Slide Tube Assembly

Shockwave NOTICE: The EX Forend is compatible with the Mossberg Shockwave platform, however Adaptive Tactical does not recommend use of the EX Forend or EX Tactical Lighted Forend in conjunction with the Shockwave firearm. The dimensions of the EX Forend combined with extreme use conditions can potentially position the shooter’s hand in close proximity to the muzzle end of the firearm. This scenario could result in serious to life threatening injuries. To minimize the potential for accidental discharges and/or serious injury, Adaptive only recommends the use of the factory forend with the safety strap.  

When installed, the EX Stock will limit quick trigger assembly removal or field stripping on Mossberg® pump shotguns due to its ergonomic pistol-grip design and alignment with the receiver.
