This like new .22LR, 5 1/2" bull barrel, catalog no. MK-512 has only had one clip fired through it. Since then it's been in and out of my safe for annual cleaning. Beautiful weapon. Someone should use it! Comes with an unused Proline molded leather holster, original box and one clip. Please see the detailed photos and ask for any additional views you wish. $375 The federal and state firearms transfer laws will be complied with. Thanks, Jake35 SOLD.
