Matador Arms MAT-9K Features The MAT-9K is built around a roller delayed operating system paired with a 5.5 nitrided barrel reducing recoil and lightening the upper receiver while increasing overall reliability. The bufferless design and non-reciprocating reversible charging handle give shooters flexibility in how they run the platform while the Last Round Bolt Hold Open mechanism improves efficiency during reloads. For shooters who need consistent performance under rapid fire this operating system delivers smooth cycling shot after shot. The lower receiver features ambidextrous controls including an ambi mag release and safety selector along with an upgraded mil spec trigger and Type 3 anodized aluminum construction for long-term durability. The upper receiver includes a 1913 rail rear end for folding stock applications and the included A3 Tactical Folding Stock Brace adds a QD mount and 7.75 aluminum offset shaft for a stable adaptable shooting platform. For shooters who want a pistol that adapts to their preferred configuration this ambidextrous layout and folding brace system offer versatility without added bulk. The Matador Arms MAT-9K is finished with a Matador Arms long beavertail grip for a secure comfortable hold during extended shooting sessions. Backed by a lifetime warranty and built by a veteran owned and operated company made in the USA this pistol reflects a commitment to quality and reliability.
