M4 metal body compatibility

[Patdod]

I have a G&G GR-16 (M16 lenght) with a lower tinted receiver that I think is made with reinforced nylon.

I was wondering where I could find a suitable metal lower receiver that would fit with my rifle.

I was told by some persons that G&G were a bit capricious about compatibility, but that D-Boys ones should fit, can somebody confirm me this?

Oh and I would like opinion about the advantages of changing it vs keeping it as long as its operational.

I am not a big fan of changing things that are not broken, but if it's going to give me more performance why not.

Thanks for your answers and time

Speaking from personal experience, it will break.
Mine has been very well treated, but there are some serious failure points on those plastic bodies; namely where the stock meets the pseudo-buffer tube.
My gun works great. I've been able to play indoors and outdoors without issue or modification. I really like it, but after careful inspection, I can't see how that particular part wouldn't fail.
My RK47 has a very similar problem.

There are a few metal bodies floating around the classifieds but everyone I talk to seems to have a different opinion on which brands work and which don't, and few of the people I've talked to have even spent much time working on G&Gs.

I am ultimately happy with my purchase, but I think it would be real nice if the Canadian retailers who have been stocking cansoft G&G products could put some effort into bringing in G&G metal lower receivers.
There's really just no way around needing one.

From my experiences, I've had problems when trying to fit different upper and lower brands, and going with a full upper and lower kit was much easier, but had to do some minor modifications to fit front ends.

You WILL have fitment issue if the lower is not G&G and ESPECIALLY if it is a dboys. Just finished putting a scratch m4 together with a dboys body. Got it done but what a nightmare. The clear lowers are not nylon btw they are a cheap as shit tinted plastic. The tint makes it less strong by polluting the plastic. Leave it till it breaks and then buy a complete metal body, you will have less issues this way.

Yhea, G&G clear bodies are kind of shitty. They are full of air bubbles...

[Patdod]

But would any full metal body (upper and lower) fit with the rest of my G&G GR-16.

Thats my main concern, I don't care getting a full set but I would be so pissed if I can't fit my front and full stock with it.

Oh and the mechbox in it is V2, does that make a difference in the choice of metal body?

Every M4/M16 has a V2 mechbox.

Get a whole new metal body. Use your other one for a loaner gun in progress.

Thank you all for your answers, I really appreciated it.

Just buy a full metal king arms M4. And then build whatever you want, by combining it with your G&G. Once you are done, sell the remainers as a franken gun lol
You will save more money that way,rather than buying the body alone.

A Dboys lower will fit. My first AR was a G&G cansoft GR-16, I replaced it after parts snapped.
