I don't have much hope but I have searched and searched and figured it wouldn't hurt to try here.
I don't know how he did it, but my son lost the complete bolt out of his Remington Mod 788 .243. If can help me in any way I would really appreciate it.
Thanks
Dunno if you ever found one - but you might try Don's on the frontage road of 410 by Fredericksburg, or The Powderhorn over between Hwy 90 and Marbach (inside the loop).
