KA M4A1 Nylon Fiber Rifle with GHK GBB Kit

No, our gas airsoft rifles do not come with gas. We recommend that you take a look at the gas we recommend on this product page or see our gas cans under the accessories tab at the top of the page.

No, you must only use gas designed for airsoft or air guns. Yes, you will see videos on YouTube showing how to use other gas in your gun, but these have no lubricant and will damage your rifle beyond repair while voiding your warranty.

BB pellets are, simply put, the ammo your airsoft rifle will use. Choosing the right BBs can be just as important as selecting the right gun. This is because BB weight matters - this is simply how heavy the BB is. 0.20g is the most common weight of BBs, but 0.25g may give better accuracy.

If you are asking this question, the answer is yes: you must buy a blue rifle. If you are a newcomer to airsoft and have not attended an airsoft club or site, you will not currently be registered with UKARA. If you are over 18, you can purchase an Airsoft Two-Tone rifle. These blue guns are UK legal and comply with the VCR Act of 2007.

You must supply a defence at checkout to buy a RIF (Real Imitation Firearm) - a Black / Tan / Gold / Silver with no blue bits. Make sure one of the following is true: the delivery address is not in the UK, you have a current UKARA membership, you have a current UKAPA membership, you are a member of a properly insured historical re-enactment group or society, you are a film, television or theatre production company, you are (or are acting on behalf of) a museum, you are a Crown Servant in pursuance of your Crown duties.

FPS means ‘feet per second’ - a measure of velocity or distance travelled in a given second. So, in theory, the higher the FPS, the further the BB pellet will travel. However, you will also need to consider BB pellet weight and, importantly, if you are using a Hop-Up unit.

A Hop-Up makes it so that when a BB is fired from the airsoft gun, a small and grippy rubber pad rubs against the top of the BB. This has the effect of adding a backspin to the round projectile. Adding a backspin to any ball whilst flying through the air adds lift and therefore increases its range. Most high-end gas airsoft rifles have an adjustable hop-up so that you can set the gun for your optimal shooting distance.

Gas airsoft rifles perform best in warm weather conditions; however, if you plan on using this gas airsoft gun in cold weather, there are a few tricks worth keeping in mind. Also, please be aware there will always be a reduced performance in cold weather compared to a warm day. For more information, please see our blog.

If not well looked after, gas magazines can develop leakages in the O ring seals. However, there are some simple steps you can follow to prevent this: never empty the gas from the magazine - only do so by firing the gun and NOT by pressing the valve button on the mag; always store away with a bit of gas in the magazine to stop the seals from drying out; use gas with a high silicon content, and from time to time, use a repair gas with a very high falcon content. Failing these steps, you can always replace the magazine with a new one or replace the valves and seals at fault - it's a simple and cheap job.
