ICS M4 Hop / after market barrel
Hi fellow ICS M4 users,
I have a plastic Hop ICS unit and I want to install the MK18 rail / barrel on the rifle. I purchased a no name brand BIG DRAGON MK18 outer barrel - and the plastic hop unit seems to slide in fine without thinning the wings. However, it doesn't slide all the way in, just stops halfway.
New barrel needed or modification needed?
Ideas?
