Webley Raider Manual
The Webley Viper Venom is a precharged pneumatic legal limit air rifle in.22 calibre. This was one of the last rifles produced by Webley before going into receivership and in my opinion, one of the best made. It is basically a carbine version of the acclaimed Webley Raider, benefiting from a shorter Walther barrel, fitted with a silencing shroud. In use I found the silencing inefficient and modified the screwed in end cap on my lathe, to take a light weight plastic silencer. The report on firing is now inaudible beyond ten yards, which means more chance of a second shot. On one occasion, I had set out pigeon decoys, with sweet corn as bait to keep the birds on the ground and managed to shoot five from a down wind hide before they took flight.
This did highlight one deficiency of the Viper, a two shot shuttle magazine, which had me frantically feeding pellets, having to take my eyes off the pigeons, while I reloaded the shuttle. An upgrade was available later, a ten shot rotary magazine, intended for the Raider, fitting straight in, but the original set up worked OK for me. What ain’t broke, don’t fix it. Fitted with an inexpensive 9-3 x40 scope, the Viper accounted for over two hundred rabbits in my first year on a couple of infested farms. The rifle comes up to the shoulder easily and presents a steady shooting platform, allowing accurate kills out to thirty yards, while from rest, forty yard head shots were successful, although at that range a drop of three inches had to be allowed, when using Bisley Magnums.
This rifle operates on the precharged system. A pump, or on my case, a small diver’s bottle is used to deliver pressurised air through an inlet port to charge the air cylinder. A bolt is pulled back, carrying a spring loaded hammer with it, cocking the trigger and also the pellet probe is withdrawn, allowing the shuttle to align a pellet with the barrel. The bolt is then moved forward, the probe pushing the pellet in position ahead of the transfer port.
When the trigger is pulled, the spring loaded hammer is released, which pushes a valve forward, it’s drilling aligning with the transfer port, momentarily allowing air to pass at speed through the port, to enter the barrel behind the pellet. The probe seals the rear end of the barrel, so the pellet accelerates along the rifled barrel to it’s exit. Due to the light spring acting on the hammer, there is little mechanical noise and even less vibration, resulting in very accurate shots every time. The cylinder holds enough pressure for about forty shots. Hi Paul, I would suggest that the problem is that the O ring sealing the front end plug of the rifle has perished, which is allowing compressed air to escape out through the screw holes.
Sealing the allen screws with PTFE tape may be a quick fix, but you really need to take the rifle apart to renew the seals, as the rear end plug will also go soon too. I had to renew all the seals in my Career 707 last year and got them all cheaply from a plumbing supply shop. Do you have a manual? You can download one here.
It’s for the Raider from which the Viper was designed. Take off the stock before working on the rifle, this is done by removing the mid Posidrive and rear trigger guard Posidrive screw. You will need to remove the air probe first, then unscrew the CSK allen screw holding the barrel shroud inside the probe hole. This should allow you to remove the end cap. Then unscrew the three allen screws holding the front end plug in place. If the seal is perished badly, you may find the end plug will drop out, but you may need to tap the butt end of the cylinder with a nylon mallet, holding the action vertical to allow it to drop out of the end. I have worked on the hammer and bolt end of this rifle and it comes apart easily.
I have had my Viper from new and not needed to change the seals yet, the seals may still be available somewhere on line, but as suggested earlier your local plumber’s shop will have all you need. Let me know how you get on. It’s a good rifle and worth the work. Hi Joe, After I modified mine, I saw that Redbeck were selling the adapters on line for £15, but are now out of stock. I unscrewed my end cap from the shroud and measured the outside diameter of the thread at 17mm.To protect this thread, I turned up a thin split collet from aluminium, which just slid over the thread, but would grip it, when held in the chuck of my lathe (Myford Super 7). When gripped using this method, the cap ran very true.
I then opened out the cap, which is anodized aluminium, with gradual increases in drill size, until the tapping size of 11.5mm. I then tapped this hole in situ with a 1/2 inch x 20 TPI UNF tap. To make the spigot, I bought a 1/2 UNF screw, cut it down to 25mm long and in the lathe drilled a 7mm hole through it. This I screwed in the hole with a dab of locktite, leaving 12mm sticking out for the silencer. If you do not have the equipment, most small engineering shops would be happy to do it for pound notes. It’s worth the effort.

