3DP Tac Sol Stribog SP9A3 FRT Trip Sled

The 3DP Tac Sol Stribog SP9A3 FRT Trip Sled is the budget trip solution for an FRT or Super Safety build on the roller-delayed SP9A3. Printed in carbon-reinforced PET-CF, the sled acts as the interface between the moving Stribog bolt and the trigger's reset lever. Without it the forced reset timing is inconsistent and the trigger will not reset correctly; the flat Stribog bolt cannot trip an AR-style reset lever on its own.

This is a fit-it-yourself part, not a service. It requires an FRT-compatible aftermarket lower, with Lingle recommended, plus owner-performed upper clearance and buffer fitting. 3DP sells it as-is with no install support, so it suits builders comfortable doing their own gunsmithing. For those who would rather ship the gun out, the Skunkwerks steel trip conversion is the turnkey equivalent at a higher price.

3DP makes the sled in three fitments: SP9A1, SP9A3/SP9A3S, and SP10A3/SP45A3. The A3 version here matches the roller-delayed 9mm host most owners run an FRT on, since the delayed action smooths the impulse and slows the cyclic rate into a more controllable range.
