Editing FN 303 (section)

==History==
The FN 303 is based on a project by the Monterey Bay Corporation designated the XM303. The development team consisted of designers and researchers from two [[paintball]] related design and manufacturing firms, including [[Airgun Designs]]. The prototype was named the UBTPS, Under Barrel Tactical Paintball System.<ref>{{cite web|url=http://www.gunfx.com/pages/nonlethal.html |title=U.T.P.B.S Under Barrel Tactical Paintball System |publisher=[[Gun F/X Tactical Development|Gun F/X]] |access-date=2012-06-30 |url-status=dead |archive-url=https://web.archive.org/web/20120218100850/http://www.gunfx.com/pages/nonlethal.html |archive-date=2012-02-18 }}</ref>

The design could be attached to an [[M16 rifle]]<ref>{{cite web |url=http://montereybaycorporation.com/Monterey%20Bay%20Corporation_files/303.html |title=Non-Lethal Weapon Measures of Effectiveness |publisher=Monterey Bay Corporation |url-status=dead |archive-url=https://web.archive.org/web/20091110112224/http://montereybaycorporation.com/Monterey%20Bay%20Corporation_files/303.html |archive-date=2009-11-10 }}</ref> and was conceived as a less-than-lethal weapon system coupled with a lethal weapon system, providing a wide range of response capabilities that were immediately available.  A stand-alone version was also developed.

The UBTPS also featured a rotating barrel magazine, allowing for a wide range of different projectiles to be available and selectable without the need to change magazines.

Also developed was a [[bismuth]]-weighted projectile to provide the necessary mass, allowing the UTPBS to achieve the engagement range requirements.
