In theory,you SHOULD be able to build about any relatively modern military or commercial rifle with the barrel,bolt,etc that come from the stockroom parts bins that are made to the tolerances on the blueprint.

Including a 1903 Springfield

But a riflemaker who has respect for his/her craft will check headspace on every firearm they build.

The AR mechanic will spend money on special vise jaws and barrel nut wrenches,etc,but What? $ 40 for a set of headspace gauges is too much?

Or just take your barrel assy and stripped bolt and go see your local gunsmith.

Buy some powder,brass,and bullets and ask about a quick headspace check.
