The Noveske N4 Infidel Lo-Pro 13.7" 5.56mm Rifle is an elite, 4th-generation direct impingement semi-automatic rifle engineered for maximum tactical versatility without requiring NFA Short Barreled Rifle registration. Built on a matched set of billet 7075-T6 aluminum Gen 4 receivers with a clean Armor Black finish, this firearm utilizes a premium 13.7-inch 416R stainless steel barrel wrapped in a 15-inch Gen 4 NSR M-LOK free-floating handguard. The signature KX3 "Pig" flash suppressor is permanently pinned and welded to the muzzle, extending the legal overall barrel length to a non-NFA compliant 16 inches. The platform features an ambidextrous "Love Handle" charging handle, a pinned low-profile gas block, and a crisp, single-stage Noveske Smart Trigger (NSS). Handling ergonomics are completed with a comfortable B5 Systems Type 23 pistol grip and a multi-position B5 Systems Bravo adjustable buttstock.
