[Milsurplus] GRC-9 receiver disassembly

[Hue Miller]

Anyone here disassembled GRC-9 receiver, taking the front panel off?
I am wondering how accessing the lamp socket is done (if in fact it
can be accomplished. ) I have the crazy wondering how feasible it
would be to replace with a screw base lamp socket. The 1.5 volt 
flashlight bulbs deliver substantially more light than the feeble
TS49 at 1.5 volts.
The downside would be you'd need an ammo pouch of spare
flashlight bulbs; I read their rated life was in the low tens of hours.
