darn near same stuff I told you when you wanted a slp. only the vinci is as reliable as the M2. The M2 is the gold standard. The load port is great.
$80 for a long tube vs. vinci for $270. M2 is metal to metal. vinci is plastic to metal to plastic. Vincis receiver can be reshaped for an optimal loading setup, but its a pain (ie takes time) to work plastic and not make it look like a rabid beaver gnawed it. Vincis can be made into a great 3gun, its just that M2's can do it faster, stronger, cheaper, and we have a 30 year proven track record for the M1/m2 gun.
If thats what you want scotty, go for it, Its ok to zig when others zag, if youre a zagger!
