Elevate Your GSG MP40: The Ultimate 922r Compliance & Stock Kit for Rifle Conversion

Are you an owner of the iconic GSG MP40 .22LR pistol, captivated by its historical design and enjoyable shooting experience, but yearning for the enhanced stability and versatility of a rifle configuration? Perhaps you're navigating the complexities of U.S. firearm regulations and need a clear, reliable path to legally transform your pistol into a compliant rifle. Look no further. The GSG German Sports Guns GSGP40STKKT Stock Kit is the definitive answer, meticulously engineered to provide all the necessary components for a seamless, legal, and functional conversion.

This comprehensive kit isn't just a collection of parts; it's a precisely curated solution designed to address the specific requirements of 922r compliance, a critical aspect of federal firearms law that governs imported firearms with certain features. For enthusiasts who appreciate both historical accuracy and modern functionality, the GSGP40STKKT offers an unparalleled opportunity to optimize their GSG MP40.

Understanding the Importance of 922r Compliance for Your GSG MP40

Many firearms imported into the United States, particularly those that can be configured in a non-sporting rifle setup (like a pistol converted to a rifle with a folding stock), are subject to the regulations set forth in 18 U.S.C. § 922(r). This law, often referred to as "922r," mandates that such firearms must incorporate a minimum number of U.S.-made parts to ensure compliance. The GSG MP40 .22LR pistol, while imported, is often a prime candidate for conversion into a carbine or rifle. Without the correct U.S.-sourced components, transforming your GSG MP40 pistol into a rifle, especially one with a folding stock, could put you in non-compliance with federal law.

The GSG German Sports Guns GSGP40STKKT Stock Kit directly addresses this by supplying four crucial, 100% USA-manufactured parts. By integrating these components, owners can confidently meet the necessary U.S. parts count, ensuring their newly configured GSG MP40 rifle is fully compliant and ready for the range, collection display, or responsible recreational use. This kit takes the guesswork out of compliance, offering peace of mind alongside enhanced functionality.

Introducing the GSG German Sports Guns GSGP40STKKT Stock Kit: A Deep Dive into Its Components

The GSGP40STKKT Stock Kit is a testament to precision engineering and dedication to quality. Each component within this kit has been carefully selected and manufactured in the USA to not only meet the stringent requirements of 922r but also to enhance the overall performance and aesthetics of your GSG MP40.

Here’s a detailed look at the core elements that make this kit an indispensable upgrade:

1. The Robust 12L14 Steel Folding Stock with Folding Butt Plate

At the heart of this kit is the meticulously crafted folding stock, constructed from robust 12L14 steel. This material choice is paramount, offering exceptional strength, rigidity, and durability. Unlike lighter alloys or polymer alternatives, 12L14 steel provides the necessary resilience to withstand rigorous use, ensuring your stock remains steadfast and reliable for years to come.

• Ergonomic Enhancement: The addition of a stock transforms the handling characteristics of the GSG MP40, providing a stable third point of contact for improved accuracy, especially during sustained fire or precision shooting. This is particularly beneficial for plinking, target practice, or simply enjoying the classic feel of a carbine.
• Compact Versatility: The folding design is a significant advantage, allowing the firearm to be collapsed into a more compact form for easier transport, storage, or maneuvering in confined spaces. This feature maintains the gun's portability without sacrificing the benefits of a full stock when deployed.
• Durable Finish: The stock boasts a black parkerized finish, which is not only aesthetically pleasing, seamlessly matching the original firearm's military-inspired look, but also provides excellent corrosion resistance and a non-reflective surface. This finish ensures the stock can endure various environmental conditions while maintaining its tactical appearance.
• Authentic Feel: For those who cherish the historical lineage of the MP40, this folding stock captures the essence of the original, offering an authentic tactile experience that enhances the overall appeal of the .22LR replica.

2. Precision-Engineered 4140 Steel Muzzle Adapter

The muzzle adapter, made from high-grade 4140 steel, is another critical component for both compliance and functionality. 4140 steel is a chromium-molybdenum alloy steel known for its exceptional toughness, wear resistance, and ability to withstand high stress, making it an ideal material for a muzzle device.

• Barrel Extension/Accessory Attachment: While the GSG MP40 .22LR pistol barrel may be shorter than the legal 16-inch minimum for rifles, a muzzle adapter can contribute to meeting this length requirement when permanently affixed or allow for the attachment of other muzzle devices. This adapter is a key component in ensuring your converted rifle meets all necessary barrel length regulations, making it legally sound.
• Compliance Catalyst: As a 100% USA-manufactured part, this muzzle adapter directly contributes to the required U.S. parts count for 922r compliance, eliminating any ambiguity regarding its legal standing.
• Secure Fit: Engineered for a precise fit on the GSG MP40, the adapter integrates seamlessly with the firearm’s existing design, ensuring stability and reliable performance.

3. Critical Magazine Components: Steel Magazine Floor Plate & HDPE Polyethylene Thermoplastic Magazine Follower

The kit also includes two essential magazine components: a steel magazine floor plate and an HDPE polyethylene thermoplastic magazine follower. While seemingly minor, these parts are crucial for achieving the necessary U.S. parts count for 922r compliance.

• Steel Magazine Floor Plate: The magazine floor plate, made from durable steel, provides a robust and long-lasting base for your GSG MP40 magazines. Its U.S. origin is vital for compliance, contributing directly to the parts count.
• HDPE Polyethylene Thermoplastic Magazine Follower: The magazine follower, crafted from high-density polyethylene (HDPE) thermoplastic, offers excellent durability, low friction, and resistance to chemicals and impact. HDPE is a preferred material for magazine followers due to its ability to ensure smooth feeding of ammunition and reliable operation. This U.S.-made follower is designed for optimal performance within the GSG MP40 magazine system.
• Reliable Feeding: Beyond compliance, these components ensure the continued reliable feeding of .22LR ammunition, which is paramount for a smooth and enjoyable shooting experience. They are direct replacements for their imported counterparts, maintaining or even enhancing the magazine's functionality.
