Senate committee substitute to the 1st edition makes the following changes.  

Amends GS 14-415.1A (possession of certain weapons by felon during commission or attempted commission of a felony) to make it unlawful for any person who is prohibited pursuant to GS 14-415.1 (general prohibition on possession of firearms by felon) from possessing a firearm or a weapon of mass death and destruction to possess a firearm or weapon of mass death and destruction during the commission or attempted commission of certain felonies (previously, prohibited any person who had been convicted of a felony from possessing such weapons during the commission of certain felonies). Changes the level of felony from Class H felony to Class G felony for a violation of the statute without any other aggravators. Specifies that a violation of the statute is a separate offense from GS 14-415.1, in addition to the underlying felony offense, and will not merge with either offense.
