B&T compression spring for ignition pin (drilled) for APC223/300

The coiled compression spring for the firing pin (striker) is an important component of the B&T APC223 and APC300. As part of the bolt assembly, it ensures the correct tension for the ignition mechanism. This original spare part from B&T is precisely manufactured to guarantee the reliability and safety of the weapon. Function: The spring keeps the firing pin under preload and ensures that it reliably returns to the starting position after the shot is fired. This prevents the striker from protruding uncontrollably and ensures a constant, safe ignition function. Compatibility: Fits exclusively for the B&T models APC223 (caliber .223 Remington / 5.56×45 mm) and APC300 (.300 AAC Blackout / 7.62×35 mm). The same spring is used in both models to ensure flawless ignition function. Assembly: Part of the bolt/striker assembly of the APC series. The spring (also called striker spring) is located in the bolt behind the firing pin and is part of the ignition mechanism. It works in conjunction with the firing pin and bolt to ensure the correct function of the striker system. Material: Made from high-quality spring steel for high fatigue strength and corrosion resistance. The coiled (multi-wire) spring construction provides uniform spring force and a long service life – even under intense stress. Replacement: In case of wear or ignition problems, the spring can be replaced one-to-one with this original spare part. Installation should be carried out according to the manufacturer's instructions. If in doubt, it is advisable to have it done by a gunsmith.
