From the Armorer’s Bench: The RAS C39v2 & Zhukov Combo

Let’s talk about modernizing a classic platform. The AK’s fixed stock is iconic, but it’s not always practical for transport, storage, or certain shooting positions. For years, adding a quality folding mechanism meant either a permanent weld or settling for an adapter that compromised rigidity. The New Century Arms RAS C39v2 system changes that. It’s a rear trunnion assembly designed from the ground up to accept the Magpul Zhukov stock, creating a unified system that feels like it came from the factory that way. Having handled countless stock adapters, the solid lockup and clean lines of this combo stand out immediately. It’s the kind of upgrade that makes you appreciate the engineering, not just the aesthetics.

What You’re Getting: The RAS C39v2 & Zhukov Package

This isn’t just a stock slapped onto an adapter. You’re purchasing a complete rear trunnion assembly (the RAS C39v2) that replaces your rifle’s existing rear trunnion, paired with the Magpul Zhukov-S folding stock. The installation, while requiring some mechanical aptitude, is a permanent upgrade that yields a far more secure and reliable interface than any clamp-on or screw-on adapter. The Zhukov stock provides multiple length-of-pull adjustments and a solid cheek weld, while the RAS trunnion provides the hardened steel hinge and locking mechanism. Together, they transform the handling and portability of your AK.

Key Features & Build Quality

The RAS C39v2 trunnion is machined from solid steel. When you handle it, the weight and finish communicate its purpose. The hinge pin is substantial, and the locking latch engages with a definitive, positive click that doesn’t feel sloppy. This is critical for maintaining zero on optics and for overall shooter confidence. From a law enforcement or duty perspective, that reliability in the lockup is non-negotiable.

The included Magpul Zhukov-S stock is the perfect partner. Magpul’s polymer is famously durable, and the Zhukov design is proven. It folds to the left, clearing the charging handle and optics rails. The adjustment is tool-less, with solid detents for the length of pull settings. The comb height is optimized for use with standard and optics-ready side mounts. The integration is so seamless that once installed, the assembly looks and functions as a single, OEM-level component.

Pros & Cons: A Straight-Shooting Assessment

Pros:

• ✅ Factory-Level Integration: The RAS trunnion and Zhukov stock are designed for each other, eliminating wobble and play.
• ✅ Permanent, Secure Mount: Replaces the rear trunnion for a strength that far exceeds adapter plates.
• ✅ Robust Steel Construction: The hinge and latch are built from hardened steel for long-term durability.
• ✅ Modernized Ergonomics: Adjustable length of pull and improved cheek weld over traditional fixed stocks.
• ✅ Enhanced Portability: True folding capability makes storage and vehicle transport significantly easier.

Cons:

• ❌ Requires Gunsmithing: Installation is not a simple bolt-on. It requires drilling out rivets and installing new ones. This isn’t for the first-time tool user.
• ❌ Permanent Modification: You are altering your rifle’s receiver. Reverting to the original stock configuration would require another trunnion swap.
• ❌ Investment: This is a premium upgrade. If you only need occasional folding, a cheaper, less permanent adapter exists. See our AK Stocks & Adapters category for those options.

Who This Is For (And Who Should Pass)

Buy the New Century Arms Ras C39v2 W/ Magpul Zhukov Folding Stock if:

• You own a WASR, NPAP, or other AKM-pattern rifle with a standard fixed stock trunnion and want the most robust folding solution available.
• You have intermediate to advanced gunsmithing skills or access to a competent smith.
• You value a rock-solid lockup and seamless aesthetics over a quick, removable adapter.
• Portability for storage, vehicle use, or backpack use is a primary concern.

Consider an alternative if:

• You are uncomfortable permanently modifying your rifle’s receiver. Look at our clamp-on stock adapters.
• You need a folding stock for an AK variant with a different rear trunnion (like an ACE block). Compatibility is key.
• Your budget is tight and your needs are minimal. A basic fixed polymer stock may suffice.
