This is a new PWS MK112 Mod-1M in 300 blackout. It has a 12.75” barrel and is entirely PWS except for the Magpul brace and Crosstac muzzle brake. Comes with one 30 round mag. This model has been discontinued and was only produced for a very short period. This is a long stroke piston gun with an adjustable gas system for shooting subsonic or hypersonic rounds, as well as the ability to shut the gas system off in order to have a single shot when suppressed. Super nice and originally over $1700 when available. Must meet around Garland/Mesquite area. More pictures available upon request. Make offer. Thanks
