The HQL is only needed for purchase or transfer. You're GTG there.
Just by going off what is being said on Scott's website...it looks like as long as I can prove this was built with the pistol grip originally years back, I should be able to add the 14 inch barrel, as long as I do it in my own home and do not plan to sell it. The overall length including birds head grip will bring it to 26.5 inches which will make it legal in MD.
but I would need an HQL to possess, correct?

You are incorrect. The weapon described is NOT an AOW because the BATFE has ruled that weapons > 26" OAL are not concealable.
