If you’re searching for a Ruger 10/22 folding stock conversion kit, a precision-style adjustable stock for 10/22, or a durable FAB Defense UAS-R 10/22 chassis/stock upgrade, this is the kind of high-impact enhancement that can make your rifle feel more tailored, more comfortable, and easier to transport.
Purpose-Built Precision Ergonomics for the Ruger 10/22 Platform
The Ruger 10/22 is one of the most popular rimfire rifles ever made—reliable, customizable, and widely used for range work, training, and small-game applications. The FAB Defense UAS-R Precision Stock Conversion Kit is designed to elevate the 10/22’s handling by delivering a more modern interface between shooter and rifle. The result is a setup that feels more “dialed in” across different body types, shooting positions, and preferences.
Instead of working around a one-size-fits-most stock, the UAS-R approach focuses on adjustability and fit, helping you build a more consistent cheek position and overall posture—key ingredients for comfort and repeatability.
Left-Side Folding Stock: Compact Storage and Easy Transport
One of the standout features of the FXUASR1022B is its left-side folding design. Folding stocks are a favorite upgrade for shooters who want a rifle that’s easier to store and transport. With the stock folded to the left, the rifle becomes more compact for:
Range bags and tighter cases
Vehicle storage
Cabinet or safe organization
General portability when moving between locations
This folding configuration is especially popular because it can help keep the overall system streamlined while still preserving the benefits of a full-size stock when unfolded.
Adjustable Cheekrest: Comfort You Can Feel, Consistency You Can Trust
A good cheek position isn’t just about comfort—it’s about repeatability. The adjustable cheekrest on the UAS-R conversion kit helps you fine-tune your head position so your sight picture can feel more natural and consistent from session to session.
Benefits of an adjustable cheekrest
Supports a more stable head position
Helps reduce strain during extended shooting sessions
Improves comfort across different shooting styles and body sizes
Makes the rifle feel “custom fit” instead of generic
For many shooters, this is one of the most noticeable upgrades you can make—especially if you’ve ever felt like you were “hunting” for the right head position on your current stock.
Fiberglass-Reinforced Polymer Construction: Strength Without Excess Weight
The UAS-R kit is built from fiberglass-reinforced polymer, a material choice known for delivering durability while keeping weight manageable. That means you get a stock system that’s designed to handle frequent use and real-world handling while maintaining a practical overall balance.
Why fiberglass-reinforced polymer matters
Strong, rigid feel for a stable stock interface
Resistant to many common bumps, scuffs, and daily wear
Lightweight compared to many metal-heavy conversions
A practical material for frequent range use and transport
Finished in matte black, the kit also offers a clean, modern look that pairs well with a wide range of Ruger 10/22 builds.
A High-Impact Upgrade for Comfort, Fit, and Modern Handling
A stock conversion kit can change how a rifle feels more than almost any other single modification. The FAB Defense UAS-R 10/22 Precision Stock Conversion Kit is ideal for shooters who want:
A more modern ergonomic interface
Better personalization through cheekrest adjustment
Compact folding convenience
A durable, lightweight material platform
Whether your goal is a more comfortable range setup or a more compact rifle configuration, the UAS-R kit is designed to deliver a noticeable improvement in how your 10/22 handles and carries.
