Identical parts are not identical

When crafting stuff that needs two of the same part, for example the dauntelss shotgun that needs two Marksman Barel if those barrels are not created with the exact same mats they will not count as a Marksman Barel in the Dauntless Shotgun creation menu even though they have the same name.

Either the name should more exactly reflect the materials included int the production or the they should be accepted in the final productT

The attached pic shows to barrels that differ in the the mats used in the ornament

Bi=ot barells are named the same but are not usable to constuct the shotgun
