American Rifle Company
Nucleus® Gen 2.0
American Rifle Company is proud to introduce the Nucleus Gen 2.0 bolt action.
We decided to update the Nucleus for two reasons. First, and perhaps most importantly, is reducing the elapsed time between order placement and fulfillment. To that end, an effort to improve production throughput was made by reducing the number of unique parts that we must manufacture. For example, the entire striker assembly of Nucleus G2.0 is now identical to that of the Mausingfield while its bolt head and the extractor are now identical to those of the Archimedes. And secondly, we want to give you more of what you want so Nucleus G2.0 has been updated with the following:
Keyed rail interface
For scope mounting, Nucleus G2.0 uses a Picatinny rail that now has a tapered slot that engages a similarly tapered key machined into the top of the receiver, just like those of the Archimedes. So, in addition to the five conical head screws that were used on the original Nucleus, the key provides an additional constraint for maintaining alignment between the rail and the receiver and for resisting the forces imparted on the rail by the recoil lug during barrel installation.
Bayonet style bolt shroud
The striker assembly of Nucleus G2.0 can now be removed by depressing the bolt shroud locking pin and then rotating the bolt shroud with respect to the bolt by one-quarter of a revolution, enabling tool-less take-down of the bolt for cleaning and for bolt-head exchange.
80 degrees of bolt rotation
In order to improve the smoothness of the bolt cycle, maintain an appropriate level of cocking effort, and still provide adequate clearance between the shooter’s hand and the scope during bolt cycling, Nucleus G2.0 has 80 degrees of bolt rotation. The original Nucleus had 72 degrees.
Smoother cocking and closing
Nucleus G2.0 slightly over-cocks when lifting the bolt handle and then de-cocks by a tiny bit when closing the bolt, thus no cock-on-close will be the standard offering. Moreover, the cocking piece never falls into the cocking cams when closing the bolt thus eliminating any bump-on-close that would otherwise result from a slight amount of re-cocking. The cocking behavior of Nucleus G2.0 is now essentially identical to that of our current Mausingfield action.
Optional cocking pieces
To accommodate variations among triggers that will be used within Nucleus G2.0, we now have an inventory of cocking pieces varying by 0.25mm (0.010 inches). Additionally, those wishing to enable their action to cock-on-close can do so by ordering a cocking piece that will provide that functionality. Cock-on-close cocking pieces can also be modified by a competent gunsmith in order to eliminate any de-cocking and cocking-on-close.
The smartest bolt knob in the industry
Nucleus G2.0 comes standard with our short barbell knob which we believe is the smartest and most ergonomic bolt knob available. The knob boasts a function driven design that makes high-speed cycling of the bolt as easy as possible.
Improved fully-retracted bolt guidance
The receiver of Nucleus G2.0 cradles more of the bolt body than did its predecessor, thus making it a bit easier to avoid binding while cycling a bolt that was already easy to cycle. An incremental improvement at best, is was easy to implement and therefore we included it.
During the past few years, we have struggled to deliver actions in a timely fashion. Afterall, coaxing a bolt action out of a hardened steel bar is not easily done. We often underestimated just how difficult it is to do this stuff. So rather than introduce something completely new like we did last year, American Rifle Company’s goal for 2020 is to significantly reduce the time it takes to put our products in your hands by getting better at what we do. Nucleus G2.0 is a big step in that direction and we will begin taking orders and deposits for these soon.
And as always, thank you for your business. It's the fuel that keeps us going and we don’t forget that.

So, what is a Nucleus Gen 1.1 and why is it on sale?
A Nucleus Gen1.1 is essentially a Nucleus Gen2.0 less the keyed rail interface and the extended support for a fully retracted bolt. Apart from that and the use of the Gen1 bolt head, the two are functionally identical.
During the development of Nucleus Gen2.0, we had to decide what to do with some existing Gen1 inventory of which we did not have enough to build complete Gen 1 actions. We decided to rework Gen1 receivers and fit them with bolts that are nearly identical to those of Gen2.0 yielding Gen1.1 actions having Gen2.0 functionality. Doing so presented us with the smoothest transition to Gen2.0 which we developed to apply lessons learned and to improve production throughput and availability of all of our actions. Gen1.1 fit nicely into this line of reasoning.
Nucleus Gen1.1 upgrades include the following:
Bayonet style bolt shroud
The striker assembly of Nucleus G1.1 can now be removed by depressing the bolt shroud locking pin and then rotating the bolt shroud with respect to the bolt by one-quarter of a revolution, enabling tool-less take-down of the bolt for cleaning and for bolt-head exchange.
80 degrees of bolt rotation
In order to improve the smoothness of the bolt cycle, maintain an appropriate level of cocking effort, and still provide adequate clearance between the shooter’s hand and the scope during bolt cycling, Nucleus G1.1 has 80 degrees of bolt rotation. The original Nucleus had 72 degrees.
Smoother cocking and closing
Nucleus G1.1 short-action slightly over-cocks when lifting the bolt handle and then de-cocks by a tiny bit when closing the bolt, thus no cock-on-close will be the standard offering. Moreover, the cocking piece never falls into the cocking cams when closing the bolt thus eliminating any bump-on-close that would otherwise result from a slight amount of re-cocking. The cocking behavior of Nucleus G1.1 is now essentially identical to that of our current Mausingfield action. Note that the Nucleus Gen1.1 long-action may exhibit a slight bump-on-close that is much less perceptible than that of the original Gen1 Nucleus. If you are hypersensitive to the sort of thing, we suggest choosing a Nucleus Gen2.0 long action.
Optional cocking pieces
To accommodate variations among triggers that would otherwise change the way the bolt cycle feels to the user, we now have an inventory of cocking pieces varying by 0.25mm (0.010 inches) for the Nucleus G1.1. Additionally, those wishing to enable their action to cock-on-close can do so by ordering a cocking piece that will provide that functionality. Cock-on-close cocking pieces can also be modified by a competent gunsmith in order to eliminate any de-cocking and cocking-on-close.
The smartest bolt knob in the industry
Nucleus G1.1 comes standard with our short barbell knob which we believe is the smartest and most ergonomic bolt knob available. The knob boasts a function driven design that makes high-speed cycling of the bolt as easy as possible.
Currently available are about 133 Nucleus Gen1.1 right-handed actions of which 97 are short-actions and 36 are long-actions. These actions are fully assembled and ready for immediate shipping once we receive payment and your FFL details.
So come and get’em! We want to clean our slate so that we can usher in the era of Nucleus Gen2.0 sooner than later.
And as always, thank you for your business. It's the fuel that keeps us going and we don’t forget that.
And again, customers with pending orders can choose from either the $795 Gen 1.1 or the $1000 Gen 2.0
