Ruger SR-556 Takedown Barrel Kit 300 BlackOut 16″, 2 30 Rd Mags

The Ruger Mark IV Target is a simple, blowback-operated pistol based
on the original Ruger Standard introduced in 1949. Unlike its’ predecessor, however, the Mark IV
Target features one-button takedown for quick and easy
field-stripping and proper chamber to muzzle cleaning. A recessed
button in the back of the frame allows the upper receiver to tilt up
and off of the grip frame without the use of tools. It features a
one-piece, precision CNC-machined grip frame, ergonomic bolt stop,
and a contoured ejection port. The sighting system features an
adjustable rear sight and a receiver drilled and tapped for Weaver-
or Picatinny-style rail (rail not included). The ambidextrous manual
safety positively locks the sear in the “SAFE” position
when applied, and the safety can be converted to left-side only with
included washer. This model includes two 10-round magazines.
