That is the nicest LN CMPI've seen. You got lucky! The receiver has USMC characteristics.
The cut-off and buttplate are Rem 03A3 parts.
Kirk - I have a stock with the exact relief cut under the bolt handle. Not Army, but I believe arsenal work. I'd like to know more myself.
Hsr - The Marines shot hell out of that rifle (receiver), and so would I. At least a couple times!![]()