Webley Raider 10 Manual
OPERATING INSTRUCTIONS CHARGING THE RIFLE. Fit the filler nozzle to the air line of the charging equipment, which must incorporate a pressure gauge. Ensure both filler nozzle and rifle filler hole is clear from dirt, then push the nozzle into the filler hole. Fully charge the rifle to the cylinder pressure quoted previously in this manual. When using a divers bottle, refill the rifle slowly to prevent the heat created by the filling operation damaging the rifles components. Undo the hose air drain screw before pulling the filler nozzle out of the rifle. LOADING THE RIFLE AND USING THE MAGAZINE.
The design of the magazine allows the user to select their personal preference how it is loaded and used. To use the fast action Capability of the magazine to its greatest advantage, it is recommended the following procedure is adopted. Open the bolt and push the magazine fully to the right against its spring pressure. Close the bolt and load a pellet, nose first, into the exposed right- hand magazine chamber. Use the channel in the barrel housing to guide the pellet into the chamber and ensure the pellet skirt does not protrude from the magazine. The magazine 0 ring will retain the pellet in the chamber. NOTE THAT THIS OPERATION HAS ALSO COCKED THE TRIGGER MECHANISM / HAMMER ASSEMBLY AND IF THE TRIGGER IS PULLED AT THIS STAGE THE RIFLE WILL DISCHARGE, EVEN THOUGH THERE IS NO PELLET IN THE BARREL.
Open the bolt - the right hand magazine chamber is sprung into linemth the barrel chamber. Leave the bolt in the open (safe) slot position. Now load a pellet, nose first, into the exposed left hand magazine chamber as described above. DO NOT CLOSE THE BOLT UNTIL YOU ARE READY TO USE THE RIFLE. When ready to use the rifle, push the magazine to the right and fully close the bolt - the left hand pellet has now been pushed into the barrel and the rifle is ready to fire. Once the first pellet has been shot, open the bolt - the magazine will automatically position the second (right-hand) pellet in linemth the barrel bore. CLOSE THE BOLT ONLY IF YOU REQUIRE AN IMMEDIATE SECOND SHOT.
If you do not require a fast second shot, leave the bolt fully open and reload the empty magazine chamber. The firing process is now ready to be repeated.
NOTE ALWAYS ENSURE THE BOLT IS FULLY CLOSED BEFORE FIRING THE RIFLE. THE PERFORMANCE OF THE RIFLE WILL BE REDUCED IF THE BOLT IS NOT FULLY CLOSED. TRIGGER MECHANISM ADJUSTMENT The Webley Raider is fitted with a 2 stage trigger mechanism and is factory set.
The mechanism is adjustable if you wish to alter the factory settings. To adjust the trigger mechanism, the action must first be removed from the stock.
The diagram below shows the location of the trigger adjusting screws. A - lst STAGE TRIGGER ADJUSTMENT SCREW. B - SEAR ENGAGEMENT SCREW.(2nd STAGE TRIGGER ADJUSTMENT). C - SEAR ENGAGEMENT SCREW LOCKNUT. D - TRIGGER BLADE SCREW. PARTS LIST FOR WEBLEY RAIDER ADJUSTING THE POWER.
The mechanism of this rifle has been factory set to ensure its power falls within the current U.K. Maximum kinetic limit allowed without possessing a firearms certificate. The hammer adjustment screw is bonded to the hammer and any adjustments made will break the bond.
Unless rebonded the hammer spring compression may vary which will cause inconsistent power. If the bond is broken, consult Webley & Scott. DO NOT APPLY LUBRICATION TO THE AIR FILLER NOZZLE OR THE RIFLES'AIR FILLER HOLE. Use only mineral based oils such as 'Weboil' to lubricate the Raider. Occasionally apply oil sparingly to the following parts:- 1.The trigger mechanism - remove the stock for access. With the stock removed, apply oil to the rear of the hammer and hammer spring assembly through the trigger mechanism slot in the body tube. Close the bolt and apply oil through the cylinder bolt slot onto the bolt carrier.
