Having owned (and still do own) high end actions such as the Multiple Defiance deviants, Curtis axiom, bighorn tl3, Accuracy International... the Impact sets itself apart. The timing of the action is the best. Only a custom benchrest can perhaps be similar. It’s Soooo effortless to cycle the bolt. Cocking on closing can be self timed and is so minimal compared to other actions. Mine is paired with a foundation and Hawkins bottom metal, shooting 6 dasher. It’s crazy how smooth you will feed a round. Not a single action I’ve cycled has been that smooth when actually cycling a round.
Many people cycle their bolts and say, wow that’s smooth, and I’ll tell you all the actions I’ve owned and still own listed above I still have that impression; but, the impact action you will say, “wow that was sooo smooth”. Some of the other above listed actions will still have stuttering when advancing the bolt to pick up a round and while still smooth they are not impact smooth.
A buddy of mine whom never fired bolt guns just ARs and handguns, cycled all of my actions and I kept my mouth shut. He picked the impact as being the smoothest.
One feature that people need to be aware of is that the trigger hanger does limit what chassis can work. MPA no problem, JAE new versions no problem, the KRG whiskey 3 the low profile button head trigger hanger screws are needed, and even then I had to take my mag well bolt out. I’m sure I can find a low profile one but chose not too Bc it didn’t make a difference. The AI chassis will need inletting. Just an FYI... I decided to not mess around and go with the foundation stock. I guarantee you won’t regret it and you won’t see people sell their foundation, Bc they are super awesome!
