Manroy USA

Firearms, Spares and Accessories Built to Tough Military Standards

Manroy USA, LLC, is a US-based company.

We recently completed the acquisition of all Sabre Defense Inc (SDI) assets and the inclusion of those capabilities in March 2011. For all business in the US we operate as Manroy Defense Systems (MDS).

The company was established principally for the manufacture and supply of weapons, weapon spares, mounts, and weapon accessories to the US Department of Defense. We are now a prime contractor to PM Soldier Weapons, ARDEC, TACOM and DLA. We are also an approved source of supply to General Dynamics, BAE Systems, and Alliant Techsystems for manufacture of precision machined and fabricated parts and/or assemblies.

Recent Manroy USA contracts include:

  • M16A3 and A4 rifle

Manroy Mk43 Mod 0 electronic boresight system (EBS)

Our Mk43 Mod 0 EBS is a unique boresight designed to be operated by a single operator more quickly than existing solutions, while delivering a dramatic increase in performance. Currently in use by both the Navy and Air Force, the system was designed to operate throughout a wide range of weapons and weapon systems. Designed for optically enhanced turrets, remote weapon stations and other mounted optics; timely procedures ensure repeatable accuracy.

At Manroy we have moved rapidly throughout our brief history to best position ourselves to support fully the demands of our government customers. We continue our growth by improving on our new 130,000 square foot facility, whether through additional range facilities, more machining capacity, or development of new or improved products.
