Abstract: A retractable carrying device that effectively positions an object snugly against a user's body allowing the user to carry the object from their shoulder for long periods of time without stress and irritation. The retractable carrying device maintains tension on receiving means thereby preventing undesirable noise, and also automatically and tensionally adjusts when the retractable carrying device is utilized as a stabilizing aid. The retractable carrying device is constructed with a first elongated flexible securing means, a second elongated flexible securing means, and a retractable mechanism, the retractable mechanism being enveloped by shielding means. The retractable mechanism has elastic properties and is of the type that can be stretched or extended when an opposing directional force is applied to the retractable mechanism, thereby increasing the effective length of the retractable mechanism, and which will then return or retract to its original length when the opposing directional force is released.

Abstract: A telescope inner tube locking device and method for positively locking the telescope inner tube in it's previously aligned position. The locking is accomplished by using a biased locking screw which operates to apply a force against the inner tube of the telescope while the windage and elevation adjustment screws on the telescope are moved. Thereafter, the biased locking screw locks the inner tube against the windage and elevation adjustment screws. In a modification of the preferred embodiment, the inner tube of the telescope may also be locked by using a locking screw constructed similarly to the elevation or windage screws in combination with a separate spring bias. The separate spring bias will apply a force against the windage and elevation screws of the telescope and the locking screw will lock the inner tube in place. The tube may also be locked by a third locking screw without using a bias.

Abstract: The present invention relates to improvements in a power rifle scope of the type having a tubular housing barrel with enlarged end portions and an optical axis defined by an optical system including an objective lens disposed in the enlarged front end thereof, an eyepiece lens system disposed in the enlarged other end thereof and an erector lens system intermediate the said two ends and where the improvement comprises the addition of a variable optical aperture mounted in and carried by a cylindrical guide tube which is secured interiorly of the scope barrel, a helically rotatable setting ring carried by and disposed exteriorly of the barrel and having an inwardly radially directed actuating pin which passes through the barrel and through a circumferential slot in the guide tube and operatively engages the variable aperture device to vary the light passing capacity of the barrel in response to rotation of the setting ring and sealing rings disposed between the setting ring and the barrel, for and aft of the a
