Ok. Here are the details on my latest build I am calling the Burnt Bronze Lightweight Carbine. This was my first experience with applying Cerakote. I sand blasted the upper/lower receiver, hand guard and CTR stock and sprayed them with Burnt Bronze Cerakote (The heat cured version) Lower.... *Palmetto State Multi Cal. Lower *ALG ACT Trigger *Seekins Precision Mag Release Button *Norgon Ambi Catch magazine release *Magpul MOE grip *Magpul CTR Stock *Noveske QD end plate Upper.... *Started with a stripped receiver *Spikes Tactical CHF 5.56 1/7 twist chrome lined 14.5" optimum profile barrel w/ mid-length gas port *Spikes Tactical Dynacomp - Pinned *Troy Industries low profile gas block *WMD Nitromet Mid-length gas tube *10.25 Diamondhead VRS T free float hand guard *Rubber City Armory Nitride coated BCG *Fortis mfg. HAMMER charging handle *Troy Industries folding Di-Optic Aperture Tritium Battle Sight Rear *Troy Industries front folding Tritium M4 style Battle Sight *Ergo rail covers Got to test fire it today and it ran like a champ. Ran 60 rounds through 2 Troy Battle Mags without a hiccup. This rifle weighs in a 6 lbs. 10 oz. empty and 7 lbs. 10 oz. with a loaded 30 round mag. I can't believe how smooth it shoots with the mid length gas system. virtually zero muzzle climb. This is one of my favorite builds.
