This is a premier, bufferless short-barreled rifle (SBR) package curated by Shepard Arms. Built on the legendary ADM (American Defense Mfg) Fully Ambidextrous Lower, we’ve paired it with a CMMG Dissent 6.5" 300 Blackout Upper to create the ultimate compact, suppressed PDW.
This build is designed for maximum suppression, zero maintenance "hot-swaps," and superior ergonomics. Whether you want the total NFA package or want us to convert it to a pistol configuration for easier transfer, we have you covered.
The Build Components
ADM Fully Ambidextrous Lower Receiver The gold standard for ergonomic lowers. Features full bolt catch/release, magazine release, and safety selector functionality from both sides of the firearm.
CMMG Dissent Bufferless Upper (6.5" 300BLK) Chambered in the versatile .300 Blackout, the Dissent's bufferless system allows for the use of a side-folding stock or brace while maintaining a remarkably compact footprint. The 6.5" barrel is optimized for subsonic performance.
Premium Suppressor & Mounting System
Dead Air Nomad Ti-XC: Ultra-lightweight titanium construction with extreme durability.
Griffin Armament Dual-Lok System: We have upgraded this setup with the Dual-Lok HUB and Dual-Lok EZ Brake.
Why Dual-Lok? Made right here in Wisconsin, we regard this as the most robust "hot swap" adapter on the market. With zero wear items and no need to "baby" the suppressor when it gets hot, it provides a bomb-proof interface that won't seize or rattle.
Furniture & Controls
Magpul UCS Stock: Provides a solid, lightweight cheek weld and adjustable length of pull.
Rise 535 Trigger: Equipped with a crisp, performance-oriented trigger for precision shot placement.
NFA & Transfer Options
Please Read Carefully: This is currently configured as a Short Barreled Rifle (SBR) with a Suppressor, meaning it is a two-stamp NFA firearm.
The Full Package: Ships as an SBR and Suppressor. This requires Form 3 transfers to your local SOT dealer.
The "Pistol" Conversion: If you wish to avoid the SBR tax stamp/wait, we can remove the Magpul UCS stock, replace it with a folding brace, and remove the suppressor from the sale. Contact us before bidding for adjusted pricing on this option.
