Noveske 02001231 N6 Gen 4 Leonidas 7.62x51 12.5" Micro Switchblock SBR Black

The Noveske N6 Gen 4 Leonidas is a 7.62x51 short-barreled rifle built around a 12.5-inch 416R stainless steel barrel and Noveske Micro Switchblock gas system. The three-position Switchblock provides dedicated Unsuppressed, OFF, and Suppressed settings, giving the rifle a purpose-built gas-control system for different operating configurations.

The 12.5-inch barrel uses a 1:10 twist, hand-polished Noveske Match Chamber, extended feed ramps, and 5/8x24 muzzle threads fitted with a Noveske Pig Pen muzzle device. A proprietary Leonidas gas tube and pinned .750-inch Micro Switchblock complete the barrel and gas system.
