Howa 1500 S

About the Howa

Howa Machinery, Ltd. (shortened Howa) is a Japanese manufacturing company that produces a wide range of products, from machine tools and sweepers to doors and windows, but it is internationally known for their production of civilian and military weapons. Originally named Toyoda Loom Works, the company was established in 1907 by the famous Japanese inventor Sakichi Toyoda who wanted to domestically produce looms (machines for weaving cloth), which he invented because most of these kinds of machines were imported back then. Twenty-five years later the company accepted its first order from the Japanese army and started producing weapons, their first product being a hand grenade. In 1936, they then started producing cannonballs, airplane parts and rifles. During the war, they manufactured Type 99 Arisaka Rifle, machine guns, artillery and infantry-gun parts.

After the war, they went back to only manufacturing looms because arms production was at first prohibited in post-war Japan. This all changed with the outbreak of the Korean war when the weapons restrictions were amended and the USA contracted them to produce a copy of M1 Garand and M1 Carbine for the Japanese Self Defense Forces. Howa has also manufactured many products and components for other arms companies, like Weatherby, Mossberg and Smith & Wesson. They also started producing sporting arms, entering the US hunting rifle market and building Japan’s first tunnel target shooting range. In 1960, they produced the Model 300 hunting rifle which was the first mass-produced hunting rifle in Japan. They achieved great popularity with their Howa 1500 bolt-action rifle which they introduced in 1979 and which has since been named one of the best budget precision rifles. The Howa 1500 action is often used by other brands and sold under different names — on such example is Weatherby Vanguard which is essentially a Howa 1500 rifle with a different stock.

Howa 1500 S Rifle Review

Howa 1500 S (also known as Howa M1500) is a centerfire push-feed bolt-action rifle introduced in 1979 as a budget precision rifle. It consists of a Mauser-type action, a cold hammer forged barrel and a forged-steel receiver. The bolt has two locking lugs, an M16-style ejector and extractor. Howa 1500 rifles have a basic two-stage trigger, although models released after 2011 feature a new two-stage trigger system called HACT (Howa Actuator Controlled Trigger). The safety is a three-position catch that locks the trigger and the bolt. The internal magazine can hold 3–5 rounds, loaded through the action, but some models come with a removable box magazine which can hold up to 5 or 10 rounds. Howa 1500 comes in three action lengths: mini, short, and long.

Not to be confused with Howa 1500 SA, this is a much rarer version with a different mounting surface (R47.5 radius instead of R60)

This rifle has four holes on the receiver for mounting purposes.

Which rifles have interchangeable mounts

Two-piece mounts

For two-piece mounts to be interchangeable the mounting surfaces of the rifles must match in every dimension except the B dimension which can vary. This is because the distance between the two pieces of the mount is not fixed. Rifles that have two-piece mounts interchangeable with Howa 1500 S are the following:

none

One-piece mounts

The necessary condition for rifles to have one-piece mounts interchangeable is that the mounting surfaces of these rifles match in every dimension. Rifles that have one-piece mounts interchangeable with Howa 1500 S are the following:

none

Our recommendations for mounts

Fixed mounts

None are available.

Detachable repeatable mounts

The EAW company is the only company that produces detachable repeatable mounts for Howa 1500 S. A great fit for the rifle would be EAW pivot mount.

Picatinny rails

This is the only Picatinny rail on offer.

Help us build our riflescope mounts database

If you happen to own this or any other rifle, we would appreciate it if you could help us expand our database by sending us some photos of the rifle receiver (the bare mounting surface of the rifle without the mounts installed). For your help, our company offers a fair return in terms of practical rewards.

Introduction

In recent years we can observe that a trend of Picatinny rail has become widespread and global. It is driven by the NATO standardized rails, more commonly known as the Picatinny rail standard. Picatinny rail being the New Jersey Arsenal that developed it in 1995.

These mounting options are revolutionary. The biggest and best advantage being that the Picatinny rail can be used its entire length and not bordered to a few pre-designed slots like for example the Weaver rail standard was before.

The other main advantage is the ease of use and interchangeability. If a product is meant for a Picatinny rail design it will fit all Picatinny-rails, no matter the manufacturer or date of production.

Picatinny/Weaver Rail

Picatinny Rail and Weaver rail profile

Design

The Picatinny rail is almost exclusively crafted from a single piece of metal (in some cases aluminum). In this manner, the axis of the Picatinny rail is perfectly straight and aligned with the axis of the firearm. Therefore the rifle scope which is mounted onto this kind of configuration is certainly aligned with the rifle / gun and the trajectory of the ammunition.

Weaver rail design on the other hand is usually manufactured in two separate pieces, greatly increasing the possibilities for the axis to be crooked, overlapping, and out of line.

It is always harder to align two separate pieces to a third line than it is to align one piece to another. In this way, the lapping of two mounting rings on a single-piece Picatinny rail is no longer required.

The single-piece rail will assure that both rings are perfectly aligned to each other and that no unwished stress is transferred to the riflescope.

Picatinny compare to Weaver Rail

The Picatinny rail itself is an evolutionary step forward from the older Weaver rail. The main difference between Picatinny rail and Weaver rail is the spacing of the slots. Picatinny rail design has them evenly placed exactly 5.23 mm from one slot to the other, 3 mm deep. For this reason, the mounting options are repeatable and the same as other firearms using the Picatinny rail standard.

Interchangeability was a major driving force in the development of the new standard as different NATO armies need to be compatible with each other.

Weaver rail has 3.8mm wide slots and these slots can be placed anywhere on the Weaver rail and in any number that the producer wished.

Advantages of Picatinny design

A big advantage for using the Picatinny rail design is the ever-present recoil stop. Furthermore, the manufacturing of the rail is not very technically demanding and can be done without the use of state-of-the-art machines which greatly reduces the cost of the finished product, making it very affordable.

The Picatinny rail is easy to mount and usually, this type of configuration does not transfer negative stresses and forces from the fired weapon to the rifle scope.

In addition, the Picatinny rail with its very long useable surface works well for mounting longer rifle scopes or to achieve optimum eye relief.

The durability and toughness are other big pluses for this solution.

Manufacturers of Popular Models

A majority of the Picatinny rings are fixed, but a number of best rated European manufacturers (EAW, MAK,..) have, in recent years, put a lot of effort into the development of detachable ring with100% repeatability, with which it becomes easy to remove the scope from the weapon without the use of tools.

No re-zeroing is needed with such mount options, but these models tend to be expensive.

Weaver and Picatinny Rings

Picatinny rail and weaver rail share one more thing. It is possible to use the Weaver ring and the Picatinny ring on the Picatinny-rails, but it is usually impossible to use the Picatinny ring on the Weaver base. The reason being the above-mentioned positioning and spacing of the slots.

Picatinny mounts have a 5mm recoil stop that goes into the rail slot and since
Weaver rail only has 3.8mm wide slots such rings do not fit on Weaver rails.

Due to this reason, the Picatinny-rails are popular and prevailing on the market in recent years and eventually, these options will completely oust the Weaver rail from the market.
