Seekins Precision / Primary Arms Exclusive 10.5" .223 Wylde Complete Upper - with 9" M-LOK MCSR Rail
Manufactured by Seekins Precision
This Seekins Precision upper has been built out specifically to Primary Arms specs to bring you one heck of a value. Featuring a quadruple quality checked, salt bath nitrided barrel with 1:8 twist to ensure the greatest possible accuracy potential topped with Seekins' new Nest enclosed flash hider. The smooth-shooting mid-length gas system is fed by a melonited gas tube for easy cleaning and easily tuneable thanks to the Seekins Precision Adjustable Low Profile Gas block, easily fitting beneath their 9" MCSR free float modular handguard cut for M-LOK accessories. The standard OEM M16/full auto pattern bolt carrier group, charging handle, and receiver round out the build for a complete, ready to-roll upper half just waiting for a good pistol or SBR lower to call home.
