Abstract: Disclosed herein is a modified upper receiver assembly and method of assembly, which in one form is operatively configured to be fitted to a conventional lower receiver of a rifle so the user can use their normal lower receiver having a pistol grip, trigger assembly and butt stock. The upper receiver is configured to provide a blowback bolt assembly of larger mass than would be possible with similar density materials of a bolt fitted within an upper receiver conventionally made for said lower receiver.
Abstract: A rifle conversion platform assembly comprised of components to fit around an existing action such that attachment locations such as a hand guard, pistol grip, and butt stock attachment locations are provided to have conventional rifle components, which in one form may be components of a high caliber semiautomatic rifle such as an AR-15, attached thereto.
