Thunderbolt Customs S1: Every military trainer and shooting expert worldwide stress that great shots start with a solid foundation. That is exactly what Sidekick Gun Rests do. They provide a solid foundation when needed and where needed. Sidekick Gun Rest systems are an advancement in shooting technology. Now you can add a highly-mobile and effective gun rest to shotguns, hunting rifles and tactical weapons. Sidekick Gun Rests stay "on-board" and ready when it is needed. To deploy, just flip the steel-claw open and lean the claw's point into a post, tree or building corner. When not needed, the claw folds out of the way. Now move rapidly from spot to spot without having to carry a carry clumsy shooting stick or bi pods to stabilize your shot. Sidekicks install below the forearm or to a stud mount. Now you have a highly-portable and integrated stabilizer the moment you need it. The Sidekick's steel claw deploys in 1/10th of second and can be installed to open on either side of the barrel. Model S1 fits most sporting guns and rifles equipped with a sling stud.
