It seems that G&G never sleep. Not happy with producing the incredibly good value Combat Machine range, they also offer them with a full metal receiver. The same brilliant performance but with a little more weight and a receiver that looks a bit like a 416 rather than just another M4. Non blowback gearbox for simple reliable performance and ease of maintenance. Full metal gun for less than £170.00! AND it's from G&G? We must love you!

Very Impressed!
Review by
Just spent a couple of days testing this baby out. My first 'proper' airsoft rifle and I'm very impressed! I carefully followed instructions from Airlift World to setup and cleaned barrel before use (it was a bit greasy). Then setting up a 20m range with a 10cm x 10cm target to check for hop up adjustment and to zero sights (nice to have full adjustment for windage and elevation, just incase one day I do need it). Honestly, I didn't need to do a thing. Ten shots tore a large hole in the bull's eye, again and again (perfect groupings). Nice solid feel with the metal body. I great sound as each shot 'snaps' out, in many ways the sound reminded me of an old .22 air rifle I had. I need to fine some negatives and I'll struggle; concerned about Scottish rain getting into the battery compartment through the holes in the hand guard. The stock has a tiny bit of wobble, but no issues. Looking forward to a full day on the field to test it to its limits.

I bought this gun around 3 months ago as my first ever Airsoft rifle. I have to say, I'm blown away with it's quality and it's performance.

Not only does it shoot INCREDIBLY straight, it sounds really, really nice when it fires too. There's a kind of 'snap' with each shot which really makes it stand out from other similar rifles in the sound department.

The FPS consistency is unbelievable too. With 20 single shots fired, each one reached 326, 327 or 328 FPS without fail. This happens every time I skirmish and I've experienced 0 drop in FPS since day one!

So not only does it shoot and sound great, it looks awesome too. The full metal body really is worth the extra £20 or so you'll pay.

I've got friends who have paid over £100 more for their first guns who are REALLY pissed at me for my higher FPS, consistency and accuracy.

All in all, 10/10, you won't be disappointed.

Bloody brilliant!

I received this rifle from AW on Thursday and took it out for a skirmish on Saturday and it never faltered.
I would suggest on watching out for the full auto as there was quite a bit of grease on my trigger so as when i stopped firing it carried on this was no problem to fix though.

I think that G&G have struck gold with their CM line up good solid reliable weapons and all the better in full metal.

Got this about a week a go to start with i wasn't very impressed but after a little cleaning of the barrel etc I must what a weapon the power is unreal I stood about 40Ft away from my unused catflap which i'd mounted to see what damage (if any) it would do, now you might think yeah a catflap it'll destroy it but they are very hard plastic and thick as well first shot from 40 Ft away went straight through, BEAUTIFUL.

As for the accuracy I have to say don't touch the hop up leave it where it is and it's spot on, i have tried it on both semi and full auto obviously more accurate in semi but still very accurate in full as well.

Down side the receiver (charging arm) is a little loose with play in it and it doesn't open the hop catch like the M16 model think it would have made the gun a lot better if it had that function as it means if you do want to play with the hop up you have to hold open the flap whilst trying to move the hop.
