Collector's Corner
The Collectors Corner is your source for rare, discontinued, and hard-to-find H&K parts and accessories. Featuring non-replenishable inventory for MP5, MP5K, G3, HK91, and more, this section is curated for collectors, builders, and restoration experts.
From factory originals to legacy surplus, these parts are no longer in production and extremely limited. Once an item sells out, it's gone for good.
No restocks. No replacements. No second chances.
