"Way better accuracy then the stock barrel, now my HPA'd P90 shoots dimes with the Promethious Purple bucking. Highly recommend

"Picked this up for my CYMA M14. My mistake for buying one apx 3cm short, BUT I installed it anyways as well as a new Hop-up Bucking. I had a fair grouping at 50m before changing at roughly 8 inch spread. New Barrel and Hop, it's about 3 In spread. (when the wind isn't whipping) Very happy for my DMR build.

"Upgraded my ICS MP5A4 with this barrel. No mod needed
