I changed the firing pin retaining pin once, not a big deal. The nitrided BCG the Ruger comes with is easier to clean than the BCM. I picked up a Fail Zero NIB BCG from Primary Arms for $99 shipped for my other rifle.

Nice proper staking on the gas key with that BCM.

Please excuse my ignorance, but if you swap out the BCG how do you know it is properly headspaced?

You don't, without measuring with gauges. But with an AR, the general rule is that a new BCG with a used barrel will usually be fine. The big no no is used barrel and a used BCG from a different rifle. But to make sure, you really should check with a gauge.

Actually the BCG is blued (black oxide) and not nitrided.
Nitrided BCGs are not chrome plated inside where the bolt goes. The entire BCG inside and out is a rather flat black with a little sheen to it.
The nitrided BCGs that I have are somewhat easier to clean than phosphate or bluing treated BCGs.
Thanks.
