Attaching a folding stock adapter will depend on the chassis systems interface and buttstock. Depending on the inlet, we design our chassis systems that have Fixed or Carbine interfaces.
For Fixed interfaces, you will use "Fixed to Fixed" or "Fixed to Carbine."
For Carbine interfaces, you will use "Carbine to Carbine" or "Carbine to Fixed."
The ACC. ESS, ACC Premier Gen 2, ACC Elite and the LSS Gen3 use a proprietary XTN interface. Both chassis systems can be ordered individually, piecing them together with the SRS-XF buttstock.
*Please note; that if you buy the ACC or ESS kit it will have a non-folding buttstock, an adapter can not be added; it is a whole new buttstock that would be required
*Please note; the SRS-XF does not fold flat with the ACC Elite, ACC Premier Gen2 or LSS Gen 3, we are working on a new design soon.
