TAC21 Remington 700 Chassis

The TAC21 Remington 700 chassis is a combination of bench rest accuracy, superior ergonomics and specialized design. This chassis brings the Remington 700 to the next level in versatility and modularity, with an instant improvement in accuracy.

The drop-in chassis serves as a base to which the operator can add tactical components according to the desired functionality. The stock is manufactured out of aluminum hard anodized to mil-spec type III, with a top full length MIL-STN-1913 accessories mounting rail. The built-in mounting rail has 20 MOA (Minutes of Angle) on the action housing and is parallel to the barrel axis on the fore-end.

The TAC21 Remington 700 chassis is designed to accept any AR-15 butt-stock and pistol grip (purchased separately), offering the option to customize from the wide variety of accessories available on the market.

The TAC21 Remington 700 chassis uses AICS style magazines in .223 and .308 caliber for Short Action and .300WM or .338LM magazines for Long Action rifles, and supports installation of bolt on MIL-STN-1913 accessory mounting rails on the fore-end and side of the action housing. Mounting holes are spaced for Magpul style L5 (11 slots) and L3 (7 slots) rails (1.600” / 3.200”).

The TAC21 Remington 700 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.

Note: Long action magazines come in 3 different lengths: 3.715″, 3.775″ an 8.050″. The chassis use 3.715 magazines. If you purchase the Remington 700 Tactical Chassis Rifle, the magazine well is 3.775.
