*Price Includes P&W with a KAK Extended Flash Hider, Any device available upon request*
The MK3s is a MK3, but shorter. The 13.9" barrel still has the ability to P&W to a legal 16" length while still being a very handy vesatile length. The Hanson barrel profile is factory pinned and very efficient for its weight.
Each upper ships with a unique checklist noting the ejection pattern with brass cased ammunition, function, lock back on empty, and any buffer/spring recomendations I may have.
