In a previous thread, a poster expressed his reluctance to add a red dot sight to his carbine because removing the receiver cover is a pain. I responded that I thought that comment was odd, since you need to remove the receiver cover in order to clean it. I was then informed by other posters that this was unnecessary, as the carbine only needs to have a bore snake pulled through it every once and a while, as recommended by the manufacturer. I can't find my manual here to see exactly what the recommended cleaning procedure is, so I was wondering if anyone here has any documentation/how-to pics, etc. I come from a Marine Corps background, so weapons maintenance is important to me. I just can't imagine that a breakdown of the receiver is unnecessary for proper maintenance. Any thoughts would be appreciated.
