The defendant first assigns as error the failure of the trial court to exclude the in-court identification of the defendant by the witness Blalock. This assignment is without merit.
*175Upon timely objection by the defendant, the trial court conducted a voir dire to determine the admissibility of the witness’ identification of the defendant. Based upon competent evidence, the trial court found the witness had ample opportunity to observe the defendant at close range in well-lighted circumstances with nothing obstructing her view or covering the defendant’s face. The trial court also found the witness had previously identified the defendant in a lineup at which the defendant was represented by counsel who was present at all times pertinent. One person was excused from the lineup at the request of the defendant’s counsel, and all individuals in the lineup were similar to each other in age, build, and dress. Based upon these findings and others, the trial court concluded that the lineup was not im-permissibly suggestive. The trial court additionally concluded that the in-court identification of the defendant by the witness was of independent origin based solely upon what she actually observed during the attempted robbery and was not the result of any out-of-court confrontation or identification procedure. The evidence introduced on voir dire completely supported the trial court’s findings of fact which fully justified its conclusions. Therefore, the findings of fact and conclusions drawn therefrom are conclusive and binding upon appeal. State v. Tuggle, 284 N.C. 515, 201 S.E. 2d 884 (1974); State v. Davis, 33 N.C. App. 736, 236 S.E. 2d 722 (1977).
The defendant next assigns as error the trial court’s denial of his motion that the jury be instructed upon the law of attempted common law robbery and permitted to consider it as a possible lesser included offense of attempted robbery with a dangerous weapon. In support of this assignment, the defendant contends that the failure of the State’s witnesses to testify that the sawed-off shotgun used by the defendant was not a toy required such an instruction permitting the jury to consider the lesser included offense. We do not agree.
All of the evidence introduced indicated that the defendant committed a robbery with a sawed-off shotgun. There was no evidence indicating that the sawed-off shotgun was other than a real and functioning deadly weapon. Thus, there was no evidence tending to show an attempted common law robbery. Therefore, the trial court properly declined to instruct on attempted common law robbery or to permit the jury to consider returning a verdict *176on that lesser offense. State v. Evans, 25 N.C. App. 459, 213 S.E. 2d 389 (1975); see also State v. Davis, 242 N.C. 476, 87 S.E. 2d 906 (1955); and State v. Hicks, 241 N.C. 156, 84 S.E. 2d 545 (1954).
The defendant also assigns as error the trial court’s acceptance of the jury’s verdict as a verdict of guilty. The foreman, in attempting to return the verdict, first indicated that the jury found the defendant “guilty of attempted firearm.” The defendant contends that this was tantamount to a verdict of not guilty.
The foreman did experience difficulty in announcing a proper verdict. The trial court did not accept the verdict, however, until it was proper in form and indicated that the jury found the defendant guilty of attempted robbery with a firearm. Additionally, the trial court offered to have the jury polled. This offer was declined by the defendant. We, therefore, find this assignment without merit and it is overruled. State v. Rhinehart, 267 N.C. 470, 148 S.E. 2d 651 (1966); State v. May, 22 N.C. App. 71, 205 S.E. 2d 355 (1974).
The defendant next assigns as error the sentence imposed by the trial court. He contends that, as one Chester Melton had previously pled guilty to the same offense arising from the same robbery and been sentenced to imprisonment for a term of ten years, the trial court’s sentence of imprisonment for not less than twenty-five years nor more than thirty years in this case was cruel and unusual punishment and constituted a penalty for the defendant’s pleading not guilty and demanding trial by jury. This assignment is without merit.
The evidence clearly revealed that this defendant was the dominant of the two individuals committing the attempted robbery with a dangerous weapon. He was closer to the victim than the other man, directed the course of the armed robbery and personally pointed a sawed-off shotgun at the victim’s face from very close range. The clear danger to human life created by the defendant’s acts justified the sentence imposed.
Sentencing is a matter for the sound discretion of the trial court and is reviewable on appeal only where manifest and gross abuse of discretion is shown. No such abuse was shown in the present case. Although the trial court specifically indicated that the offense for which the defendant had been convicted would *177justify an even longer sentence, no greater sentence was imposed here than that imposed by the trial court after the defendant’s prior trial and conviction arising from this same offense. The prior sentence was nullified by our opinion in State v. Davis, 33 N.C. App. 736, 236 S.E. 2d 722 (1977), granting the defendant a new trial. Further, as the punishment imposed does not exceed the limits fixed by statute, it cannot be considered cruel and unusual punishment in the constitutional sense. State v. Elliott, 269 N.C. 683, 153 S.E. 2d 330 (1967). When a defendant believes his sentence to be excessive, although within statutory limits, his remedy is through executive clemency. State v. Baugh, 268 N.C. 294, 150 S.E. 2d 437 (1966).
Finally, the defendant assigns as error the action of the trial court in allowing Orrin Colson, a witness who had not been made known to the defendant previously, to testify as a rebuttal witness for the State. The defendant presents no arguments in support of this assignment, and we deem it abandoned pursuant to Rule 28 of the North Carolina Rules of Appellate Procedure. State v. McMorris, 290 N.C. 286, 225 S.E. 2d 553 (1976).
The defendant received a fair trial free from prejudicial error, and we find
No error.
Judges Parker and Hedrick concur.
