There are 2 silencers.
1) is about 10" long, foam rings inside and has a slight dimpling pattern on it. It may have a special forces emblem on it, I do not remember. No idea what brand. The other one is a copy of or is a G&P stubby killer and is about 5"? long with the foam rings and same dimpling pattern on it along with some wording. "Stay back 100 meters or you will be shot" or something like that.
There are 3 batteries left.
One of the batteries is a Firefox 11.1 12c 1200mah Fairly small
One is an Intelect 11.1 20c 1200mah? long and skinny
The last on is an 11.1 C rating and mah? and is very small. I think it is a King Arms.
Hope this helps.
