A3 scorpion lower is a direct swap for stribog sp9a3 and allows it to use scorpion mags, ar triggers, pistol grips, and safety selectors.


Installed then replaced with a aluminum lower.

Missing take down pins but will throw in a out of spec a3 xeno pistol grip. Came from a3tactical and wouldnt fit, haven't tried using a heat gun or diesel but it'll probably work to fit.
