Filling related (5)

Can I use my shop compressor to fill my gun?

No.  Shop air compressors only produce 90 – 150 psi, the Slayer line of PCPs require 3,200-3,500 psi.  A HPA (high pressure air) fill system is required.

How many fills will I get from my tank?

The number of fills will depend on your tank capacity and pressure.  Check out this calculator by Lloyd Sikes.

How long will my gun hold pressure?

A PCP in proper working condition should hold pressure for months without a noticeable air loss.  It’s not unusual for PCPs to hold pressure for several years.

What is a fill system?

A fill system is the method used to charge your gun to the correct pressure, there are several options to choose from.  The most common are: tanks, hand pumps, specialized HPA compressors and industrial Nitrogen cylinders.

Tanks come in a variety of sizes and pressures.  The most important consideration is that the fill pressure of the tank must be  greater than the fill pressure of the gun.  You can not fill a 3,500 psi PCP with a 3,000 psi SCUBA tank, The appropriate tank would be 4,500 psi SCBA type.  4,500 psi tanks can be purchased from air gun retailers and fire supply shops.  They are refilled by dive, paintball and sporting good stores.

6,000 psi nitrogen bottles are available from industrial gas suppliers, these are available for sale or lease and will require a fill  adapter that fits the  CGA677  valve.  A regulated adapter is recommended.

Personal HPA compressors are now commonplace and allow you to fill your tanks or guns conveniently at home.  These compressors tend to be expensive but they do allow independence from fill stations which may difficult to find in some locations.

I have a leak, what should I do?

PCP airguns contain many o-ring seals; both static and dynamic.  These seals can deteriorate over time and may periodically require replacement.  We suggest you ship your airgun back to American Air Arms for service.

What is the warranty on your airguns?

All American Air Arms  airguns carry a One Year Warranty against faulty workmanship and defective materials.

If the airgun develops a defect within the warranty period, please contact us directly either by email or phone; do not attempt to remedy the problem yourself.  This warranty does not cover any damage caused by tampering or abuse to the airgun.

Our  airguns should only be disassembled by factory-authorized airsmiths.

If there is a need to disassemble any part of the airgun, please contact us first to prevent voiding your warranty and potential damage to the airgun and/or yourself.

Is your warranty transferable?

Yes, as long as the gun is still within the warranty period.  Customers purchasing used guns are encouraged to contact us to update our registry even if the gun is out of warranty.

How do I clear a double load?

The easiest method to clear a double load is to simply shoot it out into a safe backstop. If the bullets remain the barrel after attempting to shoot them out, you will need to tap them out with a wooden dowel. THIS REQUIRES DEGASSING THE GUN

What is the recommended barrel cleaning method?

Airguns shooting slugs will need regular cleaning.  Depending on lead/tin ratio used, cleaning may be required between 100-250 shots.

All Slayer rifles use chromemoly hammer forged barrels that may cleaned using a lead solvent and brass or bronze brush.  This is highly recommended over Goo-Gone or other friendly cleaners many times recommended for small bore pellet rifles.

Cleaning procedure:

  1. Make sure the gun is unloaded and there are no unfired rounds in the chamber!
  2. Place the gun upside down with the muzzle on a slight down slope in a secure gun caddy. (the gun is cleaned upside down to prevent any solvents from running down the transfer port and washing out the grease in the valve)
  3. Remove the Moderator, place the safety on safe, and cock the lever to allow access to the breech.
  4. Using a brass or bronze brush of the appropriate caliber, dip the brush in lead solvent (we use Shooter’s Choice),  tap against the jar to remove excess solvent, and make 10 to 20 full strokes through the bore.  Generally this is all the brushing that is required unless your barrel is badly fouled.
  5. Using a patch lightly dampened in solvent, run it through 4-5 full strokes.
  6. Run a dry patch through 1 or 2 strokes to dry the bore.
  7. Using a light, visually inspect the bore, if there are any spots of lead still attached to the bore repeat steps 4-6 again. (attached lead will appear as dark patches usually at the land/groove intersections an are most prevalent at the muzzle end)
  8.  If you are going to use the gun after cleaning you are finished.  If you are going to store the gun, we recommend 1 or 2 stroke of a patch coated in gun oil to prevent possible corrosion.
