Looking for a stock replacement for your Remington 700, Savage or Tikka T3 Bolt action rifle, turning it into a tactical and highly accurate system? Our TAC21 Gen2 Chassis system for bolt action rifles offers a combination of improved accuracy, superior ergonomics and specialized design allowing use of AR-15 butt-stocks, grips and automatically converts your rifle to an external box magazine fed rifle. The TAC21 Gen2 can be installed in 30 - 45 minutes without the need of bedding and has proven results with up to 28% accuracy improvements. Our TAC21 Gen2 chassis system is a combination of benchrest accuracy, superior ergonomics and specialized design. This chassis brings the bolt action rifles to the next level in versatility and modularity, with an instant improvement in accuracy. The chassis system is manufactured out of billet 6061-T6 aluminum, which has been finished with Cerakote in Black or Flat Dark Earth (FDE). TAC21 Gen2 chassis is engineered to minimize warping and distortion. The rifle receiver only makes contact with the TAC21 Gen2 chassis on the V shape bedding and recoil lug area insuring the best accuracy and repeatability. The generous clearance on the forend makes any barrel (diameter up to the receiver size 1.350) free floating. Inherently, the TAC21 Gen2 has a straight-line design, meaning that the recoil comes straight back instead of making the front of the rifle kick upwards. This results in more accurate and quicker follow up shots. This also translates to a decrease in felt recoil and increase in comfort. COMPATIBILITY The TAC21 Gen2 chassis system is currently manufactured for the following bolt action rifle platforms: Remington 700 Short Action (.223 and .308 bolt faces) Remington 700 Long Action (.300WM, .338LM, 7mm RM, 30.06) Savage Short Action, Models 10, 11, 12 and 16 (.223 and .308 bolt faces) Savage Long Action, Models 110, 111, 112 and 116 (.300WM) Tikka T3 - Short Calibers (.223 and .308 bolt faces) Tikka T3 - Long Calibers (.300WM, 6.5x55, 7mm RM, 30.06).
