About
What it is, and why it matters
The OTs-126 is a semi-automatic civilian carbine developed by Russia's TsKIB SOO (the Central Design and Research Bureau of Sporting and Hunting Arms, a Tula-based design house associated with KBP). Unveiled at the ARMY-2018 International Military-Technical Forum, it is a civilian-legal derivative of the KBP PP-2000 submachine gun chambered in 9x19mm. To comply with Russian civilian firearm law it is restricted to semi-automatic fire, fitted with a reduced 10-round magazine and a lengthened barrel to meet hunting-carbine dimensional requirements. TsKIB SOO designed a new upper receiver covered in Picatinny rail and made it compatible with AR-15-pattern stocks.
The OTs-126 is what happens when a Russian special-forces submachine gun goes hunting: TsKIB SOO took the compact PP-2000 PDW, stretched its barrel, throttled it to semi-auto, and bolted on AR-15-friendly rails to make it legal for civilian buyers.
Specifications are sparse: at unveiling the weapon was still undergoing legal certification for the Russian civilian market, and detailed dimensions, weight, and ballistic figures were not published. Most physical specs are inferred-unknown and left null.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
