Description
The Cobalt Kinetics Pro Lite in .300 AAC Blackout with a 7.50-inch barrel and 30+1 SBA3 brace is a lightweight, compact AR pistol built for shooters who want maximum maneuverability without sacrificing reliability. Chambered in .300 Blackout, it runs both supersonic and subsonic ammo — great for suppressed use or home defense. We started stocking this in late 2024, and it’s become one of our steady sellers in this category. On our scale, it weighs just 5.7 oz stripped — that’s light enough to handle fast transitions and tight spaces.
Key Highlights
- Compact 7.50-inch barrel — keeps the overall length short for easy carry and storage, while still delivering .300 Blackout ballistics.
- 30+1 round capacity — comes with a standard AR-15 magazine, so you have plenty of firepower on tap.
- SBA3 pistol brace — adjustable, stable, and legal for pistol builds. Gives you a solid cheek weld without the NFA paperwork.
- Cobalt Kinetics Pro Lite design — billet upper and lower, M-Lok handguard, and a crisp trigger. Built to last and shoot flat.
- Customer favorite — staff note says it’s one of our most-reordered items. Guys buy one, then come back for a second.

What Buyers Ask
Will this run subsonic .300 Blackout ammo?
Yes. The Pro Lite is chambered for .300 AAC Blackout and cycles both supersonic and subsonic loads reliably. If you’re running suppressed, subsonic ammo will stay quiet and cycle the action without issues.
Can I put a suppressor on this barrel length?
Absolutely. The 7.50-inch barrel is ideal for suppressor use. Just make sure your can has a compatible mount. The handguard has enough clearance for most direct-thread or QD suppressors.
Is this considered a pistol or a rifle?
This is a pistol because it has a barrel under 16 inches and comes with an SBA3 pistol brace, not a stock. No NFA tax stamp needed. You can legally own it as a pistol, but check your state and local laws.
