AK-BUILDER MODULAR STOCK TRUNNION, A4-41

AK-Builder Modular Stock Trunnion

$55.00

AK-Builder Modular Stock Trunnion — for 1.0 mm Receivers

This rear trunnion lets you mount the ACE Modular stock system without cutting the tang on an original trunnion. Designed for 1.0 mm stamped AK receivers.

Details

  • Trunnion has rivet holes pre-drilled.

  • Intended for a receiver without existing rear trunnion holes. If your receiver already has holes, they’re in a different location than an original fixed-stock pattern and would need to be welded up and re-drilled to use this trunnion.

  • Stock mounting holes are tapped 10-32.
