I have the Brimstone tier 2. It was sent at the end of April & I received it back today. It has a 2lb pull & a very crisp release. It is not a match for my two stage Kidd triggers but for the price I consider it an excellent value.
When I sent it to Brimstone the lady at our Post Office filled out a customs for & I stated it was precision paper punching machine parts being sent for modification & signed the form. All in all a very easy process.
