Warrenton man pleads guilty to unregistered firearm

It all stems from this Incident

On Oct. 22, 2016, law enforcement was again called to Shaver’s home for a report of a domestic disturbance. During a subsequent search, law enforcement recovered a semi-automatic rifle hidden in an air vent. The semi-automatic rifle was originally sold to Shaver as a pistol through a licensed federal firearms dealer. Shaver later modified the pistol into a short-barreled rifle.

Shaver faces a maximum penalty of 10 years in prison when sentenced on June 9. The maximum statutory sentence is prescribed by Congress and is provided here for informational purposes, as the sentencing of the defendant will be determined by the court based on the advisory Sentencing Guidelines and other statutory factors.

It might help to put "unregistered NFA firearm" in the title.
