Very impressive from what I got on initial results. Previously my Tikka had issues grouping with heavier berger 6.5 ammo, once I got it dialed and did the "tuner test", my best groups came with that ammo and the barrel tuner attached.
There is a thread here where a few of us have shared results, including the 10 shot group tests, but lots of odd attempts to derail the conversation by people who seem to objectively have some issue with the idea of using a tuner.
I'm running off memory but did weigh it before installing mine several months ago. The EC Tuner and adapter combo weighs a little over 9.0 oz and is considerably heavier than the KSS ATS which is a little over 5 oz.
