Frequently Asked Questions

What are common issues with the Desert Tech MDR in 6.5 Creedmoor?

A primary issue noted is magazine compatibility, specifically with 25-round PMAGs, which can cause feeding problems due to cartridge geometry. Malfunctions can also occur if the gas block setting is too low, particularly during off-hand shooting stages.

How does the 6.5 Creedmoor MDR compare in recoil to the .308 Winchester version?

According to the reviewer, the 6.5 Creedmoor variant of the Desert Tech MDR recoils much more smoothly and controllably than the .308 Winchester version, making it a more pleasant shooting experience.

Can the Primary Arms 1-8x ACSS optic be used effectively with the 6.5 Creedmoor?

Yes, the ACSS reticle's BDC designed for 5.56/.308 can work for 6.5 Creedmoor if you adjust your holdover slightly higher. However, the optic's tight eye box may be a limitation for high-speed competition.

What is the recommended magazine capacity for the Desert Tech MDR in 6.5 Creedmoor?