Open and close the bolt several times. With the bolt open apply oil to the front of the hammer assembly. Apply oil to the magazine where it contacts the barrel housing assembly. Also apply oil in both magazine chambers, then cycle the magazine and bolt several times. This operation will lubricate the magazine chambers, the pellet prod and its 'O' ring. DO NOT OVER - LUBRICATE THE RIFLE. QUICK FILL NOZZLE'O'RINGS REPLACEMENT.
After a period of time it will be necessary to replace the 'O' rings on the Quick-fill nozzle. This YAII be apparent if compressed air is heard to leak from the nozzle during the filling process. Always replace both 'O' rings.
MAGASINE 'O'RING AND PELLET PROD 'O'RING REPLACEMENT. It is not necessary to empty the air charge from the rifle to undertake the following procedure.
If the bolt operation becomes stiff and lubricating the magazine assembly does not overcome the stiffness, the magazine'O ring, Part No 3289 may be worn where it is contacted by the pellets. Try to reposition the'O' ring so the pellets contact it in different sections. To remove the'O' ring, remove the 2 - magazine plate screws, Part No 3254 from the barrel housing, Part No 3224 and remove the magazine plate, Part No 3232. If your rifle is fifted with spacer washers between the magazine plate and barrel housing ensure they are refitted when the rifle is rebuilt.
Open the bolt and remove the magazine from the barrel assembly. Remove the magazine end cap screw, Part No 3271 and the magazine end cap, Part No 3231 from the magazine, Part No 3230. Take care not to lose the magazine return spring, part No 3300 which is housed in the top, front magazine slot.
Remove the old 'O' ring from the magazine. Check the slots in the magazine are clear of debris, lightly lubricate the replacement'O'ring, then fit the 'O' ring to the magazine. Do not overstretch the 'O' ring during the fitting operation. Reassemble the magazine assembly in the reverse order of dismantling.
Before refitting the magazine to the rifle, close the bolt sufficiently enough to reveal the pellet prod 'O' ring, Part No 3288, in the barrel housing magazine slot. If the 'O' ring is worn it may be replaced at this stage without the need to strip the rifle any further. Carefully cut the old seal off the pellet prod, Part No 3251, lightly lubricate the replacement'O' ring and push it over the pellet prod nose and into its slot. Refit the magazine assembly to the barrel housing, engage the magazine spring stop pin, Part No 3275 fitted in the magazine plate, with the free end of the magazine return spring and refit the magazine plate screws.

Once the rifle has been rebuilt, check that both the bolt and magazine cycles freely. USING THE WEBLEY PUMP TO REFILL THE WEBLEY RAIIDER. The Webley Stirrup Pump is supplied with a kit which allows it to be used with every pre-charged pneumatic air rifle currently available. When used with the Raider air rifle, the smaller 1 IS- adapter and face seal supplied in the kit are not required.
Fit the filler nozzle, supplied vath the Raider, directly to the pumps air hose assembly and tighten. Position the air hose/nozzle assembly so the rifle is lying flat on the ground when connected to the pump, then tighten the assembly onto the 1/4' BSP adapter. Use the appropriate tools to tighten all parts to ensure airtight seals. TO REFILL THE WEBLEY RAIDER ADOPT THE FOLLOWING PROCEDURE: 1. Close the pump air bleed screw, situated under the pressure gauge. Open the rifle's bolt.
Ensure there is no dirt in rifle's filler hole, situated under the muzzle, then lay the rifle on the gun bag or an old sheet placed on the ground. Push the filler nozzle into the filler hole and begin to refill the rifle.
The gauge reading will rise quickly for the first few cycles of the pump until the pressure in the air hose assembly is equal to that of the pressure in the rifle. As you continue to pump, the gauge reading will slowly rise as air is forced into the rifle's cylinder. Once the required pressure gauge reading is achieved, cease pumping. Release the air trapped in the air hose assembly by undoing the air bleed screw - the air will escape through the vent hole in the side of the base block and the pressure gauge reading will drop back to zero. Disconnect the filler nozzle from the rifle. The Raider is now ready for re-use.
