Answered by Ultradyne USA, Manufacturer from MO, United States, on January 19, 2026

Hello Todd. The Apollo S 7.62/.308 is not compatible with 6.5 PRC due to the higher pressures of the 6.5 PRC. You will need the Apollo LR 6.5: https://www.opticsplanet.com/ultradyne-ud11180-6-5-apollo-lr-compensator-5-8x24.html?_iv_caliber-193146313=6-dot-5mm-creedmoor
