What is the difference between these AR-15 rifles?

The original model m&p 15 rifle and the m&p 15 sport and m&p 15 ORC. Also i'm familiar with the colt m4 carbine (and m16) being in the national guard so i'm looking to get an AR that is most similar to that.

    The original model is the civilian version of your M4. It has a collapsible stock and the fixed A2 style steel front sight, and all the bells and whistles such as forward assist, ejection port dust cover, etc.

    The sport version is a minimalist version of the original. It has the collapsible stock and A2 front sight, but does not have a forward assist or an ejection port dust cover.

    The ORC stands for "optics ready compliant." It is the same rifle as the original M&P15, but instead of the gas block with the integrated A2 style steel front sight, it features a gas block with a picatinny rail on the top. On A2 style front sights, the front sight post can block part of the view through a red dot sight or similar, although this is rarely a problem. The ORC will eliminate any risk of this, and you can put a flip-up front sight (such as the Magpul MBUS) on the gas block to allow you to use iron sights when you want to.
