Semi-automatic .22 rimfire rifles configured to act as understudies for popular general-purpose rifles continue to grow in popularity. Walther has been a contributor to this market with models that emulate center-fire rifles like the Colt M4 and the Heckler & Koch (HK) MP5. This year Walther is offering a new .22 styled after the HK G36 5.56x45mm battle rifle. With a light-weight polymer chassis, the Walther G36 features a blow-back operated action, a fully-adjustable rear sight, an optics rail, and a removable flash hider. Customers will have a choice of 10, 20, and 30-round box magazines. Watch the video here, and for more visit Waltherarms.com.
