KNS AR/MCX Stock Adapter Without Flange – Modular Picatinny Mounting Made Easy

Transform Your Rifle with the KNS Precision AR/MCX Adapter

Unlock next-level modularity for your rifle with the KNS AR/MCX Stock Adapter Without Flange – a precision-engineered solution for shooters looking to eliminate the buffer tube and mount picatinny-style stocks directly to their firearm. Whether you're customizing a pistol-caliber carbine or modernizing a tactical build, this adapter delivers the rock-solid reliability and flexibility KNS is known for.

🔧 Key Features:

• Modular Design – Converts AR15-style threaded buffer sockets to accept Picatinny stock attachments (like SIG MPX folding stocks).

• Flange-Free Profile – Slim, streamlined design for builds requiring minimal rear clearance.

• Secure Two-Part System – Adapter plug + rail section + hex-socket bolt = ultra-stable fit.

• Versatile Compatibility – Ideal for firearms that do not require a buffer spring, such as some MCX-style builds, 9mm PCCs, or custom platforms.

⚠️ Important Compatibility Notes:

• ❌ NOT for standard AR15 rifles with traditional buffer systems.

• ✅ Perfect for platforms where the bolt carrier group does not extend beyond the receiver.

• 🔁 When using with an AR15 lower, a takedown pin that doesn’t rely on a spring or detent must be used.

Why Choose the KNS AR/MCX Adapter?

This isn’t just a workaround – it’s a design evolution. Many firearm platforms today mimic the AR15’s rear attachment system but have no mechanical need for a buffer tube. This adapter replaces unnecessary components with mission-specific modularity. From folding stocks to PDW-style braces, it’s the streamlined bridge between form and function.

Whether you're building a compact CQB rifle, suppressor-optimized setup, or lightweight PCC, this KNS stock adapter adds value without bulk.
