PRO2A LEFT HAND 5" 300 Blackout 1/5 Micro Length Melonite M-LOK AR-15 Upper - Suppressor Ready

Product Description

Shrink your footprint to the absolute minimum without traditional ergonomic drawbacks or stabilization failure. The PRO2A LEFT HAND 5" 300 Blackout Micro Length Upper delivers premium Personal Defense Weapon (PDW) engineering in an ultra-short profile built natively for southpaw operators. Utilizing a mirrored left-ejecting receiver profile and a matching left-hand M16 bolt carrier group, this assembly routes gas pressure and spent casings safely down the left side, entirely removing the facial blowback that lefties traditionally face when running short-barrel setups. The 5-inch 4150 CMV barrel utilizes an ultra-fast 1:5 twist rate to maximize rotational stabilization for heavy subsonic projectile trajectories. An abbreviated 4-inch free-float slim profile handguard exposes the muzzle threads completely, ensuring clean structural real estate to directly mount quick-attach or direct-thread suppressors without any rail-to-silencer interference.

Key Features

• True Left-Hand Architecture: Dedicated left-side ejection layout eliminates facial gas blowback and crossing casing paths for left-handed operators.
• Ultra-Fast 1:5 Twist Rate: Precision-engineered rotational torque stabilizes standard and heavy-grain 300 Blackout projectiles cleanly out of a micro-length barrel profile.
• Suppressor-Ready Clearance: A compact 4-inch M-LOK handguard leaves muzzle threads entirely exposed, allowing seamless mounting and removal of suppressors and muzzle accessories without rail interference.
• Micro-Length Gas Management: Fine-tuned micro direct impingement gas system provides predictable dwell times and smooth cycling pressure curves.
• Premium QPQ Melonite Protection: Liquid bath nitride treated 4150 Chrome Moly Vanadium steel core delivers supreme friction defense, deep weather proofing, and long throat life.

Why Choose This Product?

The 300 Blackout cartridge is inherently optimized for shorter barrel configurations, turning an ultra-compact footprint into a hard-hitting defensive tool. By combining this micro performance with a fast 1:5 twist profile and a short 4-inch M-LOK handguard that avoids rail-suppressor interference, Pro2A Tactical yields an uncompromised custom weapon package that drops seamlessly onto your existing left-handed AR-15 lower receiver.
