HK MP5 SP5 Extractor Spring

Ensure reliable performance with this essential bolt head spring, specifically designed for HK SP5 and MP5 clones. Over time, this spring naturally wears and may cause ejection issues, making it a key component to monitor and replace as needed. While there is no set round count for wear, eventual replacement is necessary for optimal functionality. Crafted in Germany by Heckler & Koch, this high-quality spring helps maintain smooth operation for your firearm.
