TSM200 Tech Sights Aperture Sight for Marlin 60 and 795

Why Choose the Tech-SIGHTS TSM200 Sight?

The Tech-SIGHTS TSM200 is designed for shooters who want a more capable iron-sight system without replacing their rifle or permanently modifying the receiver. By moving the rear aperture closer to the shooter's eye, the TSM200 increases the sight radius by approximately 6 inches compared with the original sight arrangement. The result is a cleaner sight picture and a more consistent aiming reference for target shooting, plinking, small-game hunting, and marksmanship practice.

The TSM200 combines a receiver-mounted rear aperture with a traditional GI-style front sight post. The shooter's eye naturally centers the front post within the rear aperture, making the sight picture quick to acquire while retaining the simplicity of traditional iron sights. The rear sight provides both windage and elevation adjustment with positive detent clicks, allowing the rifle to be precisely zeroed without relying exclusively on front-sight adjustments.

Compatible Rifles

The Tech-SIGHTS TSM200 is designed to fit a variety of popular .22 rimfire rifles and provides a practical replacement-sight solution for several models. Compatible firearms include:

• Marlin Model 60 – Marlin 60 replacement sights and aperture sight upgrade
• Marlin Model 795 – Marlin 795 replacement sights and peep sight upgrade
• Rossi RS22 – Rossi RS22 replacement sights and adjustable aperture sight
• Rossi Rio Bravo lever action – replacement rear sight and aperture sight upgrade
• Rossi Gallery pump action rimfire rifle with synthetic stock – replacement sights and aperture sight upgrade

Always verify your specific rifle configuration before ordering, particularly if the firearm has aftermarket components or modifications that could affect sight installation.

Adjustable Windage and Elevation

Unlike a basic fixed aperture sight, the TSM200 allows adjustments at the rear sight for both windage and elevation. Detent adjustments provide positive positioning when zeroing the rifle, making it easier to establish a repeatable zero and compensate for changes in ammunition, distance, or shooting conditions.

The windage adjustment can generally be made by hand, while elevation can be adjusted using a pointed object. Tech-SIGHTS also offers the TS211 spanner wrench as an accessory for shooters who want a dedicated tool for elevation adjustments.

Extended Sight Radius

The TSM200 moves the rear sight from its traditional forward position to the receiver, increasing the distance between the front and rear sights by approximately 6 inches. A longer sight radius reduces the effect of small alignment errors and gives the shooter a more precise reference when aligning the rifle.

This design is particularly useful for shooters who prefer iron sights but want a sight picture that is easier to align consistently than a conventional open rear sight. The aperture also allows the eye to naturally center the front post, making the system fast to acquire while maintaining a familiar rifle sight picture.

No Drilling or Tapping Required

The TSM200 is designed as a straightforward replacement-sight upgrade without requiring drilling or tapping of the rifle. This makes it an attractive option for owners of Marlin and Rossi rimfire rifles who want to improve their factory iron sights while avoiding permanent receiver modifications.

The installation replaces the existing sight arrangement with the Tech-SIGHTS front and rear components. Once installed and properly zeroed, the receiver-mounted rear aperture provides a durable sighting system suitable for regular range use, plinking, hunting, and marksmanship training.

Ideal Uses for the TSM200

• Replacing factory sights on a Marlin 60 or Marlin 795
• Upgrading Rossi RS22 sights
• Upgrading a Rossi Rio Bravo lever-action rimfire
• Replacing sights on a compatible Rossi Gallery pump-action rimfire rifle
• Target shooting and range practice
• Plinking with .22 LR rifles
• Small-game hunting
• Appleseed and marksmanship training
• Shooters who prefer aperture sights over scopes or traditional open sights

What Is Included?

The Tech-SIGHTS TSM200 includes the adjustable rear aperture sight and matching front sight required to create the complete sight system. The standard aperture uses a .062-inch opening, and optional aperture sizes are available separately for shooters who want to customize the sight picture for different applications.

TSM200 Replacement Sight Benefits

For shooters searching for Marlin 60 replacement sights, Marlin 795 replacement sights, Rossi RS22 replacement sights, or Rossi Rio Bravo replacement sights, the TSM200 provides more than a simple replacement for a damaged factory sight. Its receiver-mounted aperture design extends the sight radius, while adjustable windage and elevation provide greater control when establishing a precise zero.

The combination of a longer sight radius, adjustable rear sight, GI-style sight picture, and no-drill installation makes the TSM200 a practical way to upgrade the iron sights on compatible Marlin and Rossi rimfire rifles while retaining the simple, lightweight characteristics that make these rifles popular.
