Firearm having capability for field assembly and disassembly
First Claim
1. A firearm having the capability for assembly and disassembly under field conditions, comprising:
- upper and lower receivers being secured in releasable pivotal assembly by a pivot pin and being locked in assembly by a locking pin;
a barrel mount and a handguard mount being defined by said upper receiver, said handguard mount having a first handguard mounting face;
a barrel assembly being releasably secured to said barrel mount;
a generally tubular handguard member being releasably positioned about said barrel assembly and defining a second handguard mounting face and being releasably positioned with said second handguard mounting face in face-to-face engagement with said first handguard mounting face; and
a manually actuated clamp mechanism having a clamping condition releasably securing said handguard to said upper receiver and having a releasing condition permitting separation of said handguard from said upper receiver and permitting removal of said handguard from said upper receiver.

Abstract
A firearm having modular components that can be assembled under field conditions, by using simple tools. Upper and lower receivers are assembled by pins and a barrel and gas tube are secured to the upper receiver by a barrel nut. Mounting flanges of the upper receiver and a handguard are secured in reliable assembly by a manually actuated clamp mechanism having a clamping condition releasably securing the handguard to the upper receiver and having a releasing condition permitting separation of the handguard from the upper receiver. A pocketed soft protective container receives and protects the modular firearm components until firearm assembly takes place.

11. A firearm having modular sections for protective storage and for assembly and disassembly under field conditions, comprising:
-
upper and lower separable receiver sections being secured in releasable pivotal assembly by a pivot pin and being locked in assembly by a locking pin; a barrel mount and a first handguard mount flange being defined by said upper receiver section, said first handguard mount flange defining a first handguard mounting face; a barrel assembly section being releasably secured to said barrel mount by a barrel nut of said barrel assembly section; a generally tubular handguard section being releasably positioned about said barrel assembly section and defining a second handguard mount flange having a second handguard mounting face and being releasably positioned with said second handguard mounting face in face-to-face engagement with said first handguard mounting face; and a manually actuated clamp mechanism having a clamping condition releasably clamping said first handguard mount flange to said second handguard mount flange and having a releasing condition permitting separation of said first and second handguard mount flanges and permitting removal of said handguard section from said upper receiver section. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
