FWIW, the mako dust cover and the JP low mass bolt carrier don't play well together. The lump on the inside of this dust cover is shaped for the big scallop on the milspec bolt carrier, and the JP has a very small scallop. Being plastic and all, it won't be rocket surgery to fix, but fix it I must... as it sits, the dust cover will not close.

That rifle has almost all of the V7 kit on it, except for the selector (which I have, and will be installed), and the gas block (which I didn't use because it's not adjustable, and I need to choke down the gas for the low mass BCG and superlight buffer).
