Our TAC21™ chassis system 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 hard anodized to mil spec type III for extra strenth, and has been finished with Cerakote™ in Black or Flat Dark Earth (FDE).
TAC21™ chassis is engineered to minimize warping and distortion. The rifle receiver only makes contact with the TAC21™ chassis on the V shape bedding and recoil lug area insuring the best accuracy and repeatability. The generous clearance on the fore-end makes any barrel (diameter up to the receiver size – 1.350”), free floating.
Inherently the TAC21™ has a straightline 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 comfort.
The TAC21™ 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)
