It should be able to work. When the PM6 first came out, people were putting aftermarket PM5 Orange bolts in their PM6 with no problems. The PM6 came with a LP bolt guide/cap, which is the only difference that I can see.
If you heard a loud pop, and it leaks out the barrel, then the #013 oring popped out of the groove on the tophat. This can happen if the input pressure is to high.
I have an air Leak through the barrel
There are three possible o-rings that cause this leak:
- If the leak comes through the inside of the bolt, replace the #013 BN70  on the bolt top hat.
If the cause is the #013 BN70  o-ring, the input pressure to the gun is likely too high.
If you hear a loud pop while firing the marker and air is rushing out from the front of the gun, it means:
- The Hyper2™ is set too high causing the #013 BN70  top hat o-ring to blow off, replace the o-ring.
- The #017 UR70  inside the bolt cylinder or #020 BN70  outside the bolt cylinder is leaking, replace the o-ring.
