PRO2A LEFT HAND 8.5" 300 Blackout 1/7 Pistol Length Melonite M-LOK AR-15 Upper Kit

Product Description

Achieve an ideal configuration of short-barrel mobility and maximized intermediate velocity with the PRO2A LEFT HAND 8.5" 300 Blackout Upper Kit. Purpose-built from the ground up natively for left-handed operators, this complete package completely eliminates cross-body brass throwing and facial gas blowback via its mirrored left-ejecting receiver system. The 8.5-inch medium profile barrel delivers optimized powder burn efficiency for the versatile 300 Blackout cartridge, utilizing a 1:7 twist rate to flawlessly stabilize heavy subsonic match projectiles as well as supersonic defense and hunting loads. Paired with a slim 7-inch free-float M-LOK handguard and an all-inclusive lower conversion package, this turnkey kit streamlines your entire custom southpaw build project.
