Magazines for these are expensive, so we are thankful that in addition to the $500 discount, the Individual Officer Program also gets us a full-capacity 20-round magazine (civilian sales only include a reduced-capacity 10-round magazine), and a coupon to purchase additional 20-round magazines at a substantial discount.
I think we're going to feed it Hornady 155-grain TAP (Tactical Application Police) ammunition.
I don't care for the short rail it comes with. It's too tall to allow co-witnessing a red dot reflex sight with the OEM iron sights, for starters. Ultimak's M8 full-length rail is lower and would work, but it's fairly heavy, and very hard to find. M14.CA's full-length "Scout" rail is supposedly half the weight, just as strong, and even lower. We may give that a go. Ultimately we're looking to be able to forward scout-mount a red dot reflex sight that will co-witness with the iron sights. Then we could lose the chunky tritium XS front sight blade and replace it with a thinner National Match front sight blade.
Blackhawk makes an offset rail-mounted light mount that I think will work for us.
I'm using a 500-lumen Surefire light on the personally-owned department-authorized M4 carbine that I have carried at work for years- we may try that light out on this new rifle with a tape switch, and go from there.
Looking at a Turner National Match sling too. Probably in black, and probably the all-weather biothane version...
And possibly replace the muzzle brake with a .30-caliber A2-style flash hider.
