This breech may seem like a god-send, but it comes with problems. Does not have any o-rings inside the breech (size 17) and you need two. A lot of people had trouble with the bolt shooting forward and air blowing threw the barrel because newbies dont understand you need the sft o-ring. Also the holes for the trigger frame right beside the barrel threads are not machined properly(in my case) so i had to re-drill it so the screw could go all the way in because the barrel was getting scratched and caught by the screw. Pretty inconvenient if you ask me.

i absolutely love this barrel breach but i did have to buy a new barrel because it was not the original threads but it is an upgrade in my opinion.

Do you need or want a new breech kit for your Ion? If you said yes then this is the breech for you, inexpensive and makes your Ion autococker threaded, the most commonly used barrel on the market! These warrior breeches are nicely built and good looking. They are durable and they are a great upgrade for any ion!
