I just finished building up my new custom built Dissipator upper from Del-Ton. Features a Smith Vortex FH, YHM flip-up front sight block, YHM low profile gas block, KAC M5 RAS, MAGPUL AFG, Matech BUIS, and Millett DMS-1 1-4x24 Tactical scope/ Burris P.E.P.R. scope mount. It will be mounted on a DTI lower with a MAGPUL MOE pistol grip and VLTOR E-MOD Mil-Spec stock. Should have complete pics up around Friday.
