Manufacturers will, in the main, supply the rifle with a filling adaptor which needs to be attached to the air line. There is very little standardisation of valve design, however, so most manufacturers will have their own design of adaptor. When you can clearly see the needle on the air gauge, open the main valve slowly, taking care to close the valve when you’ve reached the desired fill pressure. You’ll also need to open the bleed valve before your can remove the air fill line, as this will still be under pressure, even with the main valve closed Getting your cylinder ready for a refill

If the gun is intended for hunting or general target shooting, the manufacturer’s recommended fill pressure, which should offer a pleasingly large shot count, must be adhered to. Obviously the pressure inside your charging cylinder will fall every time you fill your gun. When the pressure drops too low, you’ll need to take the cylinder to the dive shop so it can be refilled. It’s worth ringing ahead to book it in. For owners of several PCP airguns this can be frustrating as constantly unscrewing adaptors from cables and adding different ones is not only time-consuming, but may lead to air leaks, with threads becoming worn or dirty.

Most PCP airgunners wonder about how many fills they will get from their cylinder. It depends on a few things: the capacity of the cylinder, the pressure to which it’s been filled, the size of the air cylinder on the air rifle, the pressure to which that can be filled, the efficiency of the rifle and how many shots have been taken before refilling. Owning a PCP airgun means additional cost compared with other types of airgun since charging gear will be needed, be it a dedicated pump or air bottle. If you take the high-pressure air bottle route then safely store it well away from children. We have a team of expert technicians and a complete repair shop that are able to service a large variety of brands/models of airguns.

If you live in a state or city where air guns are treated as firearms you may be able to take advantage of our FFL special program. Don’t f ill your rifle to a higher pressure than the manufacturer recommends. You won’t get any more shots and you could damage your gun. Fill Limit We’re talking ‘sweet spot’ here – a term which has entered airgun parlance and refers to the fill pressure at which a particular gun will produce the longest string of super-consistent shots.

Safety check for fill probe valve

Take care to keep the air fill line hose as straight as possible – this helps airflow and minimises strain on the components A warranty is provided by each manufacturer to ensure that your product is free of defect in both materials and workmanship. This could cause the first 15-20 shots to be lower powered until the residual pressure drops to 170bar. At this point the string of 65 consistent shots will be produced before the velocities drop off in the normal way. With a non-regulated airgun it’s a different ball game. The Air Arms S400 is a classic example of a non-regulated PCP. Air Arms quotes a fill pressure of 190bar, yet while you can fill to that pressure it’s likely the action will benefit from a lower initial fill pressure if ultimate consistency is required for competition use.

Lay the cylinder on its side for both storage and filling to prevent damage. Think beforehand about where you’re going to place your rifle, making note of the orientation and angle of the fill port. BSA Fill Probe ( R10 / T10, Scorpion, Sportsman & Ultra) - 1/8" BSP Male Thread, With Spare Seals & Lube The dive shop cylinder itself is massive and filled by a compressor. One shop I used to go to would only refill its cylinder when the pressure was down to 240 bar, as the staff didn’t like firing up the compressor any more than they had to. Think about the length of the hose you’ll need. A longer hose gives you more space to manoeuvre and you are less likely to bend the hose, which should be avoided whenever possible. Filling a PCP air rifle For HFT/FT enthusiasts and hunters who want to maximise and fine-tune performance, some judicious trial and error testing using a chronograph on the range will be time well spent.It's important to know that due to state and local laws, there are certain restrictions for various products.
