The CG DELTA Front Locking Action system DESCRIPTION

The CG Delta front locking action, internally know as  DELTA Model 59 in the C.G nomenclature is the front-locking counterpart of the now well know C.G. INCH rear-locking single shot Match action.

The basic Delta system is of a 3-lugs design in triangular shape. It is based on the Remington 700 Short Action footprint dimensions for the obvious reason of compatibility to numerous aftermarket accessories existing for this model, including stocks, triggers, but also magazines for the repeater models.

It is effectively offered in 3 versions and 2 variants:

-Delta NCT (Nickel Chromium Target) (unavailable)

-Delta NCR (Nickel Chromium Repeater) (unavailable)

-Delta LMT (Light Metal Target)

-Delta LMR (Light Metal Repeater)

-Delta LTT (Light Tube-stock Target)

-Delta LTR (Light Tube-stock Repeater)

-The Delta NCT. Single shot receiver, a massive tool steel unit with reduced openings. This model has 3 bedding screws, the front and rear ones being also at Remington S.A spacing, the third one being situated 1.500inch (38,10mm) behind the front one. This one is countersink to allow fitting of a underbelly spigot acting as a recoil lug, or used as a 3rd bedding point when bedded in the fleXibloc bedding system for instance.

-The Delta NCR. Repeater, receiver made from same tool steel. This model has an integral recoil lug positioned as the classic Remington one. This design had allowed for both models the adoption of a longer internal threaded length for barrel shank, with one cylindrical register, close to the INCH principle of barrel centering and interchange.

Both models are 34,50mm outside diameter (1.368&rsquo).

-The Delta LMT/Delta LMR Lightweight receiver , made of 7075 T6 aluminum alloy using at front a specific high-grade tool steel insert performing the important functions of bolting and barrel fitting and fixed into the receiver in a permanent and non-removable fashion. This combination of characteristics allow a very lightweight action with all the decorative finishes the aluminum alloy hard surface treatments and coatings permit.. Those lightweight receivers are 38mm (1.496inch) in diameter, but represent a considerable weight saving.

Bedding screws are also 3 for the Single Shot model, and 2 bedding screws for the repeater with integrated front recoil lug. Spacing&rsquos are same as for the NCT (3) -NCR.(2 with integrated recoil lug).

 


Extract from a blog by David Bonwick, The Shooting SHED UK

Now this is very interesting.

When I first heard of the latest Action from Robert Chombart/Action Clear my ears pricked up, Robert's work is always innovative and incredibly well executed and one thing you can be certain of is whatever he designs Action wise is going to be good. The results from the World Long Range Championships held at Brisbane in Australia last October are a bit of a hint as to what to expect from.

Yes, you will probably remember us Brits whipped the world in the Palma competition with South Africa second, the USA third and the host, Australia fourth with Canada and New Zealand following, however what were these guys shooting?

A careful analysis of the WLRC shows that Robert designed 51 out of the 96 Actions used by the Palma competitors, including the C.G-RPA2000 , RPA Quadlock , C.G Millennium, C.G INCH, this was between the six competing teams so over half the competitors were shooting a rifle with a CG Action.

Looking at the individual results 5 out of the top 10 were using CG Actions:

1st Richard JEENS (C.G Quadlock)

2nd André DU TOIT (C.G INCH) , also winning the Under 25 Worlds Champ.

4th Jane MESSER (C.G Quadlock)

5th Geoffrey GRENFELL (C.G Millenium)

7th Johannes DU TOIT (C.G INCH)

In fact it was 5 out of the top 7 but hey, who is counting!

So back to this Rem700 clone Action. Well it is certainly Robert's work, that is immediately apparent when you first see it and I was lucky enough to see the prototype whilst visiting Robert at the Imperial last month. The Action itself looks massively robust externally with an 85,0mm ejector port, the back end of the bolt is different when viewed in the receiver however it is when you remove the bolt you realise you are looking at something very new and different.

