Stock adapter allows the attachment of AR15/M4 style buffer tube stocks and possesses a Picatinny rail mount.  The mount is on the same plane as the Troy Battlerail upper handguard and the North Eastern Arms (NEA) barrel clamp. This rail mount is also great for the attachment of BUIS rear sights when used in conjunction with the NEA barrel clamp.

The M4 stock is positioned higher with this adapter (higher than the original vz.58 wood impregnated buttstock and the original Czech side-folding stock) and is best used with an optic or BUIS. 

Manufactured by North Eastern Arms (NEA).  Material: 6061 Aluminum with a type III Hard Anodize.
