The NATO Stock Number (NSN) is currently used by the international military alliance as a way to identify all the “standardized material items of supply” – and it has become so widely adopted that many U.S. partners that aren’t actually part of NATO still use it. In other words, NSN is something a certain politician might describe as a “big deal.”
This month, Sig Sauer announced its full ROMEO2 kit has been assigned NSN: 240-01-717-4679 and officially placed on the MHS Additional Authorized List (AAL). This distinguished designation is part of the continued modernization efforts of the Modular Handgun System (MHS) Program, and the adoption of Sig Sauer accessories designed and engineered to enhance the M17 and M18 platforms – the military designations of the full-size and compact versions, respectively, of the P320 semi-automatic pistol.
The ROMEO2 Hit the Bull’s Eye
For inclusion on the MHS Additional Authorized List (AAL), the U.S. Army evaluated numerous pistol red dot sights, from multiple manufacturers, through vigorous environmental and performance evaluations. The ROMEO2 and the previously awarded ROMEO-M17 (NSN: 1240-01-713-9795) each achieved successful selection – and that could streamline the procurement process for all NATO members and partner countries as the sights have been identified as standardized material.
The ROMEO2 is a Red Dot Reflex Sight featuring a molded glass aspheric lens with high-performance coatings for superior light transmittance and zero distortion. It is available with a 3 MOA, 6 MOA, or Circle/Dot reticle, and offers D.A.R.C. (Dark Adaptive Reticles and Coatings) technology to provide ideal reticle brightness and target clarity during the day and while using a Gen3+ night vision device. Its MOTAC (motion-activated illumination system) automatically turns the optic off when not in use, and automatically turns it back on when it detects motion, enabling up to 25,000 hours of battery life, while the MAGNETAC (Magnetic Activation) automatically turns the optic off when holstered in a compatible holster, and on when drawn.
The Sig Sauer ROMEO2 is crafted with 7075 aluminum housing, while it is offered with two (2) steel shrouds for three (3) different optic configurations, including fully enclosed and sealed. Additionally, a spring-loaded side battery tray with push-button release allows a battery change without the need to remove the optic from the firearm.
The approved MHS AAL ROMEO2 kit further includes Berry-compliant wrenches, an X-RAY3 green suppressor-height front night sight to co-witness with the integrated rear sight on the ROMEO2 housing, and a plug to fill the hole in the rear of the MHS slide when the sight plate is removed.
