Product Details

Sig's specially marked duty short-barrel (SBR) cartridges feature a striking black-oxide brass casing to distinguish them, as they reach peak performance from much shorter barrels than the traditional Sig Elite Performance cartridges. These SBR brand cartridges are fitted with one of Sig's most devastating projectiles, the 205 grain 'tipped' 300 Blackout bullet. Sig has refined their 300 Blackout projectile shape to include a distinct shoulder that can make a significant difference when feeding from traditional AR magazines, as this shoulder allows the control surfaces inside of AR magazines to help feed ammo reliably instead of creating unneeded friction. 

  • Sig Sauer 300 Blackout 205 Grain Tipped Duty Subsonic SBR
  • Tipped bullet provides devastating expansion
  • Ideal for use with suppressed weapons
  • Ideal for use by police/law enforcement 
  • 1000 fps muzzle velocity

The expanding tipped bullet on these black-cased duty SBR cartridges comes from Sig's hunting line, where it is down to have staggering knockdown capability. With naturally subsonic speeds great for suppressors, optimization for 30-round AR-15 mags, and a powerful expanding bullet, these defensive 300 Blackout rounds from Sig SBR are a very excellent choice for duty and home defense roles. Make sure you pick up a box or two before these sell out!
