>>6116047Are thrift stores (secondhand/donation) stores a thing over there? You could pick up a Buzzbee Tek 4/Tek 6/Tek 10 and harvest its spring. It's these revolver looking blasters that were supposed to compete with the Maverick. Despite having a direct plunger, the plunger tube was narrow and tiny, so they put a 6-7 kg spring in there to compensate; stock Nerf blasters come with a 2.5 kg spring. This shouldn't cost anymore than 3 burgers and you always see them at Thrift stores or garage sales stateside. Then pop out the back cap on your Retaliator and a few screws then thread out the original and swap in the new one.
