Martin08:

A small correction for you, in SRS NMP means a National Match rifle with a pistol grip stock (these can also be denoted NMC, for the type C stock).

A quick look in the SRS DCM book, I don't see any 1,265,1XX rifles listed as NMP, only as Sporters. If you have a desire to PM me your complete serial number, I will confirm what SRS lists it as.

There are several NMP rifles from 1,265,376 to 1,265,382 (6 rifles) those would be National Match rifles with a pistol grip stock.

While I was looking, 1,265,267, 1,265,337, 1,265,347, 1,265,369, and 1,265,430 are all listed as MOD (modified) now those should be interesting rifles!
