Retro Arms CNC Machined Aluminum V.2 / V.3 Air Nozzle (Size: 19.5mm)

"Got the 19.5mn version for my friend Dyatc ak Krink paired with an ASG Cylinder head, works great and good seal and feeding

"excellent nozzle. 21.4mm fits well in my CYMA m16a4. o ring is not pre installed so you will have to put it in yourself which isnt hard if youve got a pair of tweezers, was fairly easy with my ifixit tweezers. air seal was perfect. no leaks

"This nozzle has been my go to for all of the recent builds that I've done. It has an inner oring and fits up nice to all of the cylinder heads I've tried. (ZCI, Prometheus, retro arms, and SHS)

Highly recommended

"I put this on my lonex cylinder head and had no issues at all except some fitment of other parts of the cylinder head. This is a great nozzle to use for high speed, dsg, dmr, or in general getting good fps.

"This nozzle is slightly longer than a standard v2 nozzle (0.16mm longer). Sometimes, it causes a feeding issue on my VFC G28.
