Accessory Top Rail | Short Saddle | 30mm | Tier One – rail adapter for precision mounting

Looking for a robust accessory rail for your rifle scope? This Tier One Accessory Top Rail provides a reliable Picatinny interface on top of your scope mount. It’s a compact solution for mounting additional accessories such as a red dot sight or rangefinder, without compromising the stability of your primary optics.

Our opinion on this rail adapter

This rail adapter stands out due to its minimalist yet thoughtful design. The 7075 T6 aluminium feels solid without adding unnecessary weight. The fit on the Monomount Short Saddle is tight – no play or wobble. Tier One’s decision to reduce production to just two CNC operations is clever: fewer steps mean less chance of dimensional deviations.

Technology and construction

The rail is milled from a block of 7075 T6 aluminium, known for its excellent strength-to-weight ratio. With a 30mm tube diameter, it fits perfectly on rifle scopes with a standard 30mm tube. The Picatinny top rail follows MIL-STD-1913 specifications, allowing virtually any compatible accessory to be mounted without issue.

The use of 5-axis CNC machines ensures tolerances of just a few hundredths of a millimetre. This means the rail fits precisely with no play – essential when you want to mount a secondary sight for airsoft or observation equipment. The black finish matches seamlessly with most optical setups.

Mounting and compatibility

This rail adapter is specifically designed for the Tier One Monomount Short Saddle. The Picatinny rail system is the standard for airsoft replicas and many PCP air rifles – offering secure attachment and broad compatibility.

Please note: this rail is an accessory for an existing scope mount. You will need the Monomount Short Saddle before you can use this top rail. Once installed, you have a full Picatinny interface for your additional optics.

Who is this rail adapter for?

This accessory rail is ideal for shooters who want to expand their rifle scope with extra functionality. Think of airsoft users who want to add a mini red dot sight for rapid target acquisition at short range, or sports shooters looking to mount a rangefinder. The robust construction also makes it suitable for use on air rifles with recoil – the rail remains stable during intensive use.
