Provided herein are rotatable forward grips for use with paintball markers. The forward grips can be components of a paintball marker body or can be attachments to be connected to existing paintball marker bodies and barrels. The rotation of the forward grip elements permits an operator of the paintball marker to move other paintball marker components, such as a hopper, out of the line of sight from the operator to the target. In some embodiments, the rotatable forward grip includes a stopper that can hold and release the forward grip in different rotational positions. In some embodiments, the rotatable forward grip is repositionable and can be moved from, for example, the paintball marker body to the paintball marker barrel. Also provided are kits and methods that include the provided rotatable forward grips.

An apparatus includes an energy source and an expansion structure. The energy source is configured to convey an amount of energy operable to increase a pressure of a compressible gas disposed in a chamber. The expansion structure is configured to be placed in fluid communication with the chamber and to receive a flow of the compressible gas in response to the increase in pressure. The expansion structure includes an inlet having a first diameter and an outlet having a second diameter greater than the first diameter and is configured to allow the compressible gas to expand as the compressible gas flows from the inlet to the outlet such that a supersonic free jet of the compressible gas exits the outlet. In some instances, the supersonic free jet of the compressible gas can accelerate, relative to the expansion structure, a projectile disposed outside of the expansion structure.

A blaster for shooting projectiles that includes a housing that defines a housing interior, and a variable velocity barrel assembly positioned in the housing interior. The variable velocity barrel assembly includes a barrel that defines a barrel axis and a barrel interior. The barrel includes an exit opening at a distal end thereof. At least a first opening communicates the barrel interior with an exterior of the barrel. The first opening is defined through a side wall of the barrel. A slider member that includes a cylindrical portion that surrounds the barrel is movable axially along the barrel between a maximum velocity position where the cylindrical portion covers the first opening and a minimum velocity position where the slider member does not cover the first opening.

A hop-up device for an airsoft gun allows a user to adjust the tension applied to a BB during the chambering of the BB in the airsoft gun. The hop-up device has an adjustable tension adjustment sleeve configured to constrict a desired amount around the BB. The tension adjustment sleeve provides tension on the BB when the air nozzle is seating, or chambering, the BB in the bucking lips of a rubber bucking prior to firing. By adjusting the tension adjustment sleeve, the user can increase or decrease the bucking lip tension on the BB to reduce or essentially eliminate the adverse effects from manufacturing tolerances, wear, and the like. These adverse effects can cause double feeding of the BBs, jamming, inconsistent firing, slow firing, midcap syndrome (the feed spring in the magazine is too strong and forces BBs against the air nozzle with excessive force), and the like.
