It’s an alkaline shell and everything else from MMM
at the tip of the gun i switched the red to yellow and it will be getting a repaint soon
Just wanted to know how it rates and what should be done to it
Thanks
Overall its a nice pack and looks to be well built. The only issues I have are with the finishing touches, the main being the silver drybrushed weathering, silver painted over black rarely looks good and just looks “off” to my eye, probably due to the screenused packs being made of fiberglass and not having any silver chips. If you can id remove all the detail parts and spray her again with satin black then once dry reassemble and use fullers earth to lightly dust the pack, will look ALOT better imo. repeat for the gun too.
Apart from that id paint the ion arm cap block black, cut the orange tips off the elbows, shorten the green hose on the thrower, swap the yellow hose for red on the guntip and use the correct bolts on the booster frame.
All those should help make a nice pack great 
Nice pack. But, you should fix that PH-25 resistor.. The gold nut should be on the inside of your Ion Arm leaving only the top visable and giving it extra support.. Like this..
I trimmed the orange tips off of my SMC elbows, and then painted the elbows with gray primer. This made them look more accurate. Adding some brass washers to your thrower handle will add some nice detail as well. Don’t forget your n-filter label!
Gb2 packs didnt have a label on the N-filter 
You’re right, Nick! I guess I’m slacking on my studying! I’ve seen a few members with labels on their GB2 filters, so I’m assuming it couldn’t go either way?
Labels go on the N-filter for GB1 packs that were converted to GB2. So you’re not wrong.
thanks!
yeah the drybrushing didn’t go as planned and I didn’t even notice the resistor
Change the screws on the booster frame,they should be cap head screws that attach the booster frame to the booster tube.
