Vltor A5 system consists of the longer RE15 or
RE10/A5SR, the Vltor A5 spring (rifle length spring), and longer A5
buffers. None of A5 components are compatible with standard AR15/M16
carbine receiver extensions, springs, and buffers.
The RE-A5 Receiver Extension is a seven position receiver extension
designed to work with the VLTOR A5 system. This receiver extension is
slightly longer than the traditional M4 receiver extension and is
designed to work with Mil-Spec dimensioned M4/AR-15 type collapsible
stocks.
- Seven position receiver extension made from impact extruded 7075 T6 aluminum
- Hard coat anodized
- Positions are numbered and are visible through the witness hole on most stocks
- Snag-free sliding of the buttstock
