Tikka T3 Scout / Ching Sling Setup

[jneher]

Hi,

I recently purchased a Tikka T3 Scout in .308. I'd like to
try a Ching sling on it which requires an extra sling
swivel stud just in front of the magazine well. At this
spot on my rifle is a little round metal (3/8"?)
circular plate sunk just a touch into the lower
handguard. This looks like it was provided exactly
for the purpose of installing another sling swivel stud.
However, before I drill into it, I'm wondering if anyone has
experience with this (or other Tikka Varmint-Style T3')
and can tell me if this is indeed the right thing to do.

Thanks,

Jon
