Hi there. I'm the resident newbie of the boards lurking everywhere and I have yet another stupid question to ask. Is cleaning my Bushmaster XM15-E2S going to be difficult? The only realy experience I have with disassembling and cleaning guns is cracking open my paintball gun for oiling or swabbing down the barrel of a shotgun. I'm a little leery about taking my gun apart, simply because I fear I won't be able to get it back together into working condition again. After reading the warning about the cam pin from bushmaster, I'm worried that I'll clean the gun, only to have it blow up in my face when I try to fire it again.
