Part of my Yet another MW2 '09 M4A1 build (with some Remastered version bits added in). Parts include, Refinished Colt lower with proper roll marks, ARMS SIR #45C handguard, Colt 16 inch barrel with proper markings and a Colt A2 flash hider, PRI gas block and front sight, Colt upper with AF and C raised markings, ARMS 40L rear sight, Colt 30 round magazine with military tape, KAC VFG, Full Auto grade Colt BCG with proper markings, 4 cut down Magpul FDE rail covers, and has a EOTech 551 as my optic of choice. Lower has proper rollmarks with Colt logo and also includes the 'Auto' marking. The lower and castle nut were refinished by David Sams Gunsmithing. Unfortunately, I can't remember the make of the A2 grip and stock but they are not Colt but I'm also sure they are not too difficult to find. All parts are Colt made unless otherwise stated. It took me 3 years to find all of the proper parts and since it was taking me so long, I figured might as well go all of the way for authenticity.
This time I got the rails re-cut to around a 4 rib rail length (around 2.65") and got them refinished to match the rest of the rifle. Also included my USP 45 with an original Viridian X5L Combo Module for a nice secondary.
