I've read that they fit, but feel like thick ones might not. Recently both of my stems shattered so no hammer time.
And if I buy hammer stems its almost 20 for two lock ons, in my mind I might as well buy a screenless stem or a gong stem for about 40 because of shipping. And my logic here is I can get $40 off my UD purchase because it comes with four stems.
I think I just want a plug in vape because I went ahead and bought it, even though I know I don't need it since the hammer can do the same job and paytonpenn has the proof! I'd honestly be fine with just my mflb, it's just a little gunked up over the years
