I received some parts in the mail yesterday from Bravo Company USA (BCM) that I ordered for the AR upper build, and unfortunately I forgot to load the picture of them I took last night. I went ahead and picked up BCM's own bolt and carrier set so that they're matched; normally I like to keep the bolt the same brand as the barrel, but right now there's not a single Daniel Defense bolt out there. Reading about the BCM bolt and carrier, they fire one high-pressure test round with the bolt and then do Magnetic Particle Inspection to look for any cracks or flaws. This gives peace of mind that the bolt won't fail when you need it most, which is worth it in my book for the ~$30 extra you pay for it.
I also picked up a BCM Gunfighter charging handle, the medium latch one, and to say I'm impressed is an understatement. I will be buying one of these for the little-AR-from-DPMS, and every AR I own thereafter. Super piece of gear. I did a comparison by feel of a standard charging handle vs the Gunfighter, and the Gunfighter is much more solid, slick, and really does feel like you're side-charging the gun. For $44 it's a bargain. With that said, a Mil-Spec charging handle will do the job, and has been in combat, but the added grip given by the Gunfighter and mental insurance that it has more metal to it and won't break when you're yanking on it is worth it. Also, if you're running a scope on your AR, it's really helpful to be able to charge the gun from the side vice doing the two-fingers manipulation using your index and middle finger which is a pain. Go here if you want an in-depth review of the BCM Gunfighter charging handle that includes comparison pictures to a mil-spec one, and here if you want to see visual confirmation of a failed mil-spec charging handle.
Next up is an optic, and then I'll be putting rounds downrange.
