My origional bolt that came with my lucky stage 2 and 3 was messed up, but due to lucky's awesome customer service I got a replacement in about a week.
Uppon opening the box and holding the stock bolt and the stage 1v3 bolt side by side you notice a huge weight difference.
After firing I noticed less drop off and a more consistant rate of fire with less air than with the stock bolt.
works perfect with the stage 2 and 3. I highly suggest getting all three stages together.
If you plan on using this bolt in the stock firing can, you must use the stock bolt stop as the one that comes with the 1v3 does not fit.
I dont see this bolkt getting as much attention as the L6 or Firebolt, but in my opinion it works awesome, and is the perfect bolt for the stage 2 and 3
