The Proximity barrel is definitely the one you want. It's basically the same length as the Ionfire's detachable barrel, it matches the Dual-Rail barrel, and you can easily buy one for $7 USD or $9 CAD on Amazon. If you want that with a pretty sick looking red dot sight and an awkwardly shaped VFG then you might consider buying the whole kit that it comes with, although I'd say the standalone price for the barrel is alright.
