This adapter lets you put your 98 barrels on to you’re 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 shourd. 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.
