ONLY ONE AVAILABLE AT THE STORE, ELITE AUTHENTIC FACTORY HK 3 POSTION STOCK.

IF YOU HAVE AN HK FIREARM, YOU HAVE ALREADY PAID TO HAVE HK LEGENDARY QUALITY, DON'T CHEAP OUT FOR AN AFTERMARKET STOCK TO SAVE A LITTLE MONEY NOW.

Up for auction is the ultimate upgrade for your roller-delayed icon: an authentic, original German-manufactured Heckler & Koch 3-Position Retractable Buttstock. This premium stock carries factory MPN 227901 and is completely brand-new-in-bag. It remains in its original, heavy-duty factory ziplock packaging exactly as it was imported from Germany, complete with the official manufacturer barcode label intact. The bag has been opened for inspection and photography, and the stock itself has never been mounted, handled, or altered, ensuring it arrives at your door in flawless, pristine factory condition. For collectors, purists, and clone builders looking to build the ultimate short-barreled rifle or complete an authentic HK setup, original factory parts represent the highest possible tier of quality, retaining value far better than any commercial aftermarket alternative.

This specific factory accessory is experiencing an unprecedented surge in market demand due to historic, sweeping changes in federal law interpretations regarding the National Firearms Act NFA, triggering a massive wave of enthusiasts legally upgrading their full-sized SP5 and MP5 pistols with comfortable, authentic shoulder stocks. Because these highly desirable German-made stocks can now be legally enjoyed they have become incredibly harder to source.

This retractable stock is manufactured to the exact engineering tolerances and heavy-duty material specifications required for modern hard-use environments. It is constructed with a robust steel and polymer frame that effortlessly transitions between three distinct locking positions, providing an exceptional balance of compact storage and stable, repeatable performance when extended. It comes equipped with an updated factory buffer mechanism and a high-traction rubber buttpad designed to significantly mitigate felt recoil. This stock is explicitly engineered as a perfect drop-in fit for the full-size HK SP5, original MP5 variants, and HK94 platforms chambered in 9mm, 10mm, and .40 S&W.

Because authentic German HK inventory is released in highly limited import waves, these stocks are famously prone to immediate sell-outs at major distributors. Do not miss this rare opportunity to bypass the retail waiting lists and secure a completely untouched piece of premium German engineering during this historic era of firearm customization. While federal registration rules are unchanged, ALL NFA RULES APPLY and do not supersede restrictive state or local laws, so please ensure you remain in full compliance with your specific regional regulations before purchasing.
