Costa Ludas “Great for CQB, Firearms Training and Combative’s!”

The Costa Ludus YouTube channel published a great video demo and review of BarrelBlok and RifleBlok. We respect his knowledge and experience but do feel we should point out he put the MagBlok in the handgun magazine upside down. Having the MagBlok in the gun upside down prevents it from accomplishing its designed purpose of allowing the slide to cycle without slide lock. All around a great video that points out so many positive benefits.
