  • Gas Blowback Rifle
  • High density polymer construction
  • Functional bolt lock, intense recoil

Do you have the need to feel thunderous recoil? Nothing will do it quite like a Gas Blowback rifle! The WE G39C gas blowback rifle operates just like the real thing, with a fully moving bolt carrier which cycles back violently with each shot. The G39C boasts full metal construction despite being made predominantly from high-density polymer and can be field stripped in seconds just like the real rifle.

GBBRs aren't for the faint of heart as this rifle feeds from 30rnd real capacity magazines and needs to be operated like a real rifle; requiring cocking to load the first round. When the mag runs dry, the bolt will lock back which is your cue to reload and hit the bolt release catch inside the trigger guard. No AEG can match the realism provided by a GBBR, and with its reputation for great performance and impressive cool-down resistance, the WE G39C is the perfect tool for the experienced Airsofter who likes a challenge. Consider this a GBB pistol on steroids!

  • Full metal construction
  • ZET System GBBR - TM compatible internals
  • Ferocious recoil, realistic handling  - Just awesome!

If you have a taste for realism, recoil and a new challenge in game, the Noveske N4 GBBR from EMG will give you what you need. This Gas Blowback Rifle boasts full metal construction, licenced Noveske trademarks and internals based on the best of the best when it comes to GBBRs; the Tokyo Marui ZET system. 

Not for the faint of heart or those who like to fight easy, a GBBR provides unparalleled realism with its realistic manual of arms involving loading the first round using the charging handle, counting your shots carefully due to low-cap magazines and taking your reloading skills to the next level thanks to its functional bolt lock. While a GBBR is a challenge to operate compared to a simple AEG, there is nothing that can touch a GBBR when it comes to its immersive firing experience and unparalleled realism. 

Licenced by Noveske through EMG and manufactured by Double Eagle, the N4 has absolutely gorgeous externals, with a thick, hard-wearing finish that looks phenomenal and showcases the crisply engraved Noveske trademarks which tie the whole piece together. The N4 GBBR also has a full steel trigger group pre-installed, saving you money down the line on essential longevity upgrades required to keep a GBBR running in the long term. If you have been holding out on a GBBR, waiting for something to pop up that has the right balance of affordability, efficiency and aftermarket support, now is the time!

  • Full metal construction
  • TM ZET System clone - Made by CGS
  • Licenced Daniel Defense trademarks from EMG

If you love the military look and like to dabble in GBBRs, the EMG CGS Daniel Defense DDMK18 GBBR should suit you perfectly. This full metal GBBR is licenced by Daniel Defense through EMG, boasting immaculate engraved trademarks across the design, and is based on the much-lauded Tokyo Marui ZET System internally, which is excellent news! 

The ZET system is widely regarded as the best GBBR internal system around, and CGS (CYMA Gas System) has made it even better, throwing in a generous complement of steel parts including the bolt carrier, trigger group and bolt catch. This means a longer lifespan than rival GBBRs and heavier recoil thanks to the added mass from the steel bolt carrier. Also inside is a 6.04mm tightbore inner barrel, a nice deal sweetener that improves gas efficiency and accuracy. If you've been weighing up getting into the GBBR game but the cost of fully upgrading a ZET System puts you off, this one has all the steel parts built in!

  • Shell Ejecting 
  • CO2 Gas Blowback Rifle
  • The most realistic Airsoft assault rifle on the market

Taking the concept of the ultra-realistic Gas Blowback rifle to the next level; The Rare Arms AR15 is powered by a CO2 bulb housed in the pistol grip, freeing up space in the magazine and allowing this system to eject a mock shell every time it is fired! The recoil on this rifle is something else, as is the feeling you get seeing a spent shell fly across the room. In terms of immersive firing experiences, this rifle is second to none. HPA Adaptor is now available separately

The polymer shells for these rifles are stated to be "disposable" by the manufacturer. They will likely last more than one use but they are not designed to be used forever and will need replacing after a certain number of cycles. This has been done to avoid the rifle's ejector and bolt being damaged with use, as they would be from metal shells.
