To my knowledge the multishot base will fit all versions of the TRMR. I have two different versions and my base fits both
Cheers for the info. just curious as the one i have only has one firing pin... which isnt offset at all and not knowing how the bases work i assume the firing pin changes position on the multishot bases?
btw.... the TRMR e2 will not accept the multishot base according to JD-Airsoft. http://prntscr.com/kygxj6
