This is a switch barrel system and it takes 90s or less to change from one caliber to the next.
Pictured is the .308 barrel (installed), the 6.5 Creedmoor barrel, .300 Winchester magnum conversion kit, and the .338 Lapua magnum conversion kit.
It also came with a 34mm optic mount (30 MOA), a Thunderbeast CB brake on each barrel, (2) boxes of .300 WinMag match ammo, and (1) box of Federal Gold Medal Match .338 Lapua ammo.
The .308 has had 200rds through it, the 6.5 has had 300rds through it, the .300 WinMag has had 60rds through it, and the .338 Lapua only 20rds.
I practically stole this setup for $5300, which is less than half of retail.
