Accuracy International AT308

The History of Accuracy International

Accuracy International was founded in the UK in 1978 by Malcolm Cooper, a British Olympic medalist in shooting, and Sarah Cooper, his wife. The company was established with the aim of creating a high-precision rifle that would meet the needs of competitive target shooters and military snipers alike. In 1982, they introduced their first rifle, the AI Arctic Warfare rifle. The rifle's accuracy and reliability made it a favorite of military and law enforcement agencies around the world. In the 1980s and 1990s, AI continued to refine and expand its product line, developing new models like the AW50 and the AWM (Arctic Warfare Magnum). These rifles were designed to meet the needs of different users, from military snipers to police SWAT teams.

In the early 2000s, AI secured a contract to supply rifles to the British Armed Forces, cementing its reputation as a supplier of high-quality military equipment. The company's rifles were used by British forces in Iraq and Afghanistan, where they earned a reputation for their accuracy and reliability. AI continued to expand its product line, offering rifles for civilian use, as well as law enforcement and military applications. Today, AI is known for its commitment to precision, quality, and reliability, and its rifles are widely used by military and law enforcement agencies around the world.

The company has always been focused on developing new technologies and refining existing ones to create rifles that are even more accurate, reliable, and durable. This commitment to innovation has led to the development of advanced features like detachable magazines, adjustable stocks, and precision triggers. AI has also developed proprietary technologies, such as the Quickloc barrel system, which allows users to quickly change barrels on their rifles. The company remains a small, independent company that is owned and operated by the Cooper family, who continue to oversee every aspect of the company's operations.

Accuracy International AT308 Rifle Review

The Accuracy International AT308 is a bolt-action precision rifle designed for the short-action .308 Winchester cartridge and a successor of the AW308 model. The rifle is equipped with a proofed steel push-feed action that is bonded and bolted to an aluminum chassis. The action features AI's Quickloc - quick release barrel system, which makes it easy to change the barrel if necessary.

The rifle's 20 MOA STANAG 4694 / Mil Std 1913 receiver and forend rail provide the necessary versatility to mount various accessories such as scopes, bipods, and other equipment. The AT308's bolt is a six-locking-lug, 60-degree opening angle design with AI's combat-proven leaf spring extractor. The rifle also includes a 3-position safety that is easy to operate and helps ensure safe handling in all conditions. The two-stage trigger is adjustable for trigger weight between 1500 and 2000 g (3.3 and 4.4 lbs), which allows for precise control of the rifle.

The rifle features a detachable 10-round double-stack magazine. Additionally, it can be loaded through the ejection port. The AT308 weighs 5800g when unloaded and equipped with a 610 mm (24 inch) barrel, which is optimal for long-range accuracy.

What are the main benefits of mounting a red dot sight on a shotgun?

The first and biggest benefit is the faster and easier aiming possibility since your eyes do not need to focus on bead sights or open sights on the rifle, and on the same time also on the target. This is especially noticeable among older shooters, which do not see so good anymore like the younger ones. Because aiming with a red dot sight is much faster, it is the perfect solution for driven hunts, where the hunter does not have much time to place the perfect shot.

A mounted red dot sight on a shotgun is also very handy for shooters which have opposite dominance of the eyes and arms – right hand and left eye for example.

As most of the hunters know, aiming over the rib with bead sights isn’t very accurate since different shotguns shoot differently.

  • This is especially noticeable when shooting slugs.
  • With a red dot, the shotgun can be shot very accurately and the red dot can be perfectly zeroed.

Why this aren’t picatinny rails that are going straight to the rifle body?

Shotguns with a pre-mounted Picatinny rail are mostly tactical shotguns, which are used by the police and military. But because the Picatinny rails are very popular for mounting optics and other accessories, many semi-auto hunting shotguns have the holes for mounting a rail already prepared.

In this category, we listed mounts that can be mounted

  • directly on the rib of the shotgun or
  • between the stock and the action of the rifle.

To do so, the rib on the rifle has to be ventilated. A ventilated rib is most common on "over and under" shotgun rifles, and is very rare on "side by side" shotgun rifles.

It is worth to mention that all mounts that come on the rib of a shotgun have to be pushed towards the muzzle to ensure a perfect fit with no movement during shooting sessions.

Picatinny rails for mounting on the "rib" of a shotgun

A Picatinny rail that can be mounted on the rib of a shotgun has one major benefit – it can be mounted on the entire length of the rib, so every user can adjust the eye-relief to his favorite position.

When a Picatinny rail is mounted, also the selection of the red dot sights increases. Almost all sights on the market feature a mounting solution for a Picatinny rail, so the user can easier decide what to mount. It is, whatsoever, worth mentioning that these Picatinny rails are not designed to be used with combination with a traditional rifle scope since the additional weight could damage the rib on the shotgun.

Because of the different shapes of the ribs on the shotguns, the manufacturers produce these Picatinny rails in different dimensions for each individual rifle. The most known manufacturer of such Picatinny rails is Recknagel, which has the widest selection on the market.

Docter Sight mounts for mounting on the "rib" of a shotgun

The "Docter Sight" mounting platform is the most common platform on red dot sights on the market. There are many companies that use this platform as their preferred one, because in most cases it is the lowest mounting solution.

The red dot sights that use this mounting platform are from design up very low, which is perfect for mounting on a shotgun since the aiming point does not travel too much higher, and the user still has to aim over the rib as before.

Typically, these mounts can be mounted on many types of shotgun ribs, so they are not designed for one specific rib on one specific shotgun.

Aimpoint Micro mounts for mounting on the "rib" of a shotgun

Aimpoint Micro mounts are practically the same as the Docter Sight mounts, just that they have an Aimpoint Micro profile instead of a Docter Sight profile. Today, this footprint is also widely used for other red dots on the market.

From the combination of these mounts and Aimpoint Micro red dots, the idea for the Micro S-1 was born.

Docter Sight mounts for mounting between the stock and the action of the rifle

To mount a red dot sight between the stock and the action on a shotgun was an idea from the American company Burris, which is owned by the Beretta group. In this group are also many companies which produce shotgun rifles, such as Benelli, Franchi, Stoeger, and so on.

On these mounts not only the Docter Sights can be mounted, but all red dot sights on the market that have the same footprint.

The main benefit of such a mount is the distance to the eye – because it is very close, the user quickly finds the red dot in his field of view. Whatsoever, many users don’t like this solution because the aesthetics of the rifle changes.

Red dot sights that can be mounted directly on the "rib" of a shotgun

The first red dot sight on the market with such a solution was from the Swedish company Redring. It can be mounted on any rib width ranging from 5 to 11.5 mm, on Over/Under, and Semi-automatic shotguns.

Because such sights are gaining on popularity, more and more companies design their own red dot sights that can be mounted directly on the rib of the shotgun.
