- $329
In short: The SAG S20120 adapts compatible AK and Saiga platforms with a 5.5 mm rear trunnion for a Bushmaster ACR-pattern stock and cheekpiece.
Compatibility checkpoint
- Confirmed platforms: AK and Saiga.
- Required rear interface: 5.5 mm rear trunnion.
- Compatible stock system: Bushmaster ACR-pattern stock and cheekpiece.
- Important limitation: the stock folds only partially, and the installed configuration blocks use of the original mechanical sights.
Selection rule: Confirm the 5.5 mm rear-trunnion interface before ordering; a similar platform name does not confirm the required rear geometry.
Purpose
