Mayfair Engineering Mauser actions are a combination of the very latest Computer Aided Design (CAD) and manufacture, together with the very finest in traditional gunsmithing.

Actions are made in magnum Mauser, standard and short, either in left or right hand. All lengths are available in either double square bridge, single square bridge or the standard round action.

The components for these actions are machined from solid bar stock using only certified materials at our own workshops in England, allowing total quality control. Each action and magazine is individually tailored to the particular calibre.

The company’s philosophy of attention to detail has been used to good effect with a full understanding of the essential features of the original design. Mayfair actions are engineered to suit both modern and traditional calibres with no compromise on feed and function.

The foundation blocks on which Mayfair Engineering was builtwere those of the bolt action rifle, so it is not surprising that the Company has returned to where it began and has now decided to produce the world’s most exquisite bolt action, with no compromise and with no short cuts - that of the Magnum Mauser bolt action.

With many years of experience within the weapons industry, Mayfair’s meticulous attention to detail and lack of compromise has ensured that the world’s finest rifle makers have chosen to create their rifles on what is considered to be the world’s finest action.

Mayfair Engineering has been designing and manufacturing fine gun and rifle actions for the ‘best gun’ trade for more than 20 years and specialising in designing, prototyping and manufacturing proprietary shotguns and rifles alongside providing design solutions for military weapons systems.

Mayfair Engineering has led the way in the introduction of modern technology and manufacturing techniques within the ‘best British gun’ industry, having done a great deal of outwork for many of the great British gunmakers.

Not afraid of using modern powerful design software, the true art of gunmaking is never forgotten with the traditional elements still a key feature in any design.



As with the receiver, each bolt begins with a stress relieved billet of 8620 steel and is painstakingly machined to produce Mauser's legendary bolt with dual opposed front locking lugs, a top guide lug and third safety lug, possibly the world’s strongest and safest bolt configuration. Mayfair Mauser bolts are supplied as standard with a ‘scope cutout on the handle. However, bolts can be supplied without cutout upon request. All bolts come fully case hardened.

The heart of a Mayfair magnum Mauser - the receiver. Each one is individually machined from a solid block of stress relieved 8620 nickel-chromium-molybdenum steel, utilising state of the art CNC machining and Electro Discharge Machining, before being hand finished and lapped to produce what we consider to be the ultimate bolt action. Receivers are available in short, standard and magnum lengths, double square bridge, single square bridge or the classic round action, right hand or left hand.



3-position side safety is standard on all Mayfair magnum Mauser actions: an essential requirement if using telescopic sights.

Bottom metals for Mayfair magnum Mausers are machined from a solid block of 070M20 certified steel. Each bottom metal is manufactured for a particular calibre. Trigger guards can be supplied in either of two styles (Hunter or Safari) and all bottom metals are machined with a 4° inclusive draft angle around the entire profile to allow for ease of inletting and weight reduction. Hinged floor plates are opened by means of a push button release.



Mayfair has been very careful to incorporate the very finest features of the Mauser design, not least in the machining of the magazine and magazine opening. Our attention to detail addresses the correct lengths and widths for the calibre, incorporating the complex machining of the shoulder cutouts and angles in both the magazine box and the receiver underside to ensure perfect feed and function.

The classic Mauser full length extractors are machined in three different lengths from a solid bar of silicon manganese spring steel for unsurpassed strength and reliability.


The magazine followers, together with all other components of a Mayfair Mauser, are machined from solid bar stock using the very latest CNC machinery and all production is carried out at our own workshops.


All action lengths and sizes are available, as standard, in either right hand or left hand.

Only with meticulous attention to detail and after extensive quality checks will a Mayfair action be stamped and released for use.
