Super Varmint has Tikka's 2-stage trigger, bolt knob, and a pic rail. The photos look like the barrel is threaded - why else would there be a knurled cap on it.
The original Varmint I had shows as discontinued. It was much cheaper than the Super Varmint, but I had to add a pic rail and bolt handle and the tupperware stock came out of the box only long enough to be replaced by the MDT chasis. I replaced the single-stage trigger spring and had the pull down to a crisp, SAFE 24 ounces.
He said Tikka Tact A1. I tried to get him close to that. I started PRS competition with a TAC A1 in 6.5CM in 2017. Fine rifle. Accurate. So I bought the Varmint and put it in the MDT chassis to have a cheaper-to-shoot "trainer." Knowing what I know now, I'd have engaged an outfit like Southern Precision Rifles to advise me on building a custom from the get-go for a similar investment and not be locked into the Tikka ecosystem.
