Slab’s Takur Ghar blaster
Found in the NHHC Curator Branch Collection: This rifle was carried by then-Senior Chief Britt “Slab” Slabinski while serving as Team Leader of Maco 30 during the Battle of Takur Ghar in support of Operation Anaconda.

Lots of pic rails, standard A2 grip, no suppressor. But this is no Mk18– look at the magwell, that’s an AR-10, specifically a Rifle, Sniper, 7.62MM, MK 11 Mod 0 (SR-25)
Op Anaconda was the first major ground combat operation in Afghanistan during Operation Enduring Freedom. Master Chief Petty Officer Slabinski was awarded the Medal of Honor May 24, 2018 for his actions in Afghanistan during Operation Anaconda in 2002.
