The Best Your Gonna Get. Period.
I've been using Cobratac Melonite BCG's and one of the Diamond Coated BCG's for a while now in say, 7-8 builds. All of my builds are 500 round reliability tested with steel cased 62gr crap ammo and all have passed my rigorous mag dumps/double & triple tap drills/various other move & shoot drills. These BCG's are the REAL DEAL FOR THE RIGHT PRICE! I always try to buy in bulk. Good luck, God Bless. De Oppresso Liber!
