General Information
This was a full metal Dboy full metal M4 (changed all of the internals including hop-up/barrel) but i added a Matrix SPR MOD-0 rails to it so it is now a MK12 with a 3x-9x illuminated scope, Dboy grip/PEQ, bi-pod, flip up front/back irons sights, suppressor, and crane stock. My rifle is inspired by Matthew Axelsons MK12- MOD-0 SPR (fallen Navy Seal from Operation Red Wings 2005)
