What is the FPS limit for sniper rifle here Because my sniper rifle is TSD Tactical SD97 Bolt Action Sniper Rifle The FPS 490-530 and my other sniper rifle is WELL L96 Airsoft Spring Sniper Rifle For this one FPS is 440

This field uses energy limits not FPS, it's 1.5J max for normal guns and 2.0J max with 50' minimum engagement distance for snipers. Rule of thumb to be below the limit is 4OOFPS with 0.20g BBs for normal guns, and 460FPS with 0.20g BBs for snipers.

400 for an aeg with a 10ft MED. 490 is rather high and I think it caps out at 470 FPS with a .20g bb. Sheriff is the airsoft reff and he is typically a little lenient and will work with you though.
