AR10 and AR15 mags

[lone_viper]

Hi all,

 

Just acquired a new rif, but realised that the lower receiver is actually built around an AR10 platform and not AR15/M4 therefore the mags are obviously different......  

Does anyone know of a Magwell insert you can get to convert an AR10 magwell to accept AR15/M4 mags??   I can find only 1 around, but that is for a specific make of rifle, and I am not sure if it will be compatible?

 

Or if anyone has a 3D model for one, and by luck I have a 3D printer on order, but its going to take some time to get up to speed if I have to build it from scratch........
