Where would you find the full set of specs for an M-4? I wanna build an M-4 gery on a pre ban rifle I have now. I want to get it as close to current issue as I can.
Thanks

Buy a full auto Colt M4 upper and regular Colt M4 buttstock. Have the carrier turned to full circle AR15 specs by Kurt Wala. (I had him do this and he does excellent work) Use the H buffer in the stock. Pay for SBR and put a KAC flash hider on or attach a Vortex, Phantom, Gemtech Bilock, or KKF A3 flash hider to make the length 16"
You can add a KAC RAS, KAC 300m rear sight and an old Aimpoint Comp M if you want to copy the newer railed versions or add a TA01NSN instead of the old style Aimpoint.
The military M4 is less than ideal but this will get you as close as you can get to the real thing.
