¶1OPINION
¶2By the Court,
¶3On May 24, 1988, appellant was convicted, pursuant to a guilty plea, of two counts of robbery with use of a deadly weapon. Appellant was sentenced to two concurrent terms of fifteen years in the Nevada State Prison for each robbery conviction, plus consecutive terms of fifteen years for each use of a deadly weapon.
¶4On March 28, 1989, appellant filed in the district court a proper person petition for post-conviction relief. On April 13, 1989, the district court issued an order dismissing appellant’s petition. Appellant appealed to this court. On November 22, 1989, we issued an order of remand vacating the district court’s order.
¶5On March 16, 1990, appellant filed in the district court a second petition for post-conviction relief. Following an eviden-tiary hearing, on May 9, 1990, the district court issued its findings of fact, conclusions of law, and order denying post-conviction relief. This appeal followed.
¶6Appellant contends that the toy BB gun he used in commission of the crimes had no deadly capabilities, nor could it have been used in any manner to inflict death or great bodily harm. Therefore, appellant contends his enhanced sentences cannot stand because the BB gun was not a “deadly weapon.” We disagree.
¶7*339Pursuant to NRS 193.165(1), “[a]ny person who uses a firearm or other deadly weapon ... in the commission of a crime shall be punished by imprisonment in the state prison for a term equal to and in addition to the term of imprisonment prescribed by statute for such crime.” NRS 202.253 defines “firearm” as “any weapon with a caliber of. 177 inches or greater from which a projectile may be propelled by means of explosive, spring, gas, air or other force.” In this case, defense counsel stipulated that the caliber of the BB gun was .177 inches. A BB gun propels projectiles by means of force. The statutory language is unambiguous and the BB gun used by appellant fits squarely within the definition of “firearm.” Firearms are afforded per se deadly status. See Bias v. State, 105 Nev. 869, 784 P.2d 963 (1989); McIntyre v. State, 104 Nev. 622, 764 P.2d 482 (1988). It was therefore unnecessary for the state to establish whether the BB gun used by appellant had deadly capabilities. Accordingly, appellant’s sentences were properly enhanced pursuant to NRS 193.165(1). We therefore affirm the order of the district court denying appellant’s second petition for post-conviction relief.
¶8Although the notice of appeal states that the appeal is from the judgment of conviction, it is apparent that the appeal is taken from the district court’s order of May 9, 1990, denying appellant’s second petition for post-conviction relief. Therefore, we have treated this as a timely appeal from the order denying appellant’s second petition for post-conviction relief.
