A Block II-style carbine on Daniel Defense's M4A1 FSP upper: a 14.5-inch barrel with a pinned-and-welded SureFire SF3P flash hider, so it is a 16-inch rifle. The fixed front sight post and KAC folding rear sight co-witness through an EOTech EXPS3, and a SureFire scout light and KAC vertical grip go on the RIS II quad rail. We swapped the source's ACOG and RMR for the EXPS3, a common Block II optic, to keep the sight picture simple. Check your state and local laws before buying. Inspired by: T.REX ARMS — 14.5" FSP Block II (https://www.trex-arms.com/loadouts/14-5-fsp-block-ii-232)
