This German-made OEM Heckler & Koch spring is designed for H&K MP5, SP5 and SP5K pistol/rifle models chambered in 9mm, 10mm or .40 S&W. Made from steel, the extractor spring is installed with, and applies pressure to, the extractor for proper function.

This part is German HK factory manufactured and made to the tightest of specifications and tolerances and will provide a much longer service life than low-quality POF, contract, or aftermarket extractor springs.

Whether you’re maintaining your H&K rifle or building a clone platform, the 206645 offers the reliability and precision you expect from authentic OEM components.

It is recommended that all H&K parts be installed by a qualified and trained gunsmith. Stock this essential maintenance item for your MP5-platform rifles to ensure consistent extraction performance and durability.
