This is for my SHTF Bravo Company middy in 5.56. I'm torn. The 552 has the buttons in the rear, is 100% co-witnessed, and uses readily available AA batteries.
The 556 has the buttons on the side to clear a magnifier, is more compact and has a 7mm riser to give 1/3 co-witness, and uses smaller CR123 batteries. The rifle already has a CR123 powered weapon light and my Vltor EMOD stock can carry 8 CR123 batteries or 3 AA and 4 CR123 batteries in the sealed compartments. I'm wanting to save the non-sealed compartment for oil and such.
I already keep 200 or so alkaline AAs plus a 1/2 dozen lithium AAs, and 50-100 or so lithium CR123s on hand for emergencies.
I'm really torn. 1/3 co-witness vs 100%? The 556 would require the use of their new (as of May) G23 magnifier with 7mm riser instead of an Aimpoint magnifier. I'd actually save money with the 7mm riser because I wouldn't have to replace the front sight with a flip down. Then again that 7mm is 7mm more bulk.
