Barrels

Barrel material is Ultramet 6001, a special high strength ordinance grade nickel-chrome alloy having superior ductility for optimum ballistic performance, while providing excellent corrosion resistance.

The chambers are chrome lined to resist fouling and corrosion. Bores, however, are specifically not chromed to maximize the ductility of the Ultramet 6001.

Bore diameters are 18.8 mm (.740") for optimum ballistic performance.

The A&S oversized bores produce superior patterns without sacrificing wall thickness or barrel integrity, unlike back boring of standard dimension barrels. Other factory-overbore barrels are appreciably heavier than their own comparable standard bore barrels. Because of our special design and Ultramet 6001 alloy, barrel weight remains correct, with no degradation of proper swing and balance.

To limit shot deformation forcing cones are 88mm (3.5"). No additional advantage can be gained by extending them further. Also, to limit deformation, bores are carefully polished to the finest finish level practical. This finish is visually discernible in a perfectly clean bore when compared with other well known guns where faint tool marks appear as a diffraction grating when held to light.

Unlike other shotguns, wear points are hardened. Hinge surfaces on the barrel, where the barrel mounts to the receiver and the locking lugs on the chamber face where the locking bolt engages the barrels are carefully hardened. These areas wear and cause the need for installation of oversize hinge pins or the installation of an oversized locking bolt when the gun is used extensively. Because of this selective hardening, the life of the gun is greatly extended, and its value preserved.

Ballistic performance varies widely with shell, shot, or load selection. Because of this A&S provides the optimum barrel and choke environment to get the most out of any load chosen. The most stringent standards are applied to point of impact. Every barrel set is certified to these standards. Each barrel set is carefully shot for point of impact to assure accuracy of placement and commonality between the two barrel tubes. Any barrel set failing our rigorous standards is rejected.
 

Choke System

The barrels are available with conventional choking or our specially designed Astrochokes. The Astrochokes have been designed to eliminate all negative factors associated with interchangeable chokes. An Astrochoke tube is 88 mm (3.5"). The actual choke length is greater than a conventional in-the-barrel choke. Since the Astrochoke is designed solely for the A&S bore diameter, we are able to eliminate the typical transitional jump from the bore to the conical section of the choke.

There is virtually no jarring of the shot as it comes out of the bore into the choke cone. The choke is polished to the same level as the bore, unlike other choke tube systems; once again, to minimize shot deformation. Further, regardless of constriction, the conical section is constant at 2.875", maximizing pattern quality for any given shell. With regard to concentricity, because of the choke tube length, any misaligned boring or loose tolerance is visually magnified and the barrel is rejected in the manufacturing process.

The Astrochoke system, then, is literally the equivalent of spare barrels, in fact, it can be superior to spare barrels in as much as the weight and swing characteristics are always the same. Astrochokes, because of their design, do not require the muzzle of the gun to have the unsightly flare and additional weight common to most factory choke tube installations. So the elegance and balance of the gun is maintained. These special chokes are made by Briley of 17-4 PH stainless steel and are suitable for use with steel shot, observing normal, well known, industry cautions.
 

Receiver Barrel - Locking System

The system selected for all A&S over-under guns is the Boss-Woodward type. This is the system found on the world's best guns. It is characterized by "side fasteners". These are bifurcated lugs on the sides of the barrels that interlock corresponding lugs on the inside walls of the receiver. This system intersects the force line between the hinge pins and the barrel locking lugs, and absorbs much of the load during firing; thereby augmenting the work of the hinge pins and the locking lugs. This major additional locking system greatly extends the life of the other two systems, creating the most robust barrel locking system available.

Strengthening Against Wear In keeping with the strengthening of wear points, the forearm attachment mechanism has a replaceable wedge which works against the lug on the barrel. Should the lug wear to the point of the forearm becoming loose, this wedge can be replaced, the forearm then is made tight once again.

On standard grade A&S guns, the receiver and forearm metal are case hardened then hard chromed. This makes an extremely strong and corrosion resistant gun, which is virtually impervious to wear of any kind, plus it eliminates gas-cutting on the breech face and peening around the firing pin holes, common to many guns.
 

