I could very well believe that about the mount. We were not allowed to change the mounts or anything else about our issued rifles other than the sling. I will reconsider the small H1 and T1 with quality mounts.It is more about the factory Aimpoint mount. Had same problems on issues optics so last deployment I switched to Larue mount and it fixed it right up. The T-1 and H-1 are pretty much money. You can go with a Bushnell TRS-25 or a Primary Arms T-1 clone for $70-90 and resell if you decide to drop the cash on the real deal.
