Handguard assembly and STANAG mount adapter assembly
A handguard assembly for a firearm includes a stationary handguard portion, a movable handguard portion, a catch, and a latch mechanism. The catch is positioned on an interior of the handguard assembly, and the latch mechanism is position on an exterior of the handguard assembly. Both the catch and the latch mechanism maintain the movable handguard portion in a closed position. A STANAG mount adapter assembly includes a body portion, two flange portions, and an alignment mechanism. The flange portions are positioned on opposite lateral sides of the body portion and are configured to engage a STANAG mount, while the alignment adjustment mechanism is configured to adjust the lateral alignment of the body portion with reference to the STANAG mount. The STANAG mount adapter assembly can be used together with the handguard assembly to create an elongated rail platform on an SA80 rifle.
1. A handguard assembly for a firearm, comprising:
a stationary handguard portion;
a movable handguard portion that can be moved from a closed position to an opened position;
a catch positioned on an interior of the handguard assembly, the catch maintaining the movable handguard portion in the closed position; and
a latch mechanism positioned on an exterior of the handguard assembly, the latch mechanism further maintaining the movable handguard portion in the closed position, the latch mechanism comprising:
a channel formed on one of the handguard portions;
a latch attached to another of the handguard portions, the latch movable between locked and unlocked configurations, the latch comprising a detent configured to engage the channel when the latch is in the locked configuration and to disengage the channel when the latch is in the unlocked configuration;
a pivot pin that permits rotating the latch between the locked and unlocked configurations;
a spring that is biased to normally maintain the latch to the locked configuration;
the latch comprises a plurality of teeth on an opposite end from the detent; and
the spring is positioned behind the latch adjacent to the teeth.
2. The handguard assembly of claim 1 , wherein the pivot pin is relatively closer to the spring than the detent.
3. The handguard assembly of claim 1 , wherein at least one of the handguard portions comprises a rail platform configured for associating an accessory with the rifle.
4. The handguard assembly of claim 3 , wherein the rail platform comprises one of the following: a Picatinny rail and a Weaver rail.
5. The handguard assembly of claim 4 , wherein the handguard portions are sized and shaped for use with an SA80 rifle.
6. The handguard assembly of claim 1 , wherein the handguard portions are sized and shaped for use with an SA80 rifle.
7. The handguard assembly of claim 1 , wherein:
the catch is releasable upon the application of a force in a first direction; and
the latch mechanism is releasable upon the application of a force in a second direction, the second direction being generally transverse to the first direction.
