematics

Overview

Basic points of of the airgun as well as a parts listing and schematic.

Basic Points:

The COMPRESSION CHAMBER is that portion of the receiver where the actual air compression takes place when the piston moves forward in shooting, since the air is heated to as high as 2,0000F for a fraction of a second upon firing, excessive lubrication will cause dieseling (detonation) that can possibly damage the airgun and injure the shooter.  Lubrication should be performed by technicians during regular service intervals.

 

MAINSPRINGS are the storehouses of the energy the shooter provides by cocking the airgun, and need to expand smoothly with as little friction and vibration as possible.  The mainspring is housed in the spring cylinder, which is a polished cylinder containing the piston, the mainspring, and the spring guide shaft.  All metal mainsprings eventually have some cant; therefore, the polish and lubrication of all surfaces here is critical for maximum performance.  Recoilless airguns receiving extensive use in competition should be services once a year by technicians.

 

COCKING LEVER LINKAGES receive considerable pressure; proper lubrication insures smooth operation and minimum wear.  Moly is also useful in such areas as the sliding parts.

 

BARREL PIVOT POINTS and detents benefit from lubrication.  Remember; do not over lube, and keep low flash point oils away from air vent and breech seal.

 

Front and rear STOCK SCREWS must be firmly tightened and checked before each use of your air rifle.  If loosening occurs, remove stock screws, degrease stock screws and stock screw holes thoroughly; then sparingly apply Loc-Tite 242 (blue) sealant, and tighten firmly.

 

BORE CLEANING. Since airguns do not use powder or primers, cleaning is not necessary to prevent most rust; however, it is essential to good accuracy.  Accuracy suffers badly due to caked grease residues blown into the bore from the compression chamber and from leading.  Most accuracy complaints are the result of dirty bores-even though they may look clean!  for storage, clean the bore and leave it with a light coating of CLP (Cleaner, Lubricant, Protectant) oil.  After cleaning with CLP oil (do NOT use regular firearm bored cleaners as they will damage seals and cause dieseling), follow with dry patches until no trace of oil is seen.  A few regular pellets will have to be shot through a cleaned barrel before it can be expected to return to its "zero".

 

EXTERIOR SURFACE should be regularly wiped with a silicone cloth to maintain the quality of the finish.  before airguns are stored, they should be given a good wiping with a very high-grade polarizing oil.

 

USE PROPER PELLETS! Use only high quality pellets to avoid harmful oils, abrasive material and airgun barrel damage.  Precision adult airguns are intended for use only with lead, or non-lead alloy pellets.  Steel shot or darts damage air rifle bores.  Properly seated pellets should not show rub marks on rear of skirt if breech is reopened prior to firing.  damaged, used or unauthorized projectiles may cause dangerous ricochet, excessive piston impact and excessive penetration.

 

ACCURACY TESTING. The accuracy of the airgun will only become consistent once barrel and cylinder are fully bedded in.  This usually takes approximately 1000-1500 shots, this applies to open sights or being used with telescopic sights.  high consistent accuracy can only be achieved if the rifle is correctly zeroed in with an appropriate scope and mount system and shot from a bench rested position.
