In excellent condition. Sig Sauer 556R SWAT Gen 2. OEM upgrades include chrome lined barrel, steel reinforced magwell, diopter sights, picatinny quad rail, and detachable cheek riser. Additional upgrades include, Shooting Sight match-grade trigger, Surefire 3P SOCOM flash hider, Hogue rubber overmold pistol grip with storage kit, and Krebs extended safety lever. Very low round count.  I’m happy to host a test-fire session for serious buyers at my local indoor range. Range fees not included.
