Having owned the previous generation G&G Combat Machine I was excited to hear about their upgraded product line for 2016.
A lot of the sites I play at enforce a semi auto only rule, so i was looking to upgrade my old CM16 raider with something that had a more snappy trigger response, as well as seeking out a little more range and front rail space.
I decided to purchase a G&G SR-XL with its 13.5 inch metal keymod rail system, G&G ETU (electronic trigger system) and a mosfet all at a great price point. I purchased mine from Zeroone Airsoft, they were running a discount offer for 10% G&G products over £200 meaning i picked up the SR-XL for £189, making it only £60 more expensive than the previous generation CM16.
If you are in the market for a M4 / M16 variant and are looking at the original CM16 then I would definitely recommend stretch the budget to get the extra features.
Having field tested this gun a couple of times now I love the trigger response, the low profile keymod rail, which keeps the weight down and is better to hold. I also like the swivelling buttstock which makes access to the battery easier.
The dustcover opens revealing the hopup when the charging handle is pulled back. (on the old model you had to prise it open and it kept trying to spring shut when you were adjusting the hopup).
I like the new style receiver with markings and cutouts, if feels more solid and premium despite still being a polymer body
Things i have found which are not as good are on first time of using the gun it cut out after about 3 mags – it turned out to be a lose connector on the motor, once clipped in properly it has been fine since. However I also had this issue on my old CM16 so does lead to some questions around quality control of it leaving the factory.
With the Mosfet in the buffer tube sometime getting batteries to fit in the stock can be difficult / it wouldnt let me put the stock to the shortest setting with a battery in it.
The ergonomic grip feels like it has been shaped for you first three fingers holding the grip, however when you use your primary finger to activate the trigger the fit is a little off, although not too bad with gloves its just not as good as it could have been.
I would have preferred if the hopup adjustment was the newer style wheel which clicks in place to specific numbered positions rather than the fiddly older style (having said that the hopup unit isnt bad as standard and give fairly good, consistent results)
