Well to make an "awesome" snipe, performance wise will take around 300$ to put in a decent piston,spring spring guide, and cylinder. To just fix your problem buy the replacement trigger set off Gi. I have a Tm vsr-10 that has well over 1500$ in PDI parts and a Prometheus barrel and i still have some problems being able to consistently hit some one at more than 200ft. Sniping looks cool but unless you have some training on how to move and do recon it really isnt practical.
