Archived [ARCHIVED THREAD] - Info on Picture? Piston conversions on Mk18s?
Posted: 2/16/2017 1:50:51 PM EDT
Found this online, what appears to be M4s and Mk18s with piston conversion bolt carriers.

No exhaust vents at all on the carriers.

So does anyone know anything about these? I wasn't even aware any piston kits fit under the RIS II.

Ahh you may be right. I forgot about that thing.

So used to seeing the simunitions rounds.
