Building on decades of R&D, war, and commercial adoption, the REAP Scy taps into the vast and robust ecosystem of the AR-15/M4/m16, allowing you to build your ultimate rifle. The SCY Kit allows for use of tried and true AR15 style uppers and lowers of various lengths and calibers, giving you all the benefits of a Bullpup without any of the flaws. The only limit is your creativity. Rearward balance and a more compact package have several benefits: Shorter Overall Length compared to a traditional AR15 setup Maintain benefits of a longer barrel Less fatigue while in a shooting position Ability to effectively control the weapon downrange 1 handed while holding a dog, helping a teammate, manipulating doors, ATAK displays, etc. Shooter-centric weight balance allows for faster transitions, easier control Use Bufferless or Buffered AR uppers for Ultimate Modularity: -Bufferless options including the CMMG Dissent, Foxtrot Mike FM15, and more, allow for extremely compact rifles with a length of pull of just 14.5" when utilizing the Sickle stock. This means a 16" barreled SCY Bullpup build has roughly the same overall length as an 11" AR15, *without being considered an SBR (depending on state). -Buffered uppers work as well, and when utilizing the optional Stave compact stock system, have a length of pull of just 15.7", opening up an almost limitless pool of options and calibers. Incredible Trigger Feedback: Using our reliable, rigid, and low-friction trigger bar system, we can overcome the greatest flaw of Bullpups: poor triggers. Our system adds less than 1 pound of pull, while maintaining most of the sharpness and feel of your chosen AR trigger. *Length of pull: the distance between the trigger and the back center of the butt plate or recoil pad on a rifle. The average length of pull for an AR-15 is 13 inches Firearm shown in SBR configuration. All NFA rules apply. Package includes 1x Scy 1X Hardware pack 1x Mounting block
