I went to a few shops but it seems since the gun is so old i am having problems finding this bolt does anyone know Where can i find a stock or aftermarket dm7 bolt new or used?
You can get a BW one for around 100 like Prem mentioned. You could also search for a used stock fuse bolt. DM6, 7, and 8 all take the same bolt if I'm not mistaken.
call Dye and talk to a tech and they sometimes have used botls that they will sell you. That is how I got my Ultralite frame for my DM4. Call Dye and pray for luck!
