  • Full metal construction
  • 5/10 BBs per shot - Deadly!

If you’ve seen our videos from IWA and the G&G World Cup you must be lusting after this thing as much as we are! Introducing the G&G Armament ESG-B10 Gas Shotgun, the spiritual successor to the ill-fated FLAK-12 design, a semi-automatic gas-powered shotgun offering the choice between a punishing 5 BBs per trigger pull and a positively evil 10 BBs!

The ESG-B10 is constructed with a CNC Aluminium upper receiver and a superb quality high-density polymer lower, as G&G is known for, and takes standard M4/AR-15 AEG magazines, meaning spares are ever available. Bristling with M-LOK slots on each side and the bottom with a generously long 20mm Picatinny top rail, the ESG-B10 is ready to be kitted out with accessories despite the unique nature of its design.

If you play CQB and need something to take on those drum-mag rocking HPA tri-shot speed-softers, the G&G ESG-B10 will give them a run for their money!

Description

If you play a lot of CQB and you really want to punish the enemy, the best tool for the job is the G&G Armament ESG-B10 Gas Shotgun. This bullpup shotgun is ultra-compact and hits out with a devasting 5 or 10 BBs per shot, making it one of the scariest foes you can encounter on a skirmish site. Boasting full metal construction and compatibility with M4/AR-15 AEG magazines, the ESG B-10 is an entirely unique design and looks absolutely slick with its M-LOK handguard and 20mm Picatinny railed carry handle.

Starting at the front, you cannot help but notice the massive shotgun-style barrel bore of the ESG B-10, making staring down the barrel of this thing a very intimidating prospect. The barrel is unthreaded but may potentially be compatible with shotgun tracer units, though we will confirm this when we've had a chance to test it out.

Surrounding the barrel we have a CNC Machined aluminium M-LOK handguard, boasting M-LOK slots at the 3 and 9 o'clock positions, ready for M-LOK accessories or 20mm Picatinny rail adapters for M-LOK. The barrel is recessed into the handguard, meaning flawless handling and tight cornering when exchanging fire at kissing distance. On each side, we are also kitted out with a QD sling socket, ready for a QD sling swivel. The 6 o'clock handguard position also boasts a 20mm Picatinny rail hidden beneath the removable lower handguard; perfect for those who prefer a vertical or angled foregrip to steer the front end of the ESG B-10 quickly between targets.

Up top, we have a FAMAS-style carry handle boasting a 20mm Picatinny rail running along its upper surface, providing plenty of room for your choice of optical sight, PEQ lasers and even RunCam action cameras to record your skirmish prowess for the world to enjoy. The carry handle is set at the perfect height for full-face mask users and even includes a light-enhancing front iron sight paired with an open anti-glare rear sight in case you don't want to add a red dot sight.

Moving rearwards, we come to the fire controls which are positioned in front of the magazine, as a "bullpup" platform should be. The fire selector sits directly above the pistol grip, offering SAFE - 5RND - 10RND fire modes with a 90-degree throw between each, meaning familiarity and an easy training transition for M4/AR-15 users. The 5 and 10-shot modes operate in semi-automatic, offering shots as quickly as you can crank them out.

The pistol grip itself is a unique G&G ergonomic design based on popular real steel ergonomic grips, offering a filled-out backstrap and a more vertical angle than conventional "A2" style grips, reducing wrist fatigue and allowing for a more natural hold position with a short-barreled platform such as this. We have not yet been able to confirm aftermarket grip compatibility, but stay tuned!

As we reach the rear of the ESG B-10, we come to the action with its massive shotgun-style mock ejection ports on each side and significantly enlarged M4/AR-15 style magazine release. Despite being a bullpup, known for its awkward reload process, the mag release is very easy to find when working in the dark, or under pressure, meaning speedy reloads are not out of the question. The surface is also textured, meaning you'll likely never slip off the mag release at a critical moment. The ejection ports are present on each side and the charging handle can be swapped, though this is an aesthetic feature and not relevant to the in-game functionality of the ESG B-10.

The stock itself is a comfortable, modern design with a serrated butt plate for optimal grip and a sloped cheekpiece for comfort. On each side, we have another QD sling socket, ready to be fitted with a QD sling swivel and used either with a two-point sling, making use of the front socket, or a single-point sling.

Being M4/AR-15 AEG magazine compatible keeps spare magazines economical, meaning G&G won't make you pay to keep the ESG B-10 in play! The gas reservoir is located inside the stock, with the fill valve on the bottom, just to the rear of the magazine well. Filling it up requires inverting the shotgun and gas can, as you would fill a GBB pistol magazine. This reservoir holds enough gas for around 100 trigger pulls (10 shots per pull) meaning potentially 10 mags worth of shooting before you need to re-gas.

Performance-wise, while the ESG B-10 is a serious contender up close, its lack of a HOP-up restricts it to approximately 10-15 meters optimal effective range. This doesn't mean you can't use it in woodland but does mean you will have to get very close to make those shots land.

In CQB, it's a different story. The ESG B-10 is practically unrivalled in its firepower up close, and handles like a dream, making it perfect for any close-quarters scenario. The shotgun-style spread provided in the 5-shot mode is perfect for dealing with fast-moving targets, letting you point the ESG B-10 in the rough direction of an enemy player and benefit from considerably improved hit probability and far faster follow-up shots than electric shotguns or pump action shotguns.

As a CQB tool for the door-kicking specialist, you couldn't ask for better than the G&G ESG B-10. This shotgun shoots as quickly as you can pull the trigger, sending an almost inescapable cluster of BBs at the enemy feeding from common and ever-available M4/AR-15 AEG magazines. With flawless build quality, game-dominating performance and swift, intuitive handling, the G&G ESG B-10 has to be one of G&G's best unique designs yet, and we look forward to getting it into a skirmish as much as we are not looking forward to being on the receiving end!

Special Instructions

These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.

FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.

Tap the tabs below to open the relevant chart for your replica.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
