LED Counter for HCG Pulse Rifle

[jaybee]

Hi

i now own a HCG Regular Brown Bess Pulse Rifle.
I found some interactive LED counters from different vendors (to have a decreasing ammo amount on pulling the trigger of gun and/or grenade launcher, with and without sound, from Lightbenders and such).

Is it possible to add such an interactive counter to the HCG PR?
If so, has someone already did this and is there a manual how to do this correctly?

I am looking for same - found this FK926 Two Digit Counter Circuit

and this - which looks really straight forward
Electronics Projects: Two-digit LED counter using PIC

I know this is a historic link but it was unanswered and covering same problem I have been thinking about

Matsuo on the RPF has had previous experience tearing those apart and making modifications, however , just saying,,
if you attempt to take it apart be very aware , damge will and can occur to the grenade launcher as well to detach the shroud on the PR's........iif someone can correct me on this , please do....
