Unless otherwise stated in the Specification tab, Battery and Chargers are not suppplied.

Where supplied, Chinese batteries and chargers are warrantied to be not DOA (Dead on Arrival) only. We always recommend swapping out to a better quality battery and charger at the earliest opportunity.

Custom Painted products (Two-Tone) are non-refundable as these are painted to order. 

Unless otherwise stated, all products are sold singly.



Any figures used are based on tests performed on the products when they are first listed. These can vary due to changes by the manufacturer, gas pressure, gas used and a number of other factors. All figures should be treated as an approximate guide and used for reference only. 

All listed FPS are +/- 5% due to differences from rifle to rifle. If you require a guaranteed FPS, please add an upgrade/downgrade option on to your product (this may cost extra).
