VSC Phantom, trigger shoe, polished power tube, valve slug
Tighter bore than the Phantom stock barrel.
Tight bore, availability for Phantom
I got this as my first Phantom upgrade and it has served me very well. Small bore paint that will roll out the Phantom stock barrel is kept in by the Microshot.
Detent rings for the Phantom are often suggested as a cheap way to keep small bore paint in, but I have found that having a well matched barrel improves the guns accuracy and keeps velocity more consistent.
The porting on the end is very different, being what I call "Swiss Cheese". It serves to quiet the gun and I have found my Lapco barrel is no more detectable by sound than the stock Phantom barrel.
Barrels rarely perform miracles. The Lapco Microshot does its job very well. I think it's worth a 10 out of 10.
