SYSTEMA¡Çs methodology in our pursuit of precision for our P.T.W.

(An introduction to a component of our P.T.W. barrel assembly)

As an airgun is similar in design as a real firearm, one of the most important factors in performance is accuracy. When used outdoors, this performance of ¡Èprecision¡É is greatly affected by various factors making it very difficult to measure in detail. As opposed to a real firearm due to the short range of an airgun it is possible to obtain measurements by testing indoors and thus make minute adjustments; on the other hand due to the relatively low discharge energy it becomes more difficult to pinpoint the problem.

At this time we would like to introduce our new P.T.W. Barrel Assembly as well as explain our methodology in our pursuit in improving accuracy (precision).

In particular, we looked into many physical factors to improve performance and in our research we wanted to focus on accuracy.

1. The precision of the BB when used.

When discussing this topic, focusing on the dynamics of the BB is unavoidable. Although our BB¡Çs are mass produced we are able to maintain very strict control, therefore we can say that there is only a minor deviation to our BB production. In standard production BB¡Çs the primary ingredient of Barium is coated with 20% resin through injection molding; is then reduced through an abrasion and polishing process, which is then packaged and shipped out. Due to the mass production of this cheap process with simple materials it requires mass quantities of molds; these molds in turn create parting lines which require an extensive abrasion process to remove hence we see many of our competitor¡Çs BB¡Çs where the outer diameter is smaller than they claim.

In the principle of hydrodynamics it is said that it is more favorable to have a smaller spherical plane for better performance, however as it is not possible to completely maintain an airtight seal prior to discharge we feel that the weight of the BB from the portion of the abrasion process becomes more important in affecting performance. For a very long time we have used the .2gram BB as the foundation of measurement from a safety standpoint. Other than for the purposes of Game Skirmishes or for training we recommend the use of 0.25gram BB¡Çs. The true performance of the P.T.W. can be experienced with this weighted BB. Although we digress, when we test the accuracy of our P.T.W. we also test our BB¡Çs as we would like to explain below.

Method of inspection of the BB¡Çs

­¡ Testing the Outer Diameter

Of 5 rounds each must not deviate beyond 1/100mm

­¢ Inspection of the entry point of the gate

Out of the 5 rounds tested inspect all five resin pour entry points from the gate paying attention to the abrasion process using a magnifying loupe.

­£ Measuring the weights of a 100 rounds

Measuring the weight of 100 rounds with no more than a discrepancy of 1/100gram.

­¤ Overall Finish

Confirming the overall finish of the test 5 rounds.

2. The Barrel Component

Of all of the components that make up a rifle the barrel has the greatest influence in accuracy. In the world of Airguns it seems to be believed that the inner barrel (which directly contacts the BB) is the only thing that influences accuracy. However we like to believe scientifically that it is the comprehensive integration of the Outer Barrel and the Chamber (which makes up the assembly) that influences accuracy. One example would be the vibration condition of the barrel assembly. For the P.T.W. the vibration that emanates as the Piston cycles causes the inner barrel to vibrate while the second (and subsequent) BB¡Çs traverse, we suppose that has some influence in affecting precision; with the gap between the inner and outer barrels are minimized increases the surface contact we theorize that the vibration in the inner barrel is decreased hence increasing precision. In doing so, will improve precision especially in regards to full auto fire. In addition, in order to realize this special setup and to create these components require a tremendous level of technical expertise and inventiveness.

a) Outer Barrel

The Outer Barrel is processed out of a single steel tube pushed out through oil and cut using a CNC Lathe to a dimension of 32mm O.D. 10mm I.D., with 11mm of meat in between. Most notably in the process of pushing out the molded steel tubes it is common to see variances in Inner and Outer Diameters therefore it is important to process both sides evenly using the NC (numeric control) Lathe. In a normal lathe process excess material from the outer portion is shaved away. However with this method the variance of the central portion of the inner and outer diameters are not dealt with. Therefore, even if the inner barrel can be inserted into the outer barrel due to minute differences in the central part of the chamber (in a worst case scenario) would not allow the inner barrel through completely. It would be safe to assume that with the differences in the basic dimensions of the barrel that one could not expect to hit with precision. On the other hand, processing with both central portions as the origin; minute differences would not occur thus alleviating that problem. Furthermore, the design of our outer barrel processing system allows us to always receive a perfectly finished barrel once it is completed through this automated process. Therefore, in the second as well as during the third stage installation process one will not encounter any gaps; one can consistently experience the precise and superior dimensions of the barrel even when undergoing maintenance.

