Barnard Model GP Action

This, the latest member of the Barnard family of actions, is designed for the largest of cartridges that are generally found in use in target rifles.

The Model GP is of conventional, cylindrical  forward-locking turn bolt design, is available in either left or right handed configuration and at present time is only single shot format. Supplied with the action is a 6061 aluminium bedding block, an anodised 6061 aluminium piccatinny style scope rail (30 minutes of angle), and Barnard trigger. The bedding block can be used with (recommended), or without a 12mm recoil stud which is also included. This bedding block is machined to give 2 parallel points of contact on the receiver which will ensure excellent alignment and rigidity when mounted well in your stock.

The receiver is a massive 4340 chrome/moly/nickel steel solid bottom cylinder, with relatively narrow load/unload port which is through hardened to 38Rc and finish machined after surface hardening to ensure concentricity.

The bolt carries three forward locking lugs, is equipped with a Sako style extractor and bolt face which can be supplied to accept any case rim up to 0.804".  It too undergoes finish machining after hardening, and is hand lapped to suit its mating receiver.


This action accepts a standard Barnard target trigger similar to the trigger supplied with the 'P' range of actions. It will accept cartridges up to an overall length of 5.50" - thus will handle any of today's popular large bore cartridges.
