Heckler & Koch USA is now offering a high-quality understudy to its AR-pattern center-fire rifles with a new version of the HK416 .22 LR chambered in .22 Long Rifle. Built in partnership with Umarex of Germany, the HK416 is designed to be one of the most realistic H&K-branded rimfire rifles available for sub-caliber training, small-game hunting or competition. Unlike some AR-inspired .22s, which employ a good deal of polymer in their construction, this rifle features an aluminum flat-top upper and lower receiver set. The M-Lok handguard is topped with a full-length rail. A functional forward assist, spring-loaded dustcover and last-round bolt hold open contribute to the appearance and operation of this rifle. Other features include adjustable folding combat sights, a retractable shoulder stock and a pistol grip with a storage compartment. H&K will be offering 10-, 20- and 30-round magazines for these rifles. hk-usa.com