Strengthening

On the detachable trigger assembly RX model, the trigger housing loop of the receiver has been made significantly larger and more rigid to eliminate flexing. The tail of the trigger plate and loop are tapered at the back to eliminate stock cracking around the back of the trigger assembly, common to similar action types. The stantion between upper tang and housing loop is large and shaped to allow accurate stock bedding, again, to extend gun life. Further, this stantion is stronger and solid, not weakened by machining into it to carry other parts as is seen on other similar guns. This eliminates cracking of the stantion, not uncommon in other brands.

The top lever shaft which moves the locking bolt is held in the receiver not only at the top end but additionally at the bottom end where it is supported by a replaceable bearing sleeve.

Rather than a small pin at the base of the top lever shaft to operate the locking bolt, a robust separate camming piece is keyed to this shaft, making the whole system many times more durable and far stronger than might ever be required.

The trigger housing, unlike other detachable trigger guns, bridges from one side to the other at the top tying the sides of the housing together for added strength and permits the trigger assembly to be locked in place not only by the housing loop but at the top by the upper tang.
 

Superior Firing Mechanism

Hammer faces are specially radiused to minimized drag on firing pin travel, and firing pin angles are reduced. These design improvements maximize energy transfer and relieve angular forces which tend to break firing pins.

Hammer weight and length are minimized for rapid acceleration and short lock time. Hammer sweep is a mere 19 degrees. As on many sidelocks, the hammer springs on the RX boxlock are 'V' springs and act directly against the hammers to minimize the mass requiring acceleration during firing. This is obviously somewhat esoteric; however, it gives some insight as to the extent to which A&S has gone to give the best possible performance.

The 'V' springs give excellent performance in the A&S. They are at rest when the hammers are "down". Because they are shielded by their location in the mechanism, and, stored with hammers down, their life is extended greatly over other guns where the 'V' springs are constantly under tension. A special cut-away section of the trigger housing allows removal or installation of these hammer springs without further disassembly of the mechanism.

Sears are uniquely counterbalanced permitting very light trigger-pull setting and preventing jar-off doubling with even the heaviest loads.

Triggers are available both selective and adjustable for position. Both systems are designed to eliminate operator error. The barrel selection does not require the safety to be "on" when making a selection, as with other guns. Simply push the button and selection is made. Moreover, with this type of selector, A&S has eliminated the possibility of "tricking" the selector causing the gun to double.

Trigger pulls are crisp and positive - without drag. This is due to the trigger pivot-point to sear-trip relationship, which has been optimized. Further, sear engagement is minimal as on most fine sidelock guns, making sear-off imperceptible.
 

Passive Ejector Trip System

Most selective ejector guns set the top or bottom ejector to fire by the hammer striking a rod which passes through the action and, under the heavy force of the hammer spring, is held out to trip the ejector sear when the gun is opened. This causes wear-and-tear on the ejector system, and reduces the driving force of the hammer against the firing pins. The A&S system reverses and eliminates this by setting the ejectors automatically, every time, and using this rod to selectively disengage the ejector when the individual hammer has not fallen. So, the hammer never strikes any part of the ejector system.

The A&S ejector design also eliminates the extensions of the ejectors hooks which typically lay underneath the top rear portion of the forearm wood. Elimination of these hooks prevents accidental damage or cracking of the forearm during disassembly.
 

General

Each gun is built to the customers specifications: stock configuration, barrel length and weight, and total weight. However, A&S carefully balances these factors to produce the perfect balance so the gun feels and swings without any sensation of weight.

By controlling the barrel taper and barrel wall thickness near the muzzel A&S is able to move the polar moment of inertia of the barrel forward towards the muzzel while holding the total barrel weight specification so as to preserve overall weight and balance requirements of the gun. By shifting the barrel balance point forward, for a given barrel weight, the barrel stability, particularly on long targets, is improved and swing becomes smoother, yet the gun retains its liveliness.
