Luke-1418 Posted August 8, 2021 Share Posted August 8, 2021 Hey guys, looking to upgrade my CRB into a DMR, I plan on increasing barrel length to 430mm with a Prometheus barrel and increase FPS to as close to 500 as I'm able to get without changing anything in the gearbox, yes I'll be locking to Semi dont worry as otherwise in the UK that thing would legally be becoming a firearm Anyway, what would be the best spring for me to get without changing gearbox and any other small things I can do?

Excal1burUK Posted August 9, 2021 Share Posted August 9, 2021 Possibly a m120/30 spring but it will put stress on the gearbox so other parts will need to change Link to comment Share on other sites More sharing options...

Some sites restrict DMRs to 450FPS max limit. Link to comment Share on other sites More sharing options...
Shamal Posted August 9, 2021 Share Posted August 9, 2021 That's true. 450 with couple of seconds between shots.👍 Regards Link to comment Share on other sites More sharing options...

Some sites restrict DMRs to 450FPS max limit. He's listed RIFT Comms Site 3 who say: Quote DMR - Semi Auto Only MAXIMUM of 500 FPS 30 meter minimum engagement rule. 2/3 Second delay between shots / wait until the first shot has landed before firing again. Semi Auto LOCKED - please report to a Marshal on the Day. (typical battery operated or HPA Semi Auto Weapon) Side Arm/SMG required for CQB. So yeah, 500 is fine. Personally I'd go for reliability over out and out power. Given the required shot delay and MED there's no real advantage over a bolt action which would be easier to make reliable at that muzzle velocity.
