When Brian Dick restored my Long Branch Sniper (which was missing the front pad), I had already sent him one which I had purchased from Sarco (probably the same supplier as Numrich). Brian's response was to reject it, and went back to the UK for one that was 100% MoD quality. Evidently the US supplied pads (which are probably sourced from Wayne in Taiwan, but not sure) do not have close enough tolerances.
