Description
The TAC30 actions are designed for tactical use. They can also be used for long range hunting.
They are bead blasted 416R stainless and are Remington 700 footprint. The TAC30 will fit any stock with a Remington short action inlet. TAC30 actions are available with 223, 308 and magnum bolt faces. The 223 bolt face uses the Sako style extractor, while the others use a modified M16 type. The magazine cutout is the same as a Remington 700. They have #8 screw holes for scope base mounting. One piece picatinny rails with 0 or 20 moa cant are available. All tactical actions feature a screw-on bolt knob. The bolts have a new proprietary coating that makes them as smooth as glass.
