Built by Ralph at RDTS using an Fleming HK registered sear in all three calibers. This awesome machine gun interchanges from a 9" brl to 17.25 brl with just a locking piece change (9" barrel as pictured is installed). This rare beauty sends .308 rounds down range a jaw dropping 850 rounds per minute. Amazing firepower in such a small reliable package. Very few of this model and configuration are in existence. Sorry ammo and scope not included. All NFA rules apply.
