MPED Issue

Ever since I purchased my MPED the locking mechanism on the windage turret is INCREDIBLY stiff to the point it is mostly unusable. I cannot disengage the lock from behind the rifle and have to use two hands to unlock the turret and it often takes multiple tries.

I have contacted Bushnell and have not received a response. Has anyone experienced this or have any way to loosen to the locking mechanism? I removed the turret cap and didn’t see any obvious way to remedy this.
