GR-15 Raider Blowback Metal Body

amurph0

I've got a GR-15 Raider with blowback and i'm just wondering whether or not i can use other types of M4 receivers for it?

I want to replace the plastic body that came with it with a metal one and i'm worried that because it has a blowback feature that it won't be compatible.

This is the metal body i'm planning on getting for it:

Bump, I too would like to know if this is possible. Are there any nuances to switching out receivers? In particular the front rail, as there seems to be a knack to it's removal and I don't want to go and damage the thing by fiddling with it.

Thanks to any who can provide some advice!

RABBIT.

can the blowback feature be removed from the aeg? as in, is it a seperate part, if so i cant see why not. you just wont have it on the new upper.(i could be wrong on this so im sure someone will correct me if i am)

no, I wanted to know the same thing, eventually just accepted the fibre body, it's better than buying some crap metal body i find anyways, the blowback can be disabled but it will reduce the FPS a lot, and because if the BB feature it will not fir into normal M4 bodies, I was told to Contact G&G and ask them for a metal body, ended up leaving it though as i like it being light.

hop it helps

Disabled mine tuesday and was chronoed wednesday at .97 joule as it always was and it can be fitted into a metal body but will take alot of fileing and dremilling so probably not worth the hassle or you can just take the blowback system off all together and it will fit into any body with no dremilling/filing .

Did you replace the cylinder? With the blowback unit off of the top, it can leak a good bit from the stock cylinder, as there's nothing resisting the airflow (where once the pneumatic blowback was) - if you want the blowback disabled, you can replace the cylinder and be sorted without any loss, potential or otherwise, in FPS.

If you remove the aluminium sheet, which disables the blowback feature while retaining the pneumatic element there will be no dip in FPS, but removing the whole unit should drop the fps due to air now being bled from the cylinder.

hmm strange, good in a way, the fibre body doesn't really bother me all that much anyways as it kind of balances the weight of the grenade launcher but still nice to know.

THE MINDER

To clarify what Inari said when you remove the blowback cylinder you are left with a small hole on the top of original cylinder(Thats what works the blowback) You will have at the very least major difficulty getting it to fit and work properly in a standard metal body(If you can get it to fit at all that is)
