(Atlas actions are Remington® semi clone)


Description


The Atlas action is a Remington Semi-clone action, featuring a side bolt release and trigger hanger. This action can be easily fitted to any Remington 700/40x stock or chassis system with very little modification. The Atlas is made to extreme tolerances never heard of in a normal Remington action. The rear base is on a level plane with the front base, making it easier to have accurate alignment of optics.

Made of 416RS this action is very rugged and reliable. The bolt is made in house with 4140 alloy steel. We have designed the action to accept the AICS magazine boxes. We will accommodate the .223 and .222 rounds with a special magazine cut-out, please request if you intend to use one of these cartridges.

We use a 2-pin recoil lug on all Atlas actions, making a "bind" less likely to happen when changing barrels. Options for this action are single shot, magazine, fluted bolts, TG or Remington ejectors, and they are available in long or short action lengths.

Comes standard with:

Aluminum Bolt Plug Trigger Bracket and Screws • Rear Allen Head Guard Screw • Spiral Fluted Bolt • Aluminum Trigger Guard • Grease

Chambering Instructions


When chambering for a Panda, Kodiak or Grizzly barrel cut the tenon 1.0625” in diameter by 1.115” for a cone bolt action or 0.980” for a flat bolt action. For an Atlas barrel cut the tenon 1.0625” in diameter by 0.692” for a cone bolt action or 0.557” for a flat bolt action. It is recommended that the first 0.110“ from the rear of the barrel be turned to 0.966” diameter. Leave the rear end of the barrel square for now.

Thread the tenon 1.0625 inches in diameter by 18 threads per inch. If you are using the three-wire method to measure the threads, the measurement should be 1.0715” plus 0.0000“, minus 0.0020” using 0.032” wires.

For zero headspace on a cone bolt run the chambering reamer in until the head-space gauge is flush with the rear of the barrel. For zero headspace on a flat bolt run the chambering reamer in until the measurement from the base of the head-space gauge to the shoulder of the barrel is 1.115” for Panda, Kodiak and Grizzly actions or 0.692“ for Atlas actions.

For a cone bolt set the compound feed of the lathe to 30 degrees. Touch the tool to be used for cutting the cone at the chamber edge and lock the zeroed saddle stop against the saddle. Now back off the stop 0.135”. Using the compound feed only, cut the cone. This should give approximately 0.007” – 0.010” of space between the bolt and the barrel. On a 338 Lapua Mag. barrel the cone will cut away some of the length if a smaller diameter section is turned at the rear. This will leave the tenon closer to 1.089” in length with a 0.966” diameter rear section.

For actions with a removeable recoil lug add the thickness of the recoil lug to the tenon and headspace length. For example: an Atlas flat bolt action with a 0.250” recoil lug would have a 0.557“ + 0.250” = 0.807” tenon length and a 0.692“ + 0.250” = 0.942” headspace length.
