KELBLY ATLAS TACTICAL ACTION

The Atlas Tactical action is a Remington semi-clone action, featuring a side bolt release and trigger hanger. Minimal modification is required to use a Remington 700/40x stock or chassis.

We have created the most rugged action possible for practical, tactical, or hunting use. We utilize a Black Nitride finish from H&M Metal Processing, which allows you to use this action “dry” or without lubrication for extreme environments. As always, it is best to use lubrication in day-to-day shooting. In addition to the Black Nitride process, we use a fluted bolt to help move dirt into the flutes, allowing better function of the action.

We have cut the magazine well to use the Accuracy International single stack magazines. One of the key features of this action is the TG ejector, which is a mechanical ejector that does not put any chamber pressure on the round. It is also a “never fail” setup, meaning there are no springs to get gummed up and stop working.

We offer an Extreme Duty Bolt Stop, which bolts to the side of the action via a 6/48 screw. It is truly the most reliable bolt stop upgrade on the market!

We finish it off with a pinned 20 MOA Picatinny 1913 MIL-SPEC rail, a dual pin recoil lug, and a tactical bolt knob.

• When chambering for a Panda, Kodiak, or Grizzly barrel, cut the tenon to 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 to 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” in diameter. Leave the rear end of the barrel square for now.

Threading the Tenon: 1.0625” diameter with 18 threads per inch. If 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.

Lathe Setting for 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 only the compound feed, cut the cone. This should give approximately 0.007” – 0.010” of space between the bolt and the barrel.
