Turok's CQB to standard length question
Hello, Im thinking about changing the outer and inner barrel of the CA M15A4 CQB to something longer. Im thinking about getting a:
1. Prometheus/Systema/Modify 6.03mm, 363mm inner barrel
2. Madbull 14.5" outer barrel.
Will these two upgrades fit my hop up and my existing CA M15A4 CQB? Thanks for your help guys!
