Includes:
- 1x Strike Industries AR Picatinny Stock Adapter
- 1x T25 Torx Tool
Compatibility:
- AR platform firearms or any firearms that accepts Mil-Spec buffer tubes and endplates
*To use this stock on an AR platform, you'll need to switch to an upper receiver that eliminates the need for a traditional buffer and buffer tube. An example is the CMMG Dissent upper, which features an integrated recoil system.
Details:
The Strike Industries AR Picatinny Stock Adapter converts a standard AR-15 lower into a platform that accepts rear-mounted 1913 Picatinny stocks and braces. Instead of being limited to traditional receiver extensions and buffer tubes, this adapter gives you access to a wide range of folding stocks and stabilizers built around the 1913 interface.
For builders working on compact rifles, PDW-style configurations, or modernized AR projects, that flexibility is the core advantage. It allows you to move into the modular ecosystem of Picatinny-mounted rear accessories without changing platforms or abandoning the AR-15 lower you already have.
Solid Construction, Secure Interface
Machined from durable aluminum, the adapter is designed to maintain proper alignment with the lower receiver while creating a rigid rear rail section. Once installed, it provides a stable mounting surface capable of handling recoil and repeated folding and unfolding of compatible stocks. It’s engineered to integrate cleanly with the lower rather than feeling like an afterthought.
Because this adapter replaces the traditional receiver extension assembly, it is intended for builds that use a compatible 1913-mounted stock or brace system. It’s a purpose-driven solution for shooters intentionally moving away from the standard buffer tube configuration.
Built for Compact and Folding Setups
For those chasing a shorter overall footprint or a folding configuration, this adapter simplifies the process. When paired with a 1913-compatible stock, it allows for a streamlined rear profile that supports compact transport and modern styling without unnecessary bulk.
If you’re building a modular AR with a focus on flexibility and contemporary design, the Strike Industries AR Picatinny Stock Adapter provides a clean path into the 1913 ecosystem while maintaining the strength and reliability expected from an AR platform.
