INNOmount Picatinny rail for Howa 1500 SA, 20MOA

About Picatinny Rail

The Picatinny rail system is meticulously designed with slots spaced at exact intervals of 5.23 mm, ensuring both consistent and versatile use throughout its length. This precision allows for straightforward mounting and guarantees universal compatibility, ensuring that scopr mounts tailored for a Picatinny rail will seamlessly fit, irrespective of the manufacturer or date of production. Favored for its cost-effectiveness, robustness, and dependability, the Picatinny rail is increasingly popular among experts and military users, becoming the top choice in the scope mounts market in recent years.

The Picatinny framework marks a notable enhancement over the traditional Weaver standard. Unlike the Weaver system, which has only a limited number of slots, the Picatinny rail boasts continuous slots across its entirety, providing enhanced flexibility for positioning devices at any desired point. Additionally, the slots on a Weaver rail are slimmer, measuring 3.8 mm, which permits scope mounts made for Weaver rails to be used on a Picatinny rail. However, due to differences in the width of the recoil stoppers, scope mounts specifically designed for the Picatinny rail cannot be accommodated on Weaver rails. This level of compatibility and adaptability makes the Picatinny rail a superior option for a variety of mounting needs.

About the Howa

Howa Machinery Ltd., known as Howa, is a versatile Japanese manufacturing company established in 1907. Initially focusing on looms, Howa diversified into weapons production in 1936, manufacturing items like rifles and machine parts during the war. After a post-war shift back to looms, they resumed arms production during the Korean War, producing rifles like the Howa 1500, introduced in 1979 as a budget precision rifle. 

About the Howa 1500 SA 

The Howa 1500 SA is a centerfire push-feed bolt-action rifle. Introduced in 1979, it features a Mauser-type action with a cold hammer-forged barrel and a forged-steel receiver. The Howa 1500 SA is equipped with a basic two-stage trigger and a three-position safety mechanism. This model comes with four tapped holes in the receiver, making it suitable for straightforward scope mounting. It also offers a choice of a fixed or detachable box magazine, accommodating 3-5 rounds depending on the configuration​​.

Calibres

Howa 1500 SA is chambered for the following calibers:

• .204 Ruger
• .223 Rem.
• .22-250 Rem.
• .308 Win.

Inclination

20 MOA inclination is only needed when the scope runs out of elevation. For example, when shooting at the range of 100 m, shooter gains 58.2 cm / 100 m of additional elevation range with a 20 MOA mount. This is approximately 5.8 Mrad of elevation. To make things even clearer – if the target was placed at 100 m, the scope with 20 MOA inclined rail would aim to the center of the target while the rifle’s barrel would aim 58 cm higher than the scope. This gives the shooter extra elevation needed for long range shooting. If you plan to shoot on distances longer than 600 meters, 20 MOA is most common. There is no negative effect of the inclined Picatinny rail in the mounting setup if you only shoot on shorter distances. The same goes also the other way around, since if you don’t shoot on extreme distances then Picatinny rail with inclination is not needed.

This rail can also be mounted on:

Usually, a Picatinny rail can be mounted on multiple different rifles if they share the same mounting surface, which we commonly refer to as the mounting standard. The INNOmount Picatinny rail for Howa 1500 SA, 20MOA can be mounted on the following rifles, which share the same mounting standard:

• BRNO Scandinavian
• CZ 550 Scandinavia
• Smith & Wesson 1500 SA
• Weatherby Vanguard SA

Mounting Instructions

Clean the rifle's receiver thoroughly with a cleaning fluid, such as acetone, to remove all stains, grease, and oil. Once the surface is clean and dry, verify that the screws fit both the rail and the receiver holes. Before mounting the rail, apply a minimal amount of thread-locking fluid (278 or 648) to the screws, avoiding any contact with the mounting holes. Carefully clean any excess fluid around the rail using the cleaning fluid. Using a torque driver, tighten the screws to the appropriate torque (up to 3 Nm/26.5 in-lbs). If you require any mounting tools, you can find them on our Rifle Scope Mounting Tools page.
