Please note: this is not a thread adapter. You will need to disassemble your marker and replace your stock barrel adapter with this upgrade.
For the 98 version:
This adapter lets you put your 98 barrels on to your A-5 paintball gun.
Q: Can I use this to put a 98 Flatline on my A-5 gun?
A: Well you can but the shroud won't fit and the performance through multiple adapters will be pretty poor.
Q: Can this be used on an X-7?
A: This adapter will install on a stock X-7. 98 threads are larger and won't fit in the front of the shroud. So for install and removal of the barrel, you'll have to remove the shroud. Also be aware of the length and external milling of your aftermarket barrel for clearance.
Q: Will this fit the old and the new 98 Threads?
A: Yes, it doesn't matter how new or old your 98 barrel is. This adapter will work.
