Not 100% sure, but some GBBR (m4 Variants) do allow for real steel accessories such as the foregrips, stocks, pistol grips, things like that. Have someone else clear that up though, not 100% certain on the brand of gun that accepts these parts though.
Well, I would think most airsoft guns allow for real steel accessories like sights and shit. All the rails are the same.
