  • Fortis Shift

    Posted by Kev Bacon on 11th Feb 2021

    This grip is excellent! Feels great in the hand, has greatly improved controllability and is extremely light at the same time. Before buying I was concerned about the hollow or open design but the Fortis Shift is very sturdy and doesn't feel weak or low quality at all.

  • Fortis, accept no other

    This is my third Fortis Vertical grip, but the first one for a KeyMod rail system. Like the 2 before it, attachment was simple and the comfort, construction and ease of use are top notch. The price was equally favorable considering the quality of craftsmanship. The newly built Colt M4 LE6920 is not weighed down by this attachment.
