the Interdynamics MKS assault rifle (top, with buttstock unfolded) and MKS carbine (bottom, with buttstock folded)
  MKS rifle MKS carbine Caliber 5.56x45 mm Action Gas operated, rotating bolt Overall length (butt open / folded) 868 / 634 mm 751 / 517 mm Barrel length 467 mm 350 mm Weight 2,75 kg 2,36 kg Rate of fire 750 - 1100 rounds per minute Magazine capacity 30 rounds The Interdynamics AB company of Sweden attempted to enter an assault rifle market with its MKS rifle in mid-1970s. The Interdynamics MKS assault rifle was more or less conventional in respect to materials and technologies, but layout was not conventional, with box magazine serving as a pistol grip. This layout resulted in shorter overall length when compared to conventional rifles with the same barrel lengths, but seriously compromised ergonomics. Because the standard 5.56mm magazine is significantly deeper 9front to back) than a typical pistol grip, the firing hand's hold and a trigger reach were far from being comfortable. The MKS rifles never were made in any quantities and deserved its place in firearm history more as a curiosity than anything else.

T86 carbine
  T65 rifle T86 carbine Caliber 5,56x45 mm NATO Overall length 990 mm 880 / 800 mm Barrel length 508 mm 375 mm Weight 3,17 kg empty ? Rate of fire 700-800 rounds per minute ? Magazine capacity 20 or 30 rounds T65 assault rifle was developed at Taiwan state arsenal to replace obsolete 7,62mm M14 rifles of US origin. The T65 rifle closely resembles US-made M16A1 rifle and is probably made on US-supplied machinery, although the Taiwanese rifle has some differences in design and appearance. Reports on original T65 rifle suggested that it performed not satisfactory, so it was improved and became T65K2 (also sometimes referred to as T68). Later on, a T86 carbine was developed - it is very similar externally to US-made M4 carbine although it has piston-type gas action of T65. The last weapon in this line-up is T91 carbine, which can be described as T86 with carrying handle replaced by Picatinny-type accessory rail.
