Frequently Asked Questions

Are 4UANTUM maintenance pens safe for rubber O-rings and plastic parts?

Yes. 4UANTUM lubricants are formulated with Polydimethylsiloxane and PTFE, making them 100% inert and non-toxic. They are specifically designed to be safe for all internal airsoft components, including plastic nozzles and rubber seals.

How many uses do I get out of one 4UANTUM Maintenance Pen?

Because of the precision brush tip, there is zero wastage. One pen typically contains enough high-performance lubricant to fully service a standard airsoft rifle approximately ten times.

Which 4UANTUM bucking do I need for my gun

For standard electric rifles, choose the AEG Friction Pro. For gas blowback pistols, rifles, or bolt-action snipers (VSR-10 style), you will need the GBB/VSR Friction Pro version. Both are designed to handle high-performance setups.
