i have a .177 dynamax and i love it!!! yes it was a bit loud but i purchased an ldc from tko and it is very nice.
give him a try. as for the single shot tray i have also looked for one. i made one for my maurader and i will prob make one for my max. i dont mind the mag that comes with mine. as for fps mine ave around 1000 and so far i have not had any bad shot strings. anyhow i hope i helped somewhat. i do love my max.
