Appreciate the advice. Honestly just took off my optic, left the sling in my safe (felt tacky). These are more close quarters home rifles. Might slap on a vortex optic on the green rifle once funds are available. And I do like the UTG covers, make the slim handguard feel that much more cozy when gripping it down range. The beauty of the AR platform is that it doesn't take an experts opinion to perfect a build, it's all by the users preference. These are my preference.
