FWB Sport air rifle. This report covers Oil the rifle Some improvements over the 1. The spring was dry Velocity testing Crosman Premier lites Air Arms Falcon pellets H N Baracuda Match pellets Firing behavior after shooting In the futureToday, were going to try something recommended by Gene Salvino in the tech department of Pyramyd Air. He told me that its possible to quiet the new Feinwerkbau Sport air rifle by means of externally applied lubrication. In other words, no disassembly is required. That would be a huge plus to those shooters who dont want to disassemble their airguns. Oil the rifle. Genes recommendation is to use gear oil specifically 8. He said the mainsprings in several of the guns hes seen are very dry. Gear oil seems to be just the ticket to calm them down and get the rifles shooting smoothly. I removed the stock to get access to the cocking slot. Okay, thats some disassembly, but thats as far as were going. Feinwerkbau uses Torx screw heads for the 3 screws that have to be removed, and theyre all the same size. Once I found the right bit, it took less than 2 minutes to remove the 3 screws and separate the barreled action from the stock. This looks so similar to the FWB 1. Anyone who has disassembled a 1. The large bolt in front of the trigger holds the action together and is also the anchor for the front triggerguard screw. Some improvements over the 1. I see they used the general design of the FWB 1. Chernyshevsky What Is To Be Done Pdf Reader on this page. The first place Ill point out is the pivot bolt. It has a Torx head that allows you to tighten the pivot just enough. You want the barrel to remain in position after the rifle has been cocked. That keeps the breech as tight as it needs to be. The pivot bolt also has a Torx head. You can control the amount of pivot tension very precisely. On the right side of the breech, the pivot bolt nut is also Torx and fits into a recess in the end of the bolt. It spreads the bolt petals as its tightened, putting tension on the right side of the breech, while the bolt tensions the left side. This is an improvment over the 1. The pivot nut is also Torx and fits into a recess in the end of the bolt. Petals on the end of the bolt allow the nut to apply tension from the opposite side of the breech. You can also see in the picture above that the trigger blade is metal. This is another improvement FWB has made. They learned their lesson with the 1. Even though the trigger blade has no strain on it and will not break, shooters hate plastic triggers. The spring was dryAs Gene predicted, the Sports mainspring was dry. The synthetic spring guide another improvement over the 1. I wiped the spring coils with a cotton swab, confirming there was a thin film of moly grease on them, but it isnt enough to deaden vibration when there are any loose tolerances in the powerplant. And by loose, I means only a few thousandths of an inchMoly is used only on the mainspring and guide when the parts fit so tight we say theyre nailed together that means they must be forced together for assembly. The amount they used on this spring was too little to deaden any vibration. FWB needs to lube their powerplant more during assembly. The rear of the piston was coated with moly grease, which is correct. I left it in place but when I oiled the mainspring, I also put some oil on the back of the piston because Gene recommended it. Rear of the piston is well lubed with moly, but the mainspring is too dry. This is the gear oil I used  but as long as the lower viscosity number is 8. Oiling the mainspring. Dont use too much I let the oil move around the mainspring for 5 minutes, then put the action back into the stock. Next, I cocked and fired the rifle. The cocking stroke was far smoother and quieter than it had been before the gear oil. But the pivot bolt tension is still bang on, which means this Sport rifle is extremely well made. Other guns loosen with shots and have to be corrected a lot, but this one is holding exactly where it was when I took it out of the box. The shot cycle was now much smoother, but not entirely free from vibration. I shot it again several times, and it seemed to get smoother as I went. But it never got to the point of being vibration free. Gene suggested putting more oil in the action, but I looked and there seemed to be enough in there already. Maybe it just needs to be shot more to spread the oil around. Velocity testing Crosman Premier lites. Before the oil, the rifle averaged 8. Crosman Premier 7. The spread for 1. After oiling, Premier lites averaged 8. So there was a small drop in velocity and a small decrease in the spread. Air Arms Falcon pellets. Before oiling, the Falcon dome from Air Arms averaged 9. After oiling the average was 9. Slight loss of velocity and stability with oiling. H N Baracuda Match pellets. Before oiling, H N Baracuda Match pellets averaged 7. After oiling, the average was 7. This pellet did a little better after oiling. Firing behavior after shooting. The rifle still has a small bit of buzz, but its only about 1. I dont think itll get any better with time. In my opinion, the oiling method does work and for those who dont want to disassemble the rifle, this is a good option. The excess oil does run out of the gun, so be sure it doesnt drip onto furniture or the carpet. In the futurePyramyd Air has granted me permission to open up this rifle for you and look inside. I may do that after the 5. And I will then look at other things that can be done to tune the rifle even better.
