stribog spa1 trip v2

skunkwerks 637.2KiB Released December 22, 2025, 11:33 AM

The final (prototype) slip trip for the Stribog SP9A1 PCC.
You must trim the left side and the bottom of your buffer to clear this slip trip.
This was designed to work with the A3 Industries scorpion lower and last round bolt hold open lever they supply with the lower.
If you are going to reuse the original lower, you will need to trim your last round bolt hold open lever.
Lastly, you must do the same 24mm slot in the upper receiver that is used on the SP9A3 models.
