This bolt was very light weight and worked very well.
The design and making it so light.
I was very pleased with the product at first, found it to be extremely light and work very well. But when i had just got mine someone else at the same field as me had theirs break in exactly the same way this one had. I hoped it was just their one that had some problem but that turned out to be incorrect.
So overall the design to make it so light is actually a bad thing and has brought out a major weakness in the bolt.
Check out the photos at the start of all the reviews to see my one. Should be pic 6.
So in conclusion i will not be recommending this bolt to anyone after 2 have broken identically.
