Alternut Drop-ins.
After numerous customer requests to design a drop-in barrel for the Remington Model 700 Shilen has done that and more by designing their NEW patent pending dual threaded Alternut System that will bring the ease and flexibility of drop-in barrels to even MORE platforms.The dual thread system was designed to increase the barrel diameter and wall thickness at the chamber end while still using a lock nut. To make things even easier for our customers these many configurations may use a Large Shank Savage lock nut. Alternut barrels come threaded and fully chambered to be installed into the action with no additional machining or modification needed.

The Alternut system is currently offered for:

Remington 700, 600, Model 7, 721, 722 XP-100
(The Remington's listed above must use recoil lugs measuring between .180" to .250")
Howa 1500
Weatherby Vanguard
Shilen DGR/DGV
More to Come!


All Alternut contours can be used on any of the Alternut platforms.
Some contours are a closer match to factory contours and will require less stock work.

  # A17 Remington Varmint Contour .830 @ 26"
  # A18 Remington Std Contour .650
  # A19 Remington Mag Contour .650
  # AS1 Bull Contour 1.00 @ 26"

  Shilen Chassis Contours Muzzle dia.
  # A7 Medium Contour .750
  # A8 Heavy Contour .875
  # A9 Extra Heavy Contour .940

See our Chamber page for available cartridge options. **NOTE: Alternut is NOT available in .585" boltface cartridges such as the .338 Lapua.**

We HIGHLY RECOMMEND that actual headspace gauges be used to determine if a barrel is properly installed and head spaced. In our opinion, this is the safest way to guarantee you will come back for more barrels.
