Threaded barrels are useless in competition games. The shot timer records each shot by the report of the firearm.
We have had some try to shoot suppressed during matches and it doesn't work.
The threaded barrel would be for personal use.
Yes, I have seen a number of videos where shot timers were ineffective/erroneous because of the use of suppressors. I guess I should have made myself clear. By competition, I meant commercial/business competition among the firearm manufacturers/industry and NOT individual shooters/sportsmen.
