Bushmaster .223 Flat Top Varminter 24″ Fluted Matte Barrel AR Upper Receiver 92820


Category: Product ID: 1711



Bushmaster 92820 Flat Top Varminter 223 Rem/5.56 NATO Gauge 24 in Fluted Matte

This complete upper assembly features a 24 in Fluted Extra Heavy Barrel in 5.56mm/.223 Rem. caliber with 11 degree competition crown; heavyweight 1 in diameter under the handguard; custom match hybrid chamber with a tighter SAAMI Spec headspace from the shoulder of the chamber to the bolt face, and longer chamber throat or Leade in . This accommodates 5.56mm ammunition without developing higher pressures encountered when firing 5.56mm ammo in a .223 chamber with shorter Leade in (both calibers can be used safely). Rifling is 1 in 9 in twist for optimum performance with most lighter bullet weight varmint cartridges, and the barrel is fluted to increase cooling and reduce weight. The Varminter Upper’s shell ejection path has been modified to drop all your brass in the same place as a convenience for the reloader. A vented forend with bipod/sling stud installed, free-floats the barrel from the barrel nut forward and B.M.A.S. Mini-Risers add 1/2 in to scope height for correct sight picture and comfortable cheek weld. This Upper is sold complete with Bolt, Bolt Carrier and Charging Handle to ensure positive lockup between bolt and barrel extension.
