So I just bought my first M&P15 and I got the OR model. I want to put all flat dark earth Magpul accessories on it and right now my next move is the handguard. This is carbine length right? I feel like this obvious but I just need to make sure.

I got an EOtech for it as well as some flip ups. I want to get a good green laser as well, any suggestions?

I'm open to all info! thanks!
