Posted 27 Mar 2018 This bolt is in excellent condition with very little signs of wear. It looks to have been professionally drilled to lighten for increased cyclic rate. Please let me know if you have any questions or picture requests. $250.00 Delivered. Mesa, Arizona, United States Share this post Link to post Share on other sites
Posted 28 Mar 2018 (edited) For what it’s worth, looks like a Gun machines modification. They milled the bolt to lighten and removed the ears from the Blish lock to greatly increase speed. Ron Edited 28 Mar 2018 by ron_brock Share this post Link to post Share on other sites
