About NiosI Firearms Development

Niosi Firearms development is a Federally licensed weapons sales and manufacturing business located at the Gabreski airport in Westhampton Beach.

Our principal business is sales to Law Enforcement and Governmental Agencies, however, in these uncertain times we are stocking civilian appropriate weapons and ammunition.

Long guns (rifles and shotguns), as well as sidearms for those licensed to acquire them (including Glock, Sig, S&W, Wilson Combat, Nighthawk Custom, Heckler and Koch, Ruger and FNH) are in stock, as well as our usual array of select fire Law Enforcement only weapons.

We provide gun smithing to convert your existing gun library to NY State SAFE Act compliance.

A full inventory of women’s and men’s First Tactical wear is on display.

As are adult, student, and child size discrete bullet proof backpacks. All of which are LvL IIIA protection, certified against all pistol calibers and shotgun gauges fired from as close as fifteen feet by the US National Institute of Justice and the UK Centre for Applied Science and Technology, the world leaders in armor rating standards.
