Cheers Steve! I knew it was here somewhere. Just got me a huge 3700 battery - hope I can cram it in the Thompson.
You've got nothing to ein, zwei, drei, vier
You may have to take the stock apart and shave the runners it sits inside, so that the stock doesnt prize apart. Also on the door at the back (which you open to get the mag out) may need to have the locking component taken out for the length of the mag to fit.
Cheers Webby. I didn't realise it was a monster battery.

Yeah its pretty mega, makes my Classic Army Scar shoot a high cap in no time at all.
Dont have to charge it as much though
