Compact 300 Blackout Power — Optimized for Suppressed & Close-Range Use
The included PSA JAKL 8.5” 300BLK upper is engineered around a monolithic 6061 receiver with a long-stroke piston operating system, delivering exceptional reliability with both subsonic and supersonic loads. The 300 Blackout cartridge shines in short-barrel applications, making this package ideal for CQB, home defense, or suppressed shooting setups.
F5 Mfg Side Folding Adapter – Bufferless Compatibility Built In
Because the JAKL operates on a fully captured internal recoil assembly, the system does not require a traditional buffer tube. This makes the F5 Mfg folding adapter a perfect match, providing:
- A secure, stable fold with tight lock-up
- Significant reduction in overall length for transport
- Compatibility with brace interfaces like the Strike Industries Stabilizer
- A durable, American-made aluminum design engineered for hard use
Strike Industries Stabilizer – Lightweight, Comfortable, Reliable
The included Strike Industries Stabilizer enhances handling while keeping weight minimal. Engineered for modern pistol-caliber and rifle-caliber platforms, the stabilizer offers:
- Lightweight, low-profile construction
- Improved lateral control during rapid fire
- Enhanced ergonomics without unnecessary bulk
- Seamless fitment with the F5 folding adapter
