An improved detonator assembly for a black powder firearm having a breech block, a receiver, and a nipple. The detonator assembly comprises a primer and a primer carrier. The primer carrier has an axial bore dimensioned to receive the primer at one end and slip over the firearm nipple at the opposite end. The primer carrier has a lip that abuts the breech block rear end. A tab laterally extends from the lip to provide a handle for installing and removing the assembly and a visual indication that the firearm is primed.

A two stage trigger assembly for a firearm employs a pivotally mounted searprop. The searprop is selectively pivotally coupled with the trigger. Upon actuation of the trigger, the searprop initially in a first stage remains fixed relative to the sear. In a second stage, the trigger catches the searprop to pivotally force the searprop to release from the sear to fire the firearm.

Action disabling device in a firearm having among its conventional components a spring-closed breech bolt, a tubular magazine, and a pivoted cartridge lifter. The disabling device is in the form of an operating arm pivoted with one end to a fixed part of the action so as to be swingable with its other end into active and inactive positions in which the same is in and out, respectively, of the closing path of the breech bolt, and is normally spring-urged into its inactive position, with this operating arm being, on overtravel of the lifter in lift direction for lack of a cartridge thereon, engaged and taken along by the lifter into its active position to stop the breech bolt on partial closure of the same. The operating arm is one of the arms of a double-arm lever the other arm of which projects to the outside of the receiver and is there accessible to an operator's finger for swinging the operating arm to its inactive position.

In a spread-spectrum receiver, a predetermined noise floor voltage, supplied together with the output of the correlation detector as a control voltage for an AGC amplifier, is subjected to a pre-signal reception adjustment or calibration, in order to compensate for drift in the noise floor or reference voltage and to correct for gain errors in the correlation detector channel thereby insuring proper operation of the detector during the sequential detection process. For this purpose, a prescribed random signal sequence, totally different from that contained in any useful transmission to be acquired, is initially applied to the correlation detector for a predetermined period of time or calibration interval. The output of the correlation detector is sampled and stored, successive samples are compared with the predetermined or fixed reference noise floor voltage, and successive adjusted noise floor reference values are produced, representative of differences between the noise level in successive correlation samples and the predetermined noise reference. These adjusted reference values are accumulated and this accumulated noise floor is fed back to the AGC amplifier as the noise floor control reference.

A firearm safety for a firearm comprises a bracket mounted at the underside of the receiver. The bracket defines a pair of recesses for receiving detent shoulders of an operator arm. The bracket is spring-biased to permit the operator arm to be manually pivoted in snap-type fashion into one of the two recesses. The operator arm engages the trigger in one pivotal position to prevent actuation of the trigger.

Method of forming a cartridge chamber in the bore of a firearm barrel, which comprises driving into the bore of the barrel from the butt end thereof a mandrel of the surface configuration of the peripheral wall and mouth of the cartridge chamber, whereby the bore metal is squeezed into close form-fit with the mandrel, and then retracting the mandrel from the barrel bore.
