Hey Guys,
I currently own a ICS-21 (Full metal M4) which I bought a few months ago.
I've used it about three times and have already noticed a drop in performance especially in terms of range and accuracy, what are my best options with regards to fixing this/upgrading?
I'm also keen on the idea of replacing my hand guard with a RAS/SIR however I understand I can only use RAS's made by ICS and have been struggling to find any online, any help would be appreciated.
Cheers.
