fyi.. the aluminum nozzles are back ordered from where I purchased mine (there aren't many that have them on their site yet). I was sent an email with the following.
"Please note that since WE aluminum nozzle takes long time to produce, there will be a couple of shipments. The 1st shipment (6/6) released about 25pcs and we have shipped each of them according to the priority of orders received date. The 2nd shipment, as estimated, will be at the end of June. Please patiently wait."
Definitely nice to get an email. I ordered mine around 5/26 so it will be a bit of wait.
Just an fyi if anyone else was looking into the nozzle or complete bolt.
