From Ammoland:

This passage could potentially ban parts used to repair broken rifles. Banning the transfer of these rifles to anyone other than the government would mean once the rifle breaks, it is useless. If the owner repairs their gun or sells it, they are committing a felony.
Gun rights groups from around the country expressed concern about the passage of HB 961 out of the committee. One of these groups is Gun Owners of America that has been fighting hard alongside VCDL in the Commonwealth to defeat the attack on gun rights. Senior Vice President, Erich Pratt, is dismayed the bill has gotten as far as it has.
