The Primary Weapons Systems MK214 Upper 14.5" 6.5 Creedmoor Pinned & Welded assembly is built for shooters who want a refined, complete upper receiver for their AR10/SR25 pattern rifle. This MK214 upper pairs a 14.5" barrel with a pinned muzzle device to achieve a 16" overall length, delivering balanced handling while maintaining the ballistic performance of the 6.5 Creedmoor cartridge. Finished in matte black, it is designed as a ready-to-install solution that integrates smoothly with compatible large-frame AR platforms.

This upper receiver is well suited for precision-focused range use, training, and hunting where the extended reach and accuracy of 6.5 Creedmoor are appreciated. The pinned muzzle device and overall configuration aim to provide a stable, predictable shooting experience without unnecessary bulk. As with other offerings from Primary Weapons Systems, the MK214 upper reflects the manufacturer’s emphasis on thoughtful engineering and consistent craftsmanship.
