68 Carbine Pro-Line Feedneck Screws

01-25-2026, 11:30 AM

I recently acquired a .68 carbine and the pro-line feedneck/Ca Adapter is missing 3 out 4 screws. Looks similar to the screw that holds in the Ball retention, but none of the manuals actually list size information. Does anyone know off hand which screws I need to thanks in advance.

From the pictures they look a bit bigger than 4-40, I would guess 6-32?

And God turned to Gabriel and said: “I shall create a land called Canada of outstanding natural beauty, with majestic mountains soaring with eagles, sparkling lakes abundant with bass and trout, forests full of elk and moose, and rivers stocked with salmon. I shall make the land rich in oil so the inhabitants prosper and call them Canadians, and they shall be praised as the friendliest of all people.”

“But Lord,” asked Gabriel, “Is this not too generous to these Canadians?”

And God replied, “Just wait and see the neighbors I shall inflict upon them."
