This was custom made by John Thomas of Retro Gun Works. It's a Rock River Arms Entry Stock with extended buttpad. Comes with a carbine buffer and spring.
Mottled brown finish, and the receiver extension is retro gray.
This was a custom project for the pictured dissipator, which now has an A1 stock.
$85