It has three lugs and is big, very big indeed, the bolt diameter is a massive 22,0mm as are the lugs, compare this to the standard Remington 700 bolt core diameter of 17,75mm/,700inch

Primary extraction of 2,0mm is by the bolt itself and the Action is supplied as standard with the CG Model 22 trigger. There are also two options for the firing pin spring, standard wire spring or Belleville washer giving a significant reduction in lock time.

Some pictures to whet your appetite.

The Action with standard Remington 700 floor plate

 

The Action with aftermarket bottom metal and yes that is an Accuracy International magazine, what else would you choose?

 

The bolt itself.

 

The bolt lugs, remember this is a prototype and has been built to confirm the drawings and function of the Action itself so some minor changes may be made before final release.

 

Yes I know the pictures are not great however when did you last see a prototype rifle Action at such an early stage so any wannabe Industrial Espionage types need not bother, here is the Action and near full specification.

The Action is to be produced by Chris Quartermaine of Action Clear in Western Australia who already produces the CG INCH Action and is well versed with the exacting tolerances required for such an Action.

The CG DELTA Front Locking Action system technical stuff:

DESCRIPTION: The CG Delta front locking action, internally known as the DELTA Model 59 in the C.G nomenclature is the front-locking counterpart of the now well-known C.G INCH rear-locking single shot Match action. The basic Delta Model 59 is a 3-lug design in triangular shape. It is based on Remington 700 Short Action footprint dimensions for the obvious reason of adaptability to aftermarket accessories existing for this model, including stocks, triggers, but also magazines for the repeater model.

It is effectively offered in 2 versions and 2 variants:

Single shot, a massive receiver with reduced openings. This model has 3 bedding screws, front and rear being at the Remington spacing, the third one being situated 1.500" (38,10mm) behind the front one. This one is countersunk to allow fitting of a "belly" spigot acting as a recoil lug, or used as a 3rd bedding point when bedded in the fleXibloc.

Repeater. This model has an integrated recoil lug positioned exactly like the classic Remington has. This design allows the adoption of a longer barrel shank for both models, with one cylindrical register, close to the INCH principle of barrel centering and interchange.

Both models are 34,50mm outside diameter (1.368").

A variant Lightweight receiver, made of 7075 aluminum alloy using at front a specific high-grade steel insert that performs the important functions of bolting and barrel fitting. This hardened tool steel insert is fixed into the receiver in a permanent and non-removable fashion which allows for a very lightweight action with all the decorative finishes the aluminum hard surface treatments and coatings permit. Those lightweight receivers are 38mm (1.496") in diameter but represent a considerable weight saving.

The Delta receiver accepts the Remington-style trigger holding. The improvement here is that it is fixed by screwed cross pins (instead of pressed-in) for an easy removal of the trigger.

Counter-lugs in the receiver are not broached but milled instead during the CNC machining process. This ensures a perfect concentricity and geometry.

The bolt is of the full diameter principle allowing a perfect and smooth motion. Guidance is ensured by the bolt stop lever itself, which retracts out of the raceway automatically at the end of the forward bolt stroke, when the lugs are already engaged, to allow bolt closure. At the end of the rearward stroke, the bolt stop lever also actuates the CG inertia ejector.

The bolt head is of 120° tapered silhouette, fitting very closely indeed into a corresponding female cone in the rear of the barrel. With this and the counter-lugs geometry in the receiver, the feeding of the cartridge into the chamber is without any hindrance whatsoever, and whatever the cartridge dimensions.

The firing mechanism is specific. All parts are fully machined and adjustable. The firing system is actuated indifferently by Belleville spring washers or by a conventional coil spring. Also, the firing pin can be either the C.G inertia double-tipped reversible tip or conventional one-piece. Cocking is of the shroud principle with the shroud closed at the rear for safety and easily removable from the bolt with no difficulty and no specific tools. Protrusion is pre-set but can be adjusted.

The bolt head shape allows the use of the wide extractor of the INCH. An Inertia ejector of the well-proven C.G, C.G Quadlock and C.G Millennium principle is standard.

The OEM trigger will be the CG Model 22 for Remington but any aftermarket trigger intended for this fitting can be used. The fitting of the trigger is by means of the two cross pins but the pins are fixed by screws for easy removal of the trigger for adjustment or maintenance.
