The GOAT-15 ATOM tackles the training gap between beginner shooters and full-size rifles. Its scaled-down geometry fits smaller-framed shooters while maintaining familiar AR-15 controls and manual of arms. Perfect for introducing new shooters to semi-automatic platforms without the intimidation factor of larger calibers. The updated 1913 rail mount replaces the previous buffer tube system, giving you the flexibility to mount any compatible brace or stock of your choice.
