I've had mine for 5 months, I've used it on 5.56, 300 blk, 6.8 spc, and 260. The mount is great and sounds good in the long and short configuration. I've been using it a lot lately on a Tikka ctr 260 and the poi is repeatable when removing the can and putting it back on. Accuracy is just as good or better than shooting without the can. The only downside is the weight, but it is built very well and I don't see ever needing the warranty because of a problem with the material or workmanship of the can. I'll be happy when my Razor is approved for when I want to shed a little weight, I'm sure it will impress me just as much.
