The CZ 455 Varmint Thumbhole is one classy rifle. Its stock, a nutmeg-colored laminate, is impressively ergonomic. The unique barrel uses the .866-inch profile of CZ's 455 Varmint barrels, but is heavily fluted to take some weight out. The receiver has integral 11mm dovetails for scope mounting. The single-stack detachable magazine holds five rounds of .22 LR. Adjustable trigger. 2-position safety. 1 in 16" twist.
