I heard the 11.5 are better both on reliability and ballistics.

I agree with that, but I doubt you will have a reliability issue with an LMT or Noveske 10.5'. I actually run a Denny's Guns/GTS 12.5" Operator barrel on my M16. It has run flawlesly on my rifle and the extra length has even better ballistics.

You also own a rabbit, so your advice is taken with a grain of salt.

Don't knock the rabbit. The rabbit is cool.

If it dies, that means your ole lady is preggers. BTW I ordered the basic 10.5" LMT upper and a BCM Auto BCG. Woot woot?
