1. Receiver and barrelAlthough there are many different variations of receivers, they all have the same basic pattern and thread sizes.Barrels are generally not interchangeable between models, although the barrel threads are the same pattern for all models in all eras from all manufacturers.

#1 M91/30s on late receivers without the steps at the tang will not fit in earlier stocks that are fitted to receivers with the steps at the tang.#2 Heavy barrel M24s and M91s will require the barrel channel to be opened up on stocks fitted to the standard weight barrels.#3 M27, M28, and M28/30 rifles are relatively commonly found in all three types of stocks. They will fit in M39 stocks and vice versa, but it is not common to find them this way.

4. Magazine body/triggerguardThese are generally interchangeable with two exceptions that both involve Finnish modifications.The first is the addition of a small dimple in the side of the body to help prevent rim jams when feeding.Unmodified magazine bodies would be incorrect on M28/30s and M39s, but they will fit.The second is lengthening of the trigger hole to accommodate the M27 style trigger and this type is necessary when an M27 style trigger is used, regardless of the model rifle.

5. NosecapAll nosecaps are interchangeable with the exception of the M27, M28, M28/30, and M39 types.These must be used with the corresponding type of stock except the M28 and M28/30 types which will interchange.
