The barrel received (after 5 weeks) is longer than the description. It protrudes 25.4mm or an inch from the front of the barrel as opposed to 10mm advertised.
Chrono testing with the original barrel showed results around the 340fps.
Chrono results with the tuning barrel all showed upwards of 440fps, the highest being 486fps.
Testing was done with Kratox, Ballistic Devestators and glass breaker nylon rounds. Kratox and Ballistic were very disappointing showing below 300fps so we stuck with the nylons for maximum velocity.
Overall I'm very happy with the performance improvements of the tuning barrel and also the added Mad Max look to the TR50.
I'm looking into purchasing the suppressor in the future.
Well done to the team at Home Defense 24!
Envoie rapide et de bonne qualité !
