BarrelBlok Pro Chamber and Magazine Inserts - Safe training with your own firearm

In the BarrelBlok Pro series, there are three (3) MagBlok inserts that snap into the top of an empty magazine. This device tricks the firearm into thinking it has ammunition in the magazine, preventing the slide from locking to the rear. With MagBlok inserted into an empty magazine, you know have FULL and UNRESTRICTED mechanical functionality with NO slide lock! With MagBlok inserted, you can now safely duplicate every function and malfunction in a training environment. The three MagBlok™ inserts allow the user to train with up to three magazines to simulate emergency reloads repetitiously. NOTE- MagBlok is NOT for sale separately. 

Best of all, neither your firearm or magazine have to be disassembled to use BarrelBlok or MagBlok!  Simply insert it to train and remove it to return your firearm to its full ready state. Products are made from a composite material that will not mark, damage or mar any surface of your firearm. It is durable and designed to handle the rigors of firearms training. BarrelBlok is impervious to gun oil, lubricants, and GSR. BarrelBlok and BarrelBlok Pro models are universal for each caliber and will fit into multiple firearms. BarrelBlok and BarrelBlok Pro are available in 9mm (9x19), .40 S&W, .45 ACP and .357 Sig. A .380 model will be released in late-summer 2016.
