High-tube adapters have a comb height equivalent to an AR-15 and require an optics rail (included).
High tube adapters allow proper cheek weld and eye alignment with popular optics such as an ACOG or Leupold CQT and others.
Our complete stock kits include the aluminum AR adapter; Hogue rubber overmolded grip; US-made mil-spec six-position M4 SOPMOD style telescoping stock assembly; and all necessary assembly hardware and instructions.
