## Summary

The Civil Nuclear Police Authority and Civil Nuclear Constabulary are buying backup iron sights for officers’ GR115 carbines. The sights will work alongside the Constabulary’s chosen holographic primary sight and provide a dependable alternative if that sight fails, is damaged or unavailable, helping maintain officers’ operational capability. This is a supply contract for firearm sighting equipment and associated parts. Delivery is to the United Kingdom. The requirement is for backup sights rather than the primary holographic sight system.

The buyer invited offers through an open competition. The contract is divided into one lot and was presented as suitable for small and medium-sized businesses and voluntary, community and social enterprises. Enquiries were due by 23 October 2026 at 11:00, and bids by 2 November 2026 at 12:00. The contract period is scheduled to run from 23 November 2026 to 23 November 2031, with options described as two periods of 12 months, for up to two additional years. The estimated value is £100,000 excluding VAT (£120,000 including VAT). Award is based on quality weighted at 70% and price at 30%.

This requirement may suit suppliers able to provide backup iron sights compatible with GR115 carbines and intended to operate alongside a holographic primary sight. The sights need to offer a reliable secondary aiming capability if the primary system cannot be used, so relevant product compatibility and dependable performance are central to the requirement. The buyer identifies the opportunity as suitable for SMEs, as well as voluntary, community and social enterprises. Suppliers in the firearms, defence or specialist sighting-equipment market may find the product scope relevant. The requirement is for goods, rather than installation or other services; the notice describes no particular accreditation, technical standard, delivery quantity or prior experience requirement.

## Notice

The CNC requires Backup Iron Sights (BUS) to provide a reliable secondary sighting capability for its GR115 carbines. The BUS will be used alongside the CNC's chosen primary sighting system, a holographic sight, and must enable officers to retain an effective sighting capability should the primary sight fail, become damaged or otherwise be unavailable. This requirement supports operational resilience by providing a dependable and readily accessible alternative sighting option.
