front swivel stud - missing part

[truffle]

hello hello
A1 223 varmint---- the front swivel stud is missing the bbl channel 'nut'.
unlike older models having a rectangle steel washer and standard nut, my A1 has a different set-up. From the outside, it has a recessed hole but, the bbl channel has a 'mystery' and appears to use a unique stud as the through hole is very narrow.
what part(s) am I missing?

thank you in advance

What ever parts are missing will be next to impossible to find. Just get an Uncle Mike's front swivel stud with the round nut, drill the appropriate size countersunk hole for the nut on the inside of the stock & install it. If you don't have the right drill bits, any smith can install it in about 10 minutes.

Bloo, I had that same model & it came with swivel studs not the full sling loops. Full set of Uncle Mike's, which are exactly the same as Sako used, sell for about $12-$15! I will say I never saw the hole in the barrel channel like the OP's. Maybe his is an oddball.

My bad bro’s I wasn’t paying good attention to the period. I saw the first pic of the B channel route and assumed that it was earlier. Studs are correct
