GHK are a high-end Taiwanese manufacturer of GBB rifles. The quality of their products is outstanding. If Real Sword were to make gas rifles, these would the very ones!

An unbelievable recoil from an ingeniously designed gas engine system, coupled with an unsurpassed gas efficiency make this a serious contender. As if that wasn't enough, the surface treatment makes this gun both rust and scratch resistant (I said resistant, not proof before someone tries! ;) )

Note: ONLY for use with 'hard' BBs! Do NOT use Bio or Blaster BBs as you can damage your hop unit!

- New HOP-UP system, ver 6.0 hammer and stable bolt lock.
- Steel made bolt carrier & CNC fishbone rail.
- The main receiver is made of aluminum die-casting, which is high precision, high stability and good strength.
- The stock is stronger and not easily broken.
- The bolt is made of impact-resistant material with a German made connect spring. It is flexible, not easy to break, but easy for removal and maintenance; which also saves gas due to its high airtight characteristic.
- The barrel has a very detail heat pattern, which is OEM by Montblanc. Steel thin-walled, light weight with a hollow center. The whole process of producing the barrel is almost the same level as the real gun.
- The inner barrel is a precision one at 6.03mm.
- Dilute phosphoric acid manganese as a surface treatment, which is double the cost compared to manganese. This makes the product rust proofed and scratch resistant.
- The gas consumption of M4 the magazine is better than the G5′s magazine. The M4 magazine can shooting 1 to 1/2 magazines in auto and 2 to 3 mags in semi auto.

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).
