418 (1987), this evidence sufficiently supports the finding that the rifle was subject to Gregory’s dominion and control. Thus, he knowingly and intentionally possessed the rifle. See Davis, 12 Va.App. at 733, 406 S.E.2d at 924-25 (finding sufficient evidence of knowledge, and dominion and control where marijuana found in defendant’s house and he told police they could find it in the basement). III. PROOF THAT THE ITEM WAS A FIREARM Gregory further contends that the evidence failed to prove that the Remington model 522 semi-automatic rifle was a “firearm.” While not defined by Code § 18.2-308.2, a “firearm” for purposes of this statute is any device “that propel[s] a projectile by an explosion or discharge of gunpowder.” Jones v. Commonwealth, 16 Va.App. 354, 356, 429 S.E.2d 615, 616 (<HOLDING>), aff’d en banc, 17 Va.App. 233, 436 S.E.2d 192
