2230 saw the wide introduction of various new rifles designed to fire a new breed of caseless ammunition. The ammunition was designed with lower tech manufacturing in mind and delivered less flash for the same amount of punch as older types. The formula and manufacturing techniques were extensively licensed by Dynamit-Nobel to several independent colony worlds enabling them to build cheap and rugged weapons around it.
One such weapon was the SK21. Designed and built by Micasa AG based on the independent colony of New Ireland, the SK21 is representative of the myriad of versatile and inexpensive weapons distributed throughout human space. Standard accessory rails allow the attachment of advanced targeting systems and grenade launchers with the 7mm slug giving good range and penetration. Expect to see weapons like this in the hands of many colonial forces and some less wealthy mercenary or corporate units.
