Testing a new Garrow Firearms prototype.
Mike Garrow of Garrow Firearms Development has created a uniquely designed AR15 upper for the 17 HMR round. The 17 HMR has been a problem child for manufacturers attempting to adapt the round to the AR platform. Garrow Firearms Development seems to have solved the problem with its gas operated locking bolt design. We tested the prototype for this video.
