0241Tactical have sent over details of their RCO-ACOG optic covers:
0241Tactical RCO-ACOG covers keep dust and debris out of your optics (which will prevent scratches) while in garrison or within the FOB. The cover fits snug over your optic and can be installed or removed in seconds (two seconds to be exact). Your weapon and optics must be able to perform in the most adverse conditions; your optic is just as significant. Keeping it free of scratched is vital. When your optics are exposed to the environments, (dust, wind, sand, etc) scratches can occur and will inhibit the full use of your weapon matching the proficiency that training and experience have given you. 0241Tactical RCO Covers will help protect your preventing scratches while garrison or when the immediate need of your optic is unlikely. Available in a wide variety of camouflage patterns (Multicam, ERDL, A-TACS, All Terrain TIger, CADPAT, AORII/III, MARPAT). Check them out at ww.0241Tactical.com
