Barnard Model SM Action

The Model SM repeating action is a derivative of the Model S. This action is configured to accept a 5 or 10 round HS Precision magazine, Accuracy International magazine or AICS magazine with floor furniture / bottom metal.

A safety cut option also available for this action to allow top safety Jewel and Timney triggers.

Like the Model S it is a cylindrical Remington type action with the same diameter receiver, mounting screw positions and bolt turn position as the Remington 700 short exterior configuration. But in the Barnard three lug configuration and so “not a drop in” for the Remington 700.

As a three lug action the arc of bolt operation is shorter and the port is a different size and position. The length of the action is 10mm longer at the barrel end than the Remington 700 short action. For a detailed view click here.

The S series actions were designed as target actions to take Remington 700 aftermarket triggers etc. they are more often than not fitted into Remington style Stocks. Very little work is needed to have the action fit the various 700 stocks.

The action receiver is of 4340 chrome/moly/nickel steel through hardened to 38Rc and finish machined after surface hardening to ensure concentricity. The bolt is casehardened EN39b, ground and machined after hardening to ensure straightness and concentricity. The bolt lugs are hand lapped to the matted receiver. Sako Type extractor and is equipped with a bolt face plunger style ejector.

We supply this action with a trigger hanger to suit either Timney or Jewel triggers, or with a blank hanger to be modified to the trigger of your choice (such as any “Remington style” clone). This action is supplied as standard with no trigger, but please specify which hanger you require when ordering.

This action is also available in a complete rifle – the Barnard ’07’

Recoil Options

The Model S has two options available to handle recoil:

  • a Remington type lug between receiver and barrel
  • use of a recoil spigot from the action (1/4″ X 28 cap screw with the head machined concentric) which fits into a steel bushed hole in a 6061 aluminium bedding block that has been machined to provide 2 parallel points of contact on the action.