b) Inner Barrel

As opposed to the push through method in creating our outer barrels, our inner barrel manufacturing requires an extraction method which we require a higher degree of precision. As stated earlier the components used in our barrels must meet a specified weight to every 12mm of inner barrel of material. However, as the process required more material maintaining the inner dimensions we changed the specified weight to every 10mm of material. We used our experience from our design of our custom Marui inner barrels in production of our P.T.W. barrel; hence it was significantly easy to develop. As in our previous experience, we avoid application of heat treatments nor do we apply any plating; we also take extreme measure to ensure a thorough processing and safekeeping of our materials. The only difference between our production of the Marui custom barrels and for our P.T.W. inner barrels would be for each P.T.W. barrel we process they must be customized to each outer barrel therefore each and every barrel is custom adjusted using our center less abrasion and polishing process for a perfect fit. Regardless of strict measurements due to the materials used in the outer barrel it is often difficult to maintain a set measurement therefore when putting together the outer and inner barrels we must use between 4 to 6 different barrels of varying pitches each with a pitch tolerance of no more than 0.05mm. It is due to this reason that the inner and outer barrels are sold as one set; it is not possible to simply change out an inner barrel without any complications. Even if our customers simply wish to exchange the inner barrel we cannot do so as it is because of this reason that we ship out the barrels as one complete set (and not the inner barrel exclusively). We appreciate your understanding in our methodology for our pursuit of precision.

c) The structure of the Chamber

As the nozzle loads the BB during the short period of time awaiting the propulsion of the round the Chamber (in particular the Chamber Packing) has a great influence in governing accuracy. With our unique ¡ÈDirect Loading System¡É even during an improper discharge the recoil from the main spring pushes the piston head through thus moving the nozzle which in turn makes it very difficult to damage the main gears (which is a strong point); however if this occurs it is difficult for the BB to remain in the standby position in the chamber packing (which is one of our weak points). In order to make up for that weak point, not only is the chamber packing but the hop packing requires extensive enhancements that are exclusively our design.

3. The structure of the HOP

a) HOP Trajectory

By introducing spin to the BB it adds lift to the round during flight which is considered a very general concept at this time. However during a game what should occur with the round is a parabolic orbit as the round spins and lifts; some accuracy is sacrificed in exchange for that slight bit more distance; simple desire to get maximum range in this context would require significant amount of time to perfect.

In addition, to maintain the direction of spin the correct position of the rifle would be required; firing the rifle in a downward angle would require significant training and may be one of the main obstacles that needs facing.

b) Our thought into the creation of our HOP

By using the 0.2gram BB we are able to test for accuracy with the maximum trajectory range of 30meters while maintaining a safe environment. Therefore, instead of focusing our attention on developing a reinforcement based on various situations we wish to focus on the Hop portion when the BB builds pressure and the downward spin upon discharge. The purpose of our P.T.W. HOP adjustment screw was not developed to control BB flight trajectory nor to adjust for the variances in BB weight; but it was designed to be able to allow for the differences in the BB production lots and able to make fine adjustments to allow for slight differences in the outer diameter.

4. Performance found in the Cylinder Unit

a) Power and Trajectory

Have you experienced difficulties in getting accuracy out of the 0.2g BB which is 20% lighter and considered the mainstream round? We concluded that accuracy and maximum trajectory can be achieved through power. Although it may appear to sound like a dangerous notion, it is quite a different reality. Of course when measuring muzzle velocity, it goes without saying that within a short distance the energy generated from powerful muzzle velocity can be very dangerous. However as the round surpass the distance between 10~20meters the discharged energy stemming from the use of lightweight BB¡Çs is overall poor. In contrast, with the use of heavier weighted BB¡Çs the loss of power as it traverses through the air is minimal, thus is considered a more dangerous round. On the other hand, with the same concept for a lightweight BB as the energy (that pushes forward) begins to weaken accuracy is affected. In other words, it is important to maintain the forward momentum energy while lengthening the distance to target. This is the reason why we insist upon the study and development of ways to maintain power with the use lightweight BB¡Çs. The P.T.W. has been developed primarily as a training tool therefore the distance to target is adjusted according to the training situation. This is the reason why the cylinder unit is adjustable to suit the trainer¡Çs needs. In order to deal with this specific need; easy take down and simple switching out of the cylinder unit is possible resulting in a revolutionary and safe design.

b) Stabilization of the muzzle velocity

Poor precision can be attributed to deviations between the vertical and horizontal tick marks from the sights to the target¡Çs actual impact point. When firing from a bench rest the skills of the shooter is in less of a demand (as opposed to non-bench rest shooting), at which point any horizontal deviations (left or right) may be attributed to either poor workmanship in installation of the barrel or poor barrel craftsmanship. In contrast, any vertical deviations (up and down) from bench rest firing in our opinion could be attributed to the power of the BB discharge. In other words, a rifle with a steady muzzle velocity would yield a high probability of accuracy. The culmination of all of our experience lives in our P.T.W. Cylinder Unit. Everything from the lead valve, piston head, compression main O-ring, as well as the internal workings of the cylinder and even to the know how of the proper lubrication; has seen splendid achievements upon development in each area. Even with the disadvantageous notion of a removable cylinder unit we are able to maintain a safe muzzle velocity record of ¡Þ2m / sec. is hard to determine the impact point deviation from the perspective of the shooter. However when it comes to accuracy it has a very big influence.

In conclusion, we chronicled our pursuit of precision and our methodology that lead to our culmination of our research and development. We feel that it is common sense in our procedure of development; because in this way we are able to understand our purpose and to achieve our goals we think of our methodology, come up with detailed plans, make prototypes, inspect and analyze our prototypes that way we can achieve our goals. When we first started out we focused on what would be considered the true test for any manufacturer (custom upgrade parts) and we are able to continue to this day. All of our knowledge and experience in development of custom upgrade parts gave birth to our P.T.W.
