Strike Systems Ø25.4 mm Low-Profile Rings for 21 mm Rail

A pair of low-profile rings for airsoft, designed to mount optics and red dots with a 25.4 mm body on Picatinny and Weaver rails of 21 mm. The clearance between the optic and the rail is just 6 mm, keeping the optical centreline as close as possible to the replica's bore axis.

Such a low profile drops the sight picture and brings the line of sight closer to the barrel, reducing the hold-over angle when acquiring a target. The result is a more natural head position and faster alignment, particularly in the close-range dynamic shooting scenarios typical of airsoft. The trade-off is that with only 6 mm of clearance under the optic body there is no room for standard-height backup iron sights: anyone who wants to retain emergency iron sights must check compatibility before mounting.

Each ring is secured by 4 screws, providing an even grip around the optic body that distributes pressure across the full circumference and avoids deforming the tube. The package includes both rings, sufficient for a complete mounting.

Key points

• The 25.4 mm inner diameter is compatible with most compact airsoft scopes and tubular red dots
• The 6 mm clearance between rail and optic lowers the line of sight and promotes a more natural cheek weld
• Four screws per ring distribute pressure evenly, reducing the risk of slippage under repeated recoil
• The 21 mm rail specification ensures compatibility with the standard Picatinny and Weaver rails found on most replicas
• The low profile rules out the use of standard-height backup iron sights: assess this before installation

In the box

• 2 rings (complete pair)
• 8 mounting screws (4 per ring)
