You can find BB & Gas recommendations on the page below:

Do not use CO₂ magazines above 15 °C/59 °F.

To avoid parts wearing down prematurely or breaking, we recommend not using CO₂ magazines at all, as gas magazines deliver more than enough power.

First, please note that using the SSP28 with HPA will void the warranty, as per our warranty page.
Please use HPA at your discretion.

We do offer HPA options for the SSP28 here in our store.

Reducing wear on internal parts and preventing leaks can only be done by regularly maintaining your gun and magazines.

We recommend cleaning and maintaining your gun as often as you can, though here are our suggestions on how often is necessary to maintain consistent performance and prevent air leaks:

Cleaning of the inner barrel and bucking:

Ideally, the inner barrel should be cleaned after every game or usage, especially when used in adverse environments, such as sandy/dusty/dirty environments, or when used in rain.
To prevent accuracy issues or power drop, we recommend cleaning it every 3,000 – 5,000 shots.

Generally, cleaning the inner barrel should be done more frequently the smaller the inner diameter is (tight-bore barrels) and the longer the barrel is.

Maintaining the magazines:

There are a few things you should do after every game:

• Ensuring to leave a small amount of gas inside the magazine to keep the seals from drying out
• Cleaning any dust, dirt and other debris out of your magazine to keep it from getting onto the BBs and into the gun
• Checking that the magazine is not leaking anywhere – If it does, you will want to maintain it before storing it

Thorough magazine maintenance should be done every 3,000 – 4,000 shots to ensure that it does not start leaking, or if the magazine starts to leak before that.

You can find guides on magazine maintenance below:

Internal maintenance:

Maintaining the internal parts of the gun is recommended after 3,000 – 5,000 shots, though we recommend doing a light cleaning of the gun immediately if used in adverse conditions such as mud, sand, or dust: Everything that could prevent the gun from cycling properly.

Please ensure to follow our Academy videos closely when taking the gun apart for maintenance. Damage caused by forceful disassembly or incorrect assembly is not covered by the warranty.

What should I check when maintaining the internals?

• Clean and re-lubricate the slide/bolt assembly

• • Wipe down any old grease or oil from the slide/bolt and re-lubricate with lithium grease or light silicone oil
  • Repeat for guiding rails and other points of friction between the slide/bolt and the frame of the gun

• Inspect the nozzle and its return spring

• • Check for any wear and especially cracks on the nozzle, even tiny cracks can lead to a loss of power and gas efficiency
  • Clean the nozzle and blowback housing from any dirt or debris
  • Ensure that the recoil spring is not bent or overstretched

• Check the blowback unit

• • If the piston cup is dry, check for any cracks and keep it lubricated with silicone oil

• Verify trigger group functionality

• • Look for any wear on the sears, the hammer, and the valve knocker assembly
  • Clean off any dirt or grease and lubricate lightly with mechanics oil
  • Test for proper functionality of the trigger group, especially if the gun has full-auto capability

• Inspect internal screws and pins

• • Make sure that all internal screws are not damaged and tightened properly
  • Check if any body pins or internal pins are backing out or otherwise damaged

• Final function check and cleaning

1. • Clean any other parts of the body that get dirty over time, like the inside of the magazine well, the recoil spring assembly and other parts inside the body
   • Do a final inspection and check if the gun cycles properly and shoots well
