Abstract
The present embodiments disclose a handguard for a roller-delayed firearm. The handguard includes a rail extending between a first end and a second end defining a length of a handguard and a tubular portion extending at least partially along the length of the roller delayed firearm. The tubular portion is configured to releasably engage with a male mating portion of a roller-delayed firearm. A clamp selectively secures the female mating portion of the tubular portion to the male mating portion of the receiver.
Description
- The embodiments relate to firearms, and more specifically to firearms having a modular handguard.
- Firearms often include handguards attached to the front of the firearm to aid in the grip of the weapon. The handguard protects the user from contacting the barrel, which may become hot during periods of repeated firing. The handguard may also function as an attachment point for various accessories such as optics, sights, supports, light sources, and auxiliary weapons.
- The Heckler & Koch (HK) roller-delayed firearms platforms are operated with a roller-delayed bolt. These include the HK MP5, MP5SD, 33, 33k, 51, 51k, 53, 53k, 93, 93k, 91, 91k, G3, G3k and numerous variants. These firearms platforms are used worldwide by numerous militaries, law enforcement, intelligence, and security organizations as well as firearm enthusiasts. The design includes a permanently-fixed cocking tube, which prohibits modification of the sights, rail, barrel, and the handguard itself. On the contrary, rifles such as the AR-15 and AR-10 often include releasably engaged handguards; however, these handguards are unable to be used with the HK roller delayed firearms due to the configurational differences between the firearms. Namely, the HK roller delayed firearms include a cocking tube and charging handle components located above the handguard, requiring these components to fit within the upper portion of the handguard.
- In operation, the HK roller-delayed firearms include a bolt rigidly engaged with the barrel trunnion. The barrel trunnion is a cylindrical component welded to the receiver in which the barrel is pinned. The two-part bolt consists of a bolt head with rollers and a bolt carrier. The heavier bolt carrier lies up against the bolt head when the weapon is ready to fire. Inclined planes on the front locking piece lie between the rollers and force them out into recesses in the barrel trunnion.
- Aftermarket handguards currently available utilize bolts to affix the handguard to the firearm via the permanently fixed cocking tube. This requires a significant amount of time and proper tools for replacement which is unrealistic in variable combat and tactical settings.
- This summary is provided to introduce a variety of concepts in a simplified form that is further disclosed in the detailed description. This summary is not intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter.
- The present embodiments disclose a handguard for a roller-delayed firearm. The handguard includes a rail extending between a first end and a second end defining a length of a handguard and a tubular portion extending at least partially along the length of the roller-delayed firearm. The tubular portion includes a female mating portion configured to releasably engage with a male mating portion on the receiver of a roller-delayed firearm. A clamp selectively secures the tubular portion to the male mating portion of the receiver.
- In one aspect, the tubular portion is dimensioned to at least partially cover a barrel of the roller-delayed firearm. Alternatively, the tubular portion is dimensioned to at least partially cover a muzzle device of the roller-delayed firearm.
- In one aspect, the clamp affects a first element and a second element to releasably engage the handguard to the receiver. The clamp may include a quick-disconnect mechanism comprised of a lever to adjust a first element and a second element to impart friction.
- In one aspect, the upper handguard portion includes a slide to accommodate the cocking lever of the roller-delayed firearm.
- In one aspect, the handguard allows for a user to interchange the otherwise fused components of an HK roller-delayed firearm allowing for the replacement of the barrel and sights of the firearm. Fused components can include the sights, the barrel, the receiver, and the rail in addition to the internal charging components of the HK roller-delayed firearm. The interchangeability allows for the HK roller-delayed firearm to be used in a broader array of scenarios wherein the firearm would normally limit the ability of the user to utilize existing or future components or accessories.
- In one aspect, the continuously extends along a substantial length of the firearm to maximize the capacity for accessories to be mounted thereon.

FIG. 5 illustrates an exemplary embodiment of thereceiver 190. Amale mating portion 510 allows for the releasable engagement of the handguard. Themale mating portion 510 has a perimeter dimensioned to be held in position by the female mating portion 207 (seeFIG. 2 ) and the frictional force of thehandguard clamp 230 or the quick-disconnect mechanism thereof. - In some embodiments, the male mating portion is configured as a circumferential ring having a complementary shape with respect to the tubular portion of the handguard.
- In some embodiments, the
handguard 150 replaces the need to weld or otherwise fuse the cocking tube and support, front post sight, triple frame, barrel hanger, and internal cocking tube components to the handguard in modern roller-delayed firearms. In such embodiments, thehandguard 150 allows for the replacement of the otherwise welded or fused components for various utilities and scenarios. - In some embodiments, the rail is continuous along a substantial length of the firearm. Preferentially, the rail extends from the
forward end 205 of the handguard and terminates above thegrip frame 110 to maximize the capacity for mounting accessories thereto. - In some embodiments, the
handguard 150 is constructed of metal or a sufficiently rigid polymer to ensure the structural integrity of the firearm during repeated use. Similarly, therail 155 is constructed of a metal or a sufficiently rigid polymer. Therail 155 can be provided as a dovetail rail, a weaver rail, a Warsaw rail, a Picatinny rail, Keymod rail, and an M-LOK rail. - In some embodiments, the
