201	Firearm receiver assembly	US13562663	2012-07-31	US09140506B2	2015-09-22	Jesus S. Gomez
An upper receiver assembly for a firearm having an upper receiver with an integral barrel nut, a handguard assembly and a barrel nut assembly with a barrel and lock nut is provided. The barrel is received by the upper receiver and is secured directly to the upper receiver using the lock nut. The upper receiver also includes an integral handguard mounting member to which the handguard assembly may be directly attached. The upper receiver assembly allows the user to attach both the barrel and handguard assemblies directly to the upper receiver, independently of one another.

213	Manufacturing process of a unitary barrel, chamber and action for a firearm	US12832170	2010-07-08	US08365647B2	2013-02-05	Karl C. Lippard
A unitary barrel, chamber and action assembly for a firearm is manufactured from a single piece of metal stock so as to precisely and consistently meet headspace requirements. A single piece of metal stock having a bore centerline is successively reamed based on a common datum to achieve precise headspace compliance. The unitary assembly is then profiled, again based on measurements from the datum, to provide a unitary barrel, chamber and action assembly without any form of juncture, headspace or harmonic limitations.

220	Paintball-gun barrel modifications that increase repeatability and accuracy	US10962156	2004-10-07	US20060075673A1	2006-04-13	John Goepfert
An improved paint gun barrel for use in conjunction with available paintball maker guns that fire thin-skinned ball with contents varying from paint to pepper compounds. This improved barrel assembly features three major improvements. The first uses of a non-floating bore bushing that is manufactured using precision and tight tolerances, which provide alignment and consistency. The second is the use of chamfers to center and align the firing path of the gun. These chamfers force said bore bushing against and center it to the breech face of the marker gun while aligning the firing path by centering the muzzle-end subassembly to said bushing. The thin-skinned ball is projected, by a force of gas, down a tightly fitted bushing. This bushing is held in suspension rigidly by the compression between the maker gun itself, and the subassembly members. This compression combined with the use of chamfers force a consistent, rigid and perfect alignment along the paintball's firing path. The third is a method of selecting the bore bushing for proper size and fit given factors of temperature, humidity and the paintballs available to the end user. The combination of these improvements increases the firing distance and accuracy while reducing the exposure to paintball ruptures within the system. Such a combination has not been achieved prior to this invention.
