Cooper Arms Model 21 LVT (Long Varmint Target) in 223 Remington. The LVT configuration applies a heavier, sporter-varmint barrel profile to the Model 21 short action for improved accuracy during extended prairie dog sessions. Same three-rear-lug action and sub-half-MOA guarantee as standard Model 21, but with additional barrel mass to reduce point-of-impact shift as the barrel heats. The 223 Rem LVT is the benchmark production varmint rifle. Type: Rifle Action: Bolt-Action Caliber: 223 Remington Capacity: 1 Year introduced: 1993, USA Weight: 65 oz Overall length: 44" Status: Active Intended use: varmint hunting, target shooting
