[MRCA] [spam] Re: [ARC5] BC-221 on Shock Mount

[Michael Hanz]

Sadly, no, Jeep.  It was designed specifically for the BC-221 series -

I was hoping the TS-164 shock mount I've occasionally snagged would fit 
the command set modulator, but of course not.  Its dimensions are just a 
little bit different...
