SERAPH s1K SCRS Assembled Upper
The s1K barreled upper receiver group build features a 7075-T6 aluminum forged threaded upper receiver matched to a SERAPH Crucible Rail System (SCRS), housing a 12.8″ mid length 4150 CMV Patrol+ nitride barrel in a selection of calibers. This milspec AR15 upper is built by hand in the legacy of the s16, its larger competition counterpart, and can be paired with any milspec and most milled lower receivers. Engineered to be faster, lighter and more agile, the s1K upper represents the competitive ancestry of our mission applied to personal defense and home protection by strategically making a nominal sacrifice of traditional carbine rifle ballistics to offer a design tailored to excel at CQC in urban environments, home defense and community protection scenarios.
