JD machine G3 308 Upper

[cqr777]

Hello , does anyone know if this upper will work with a normal dpms 308 lower , one that doesn't take the G3 mags? if so i will buy one this second , i would really like to know since it looks so damn good with no forward assist !

Yes, it does work, but you wouldn't be able to use the bolt catch with the G3 upper.
