Wow what a cap!
I was looking for a cap that would fit some of the other smaller bangers I have and it works great. The bottom part will fit into a banger with a ⅜" or larger opening, with the bubble being around ¾". (These are approximate measurements.)
But if you pair it with a MJA Deep Round Bottom Cold Start banger you won't want another banger... js
Perfect pair, great cap🔥💨💨
