I have an original model 700 Etronix-X in 22-250. I bought it brand new 2003 and I have 1 box of ammo left. I guess it’s time to modify and try to put a standard trigger in it.
I found this video that a guy had one modified to work. I have no idea how much this might cost.
I thought those were bringing huge money for collectors a year or two ago? Might be worth a look to see what they’re bringing before you get to work on it.
