So today I purchased an 2003-2005 ICS M4, with a Classic army SR-25 Front-end. I knew the gun wasn't in the best condition but for $75 I thought it was worth it for the rail system.
I knew the barrel assembly was not comparable with the ICS and required modification to install. I did not know however that the threads had been dremeled out in addition to the "barrel nut?" being tapped for set screws.
I soon found out I could separate the "barrel nut?" from the Ris.
I hoped to use the ris to complete my Classic Army DMR. So the issue is, can I buy another "delta ring?"/"barrel nut?" to replace the damaged one.
If anyone has any other ideas I would love to hear them.
Thank you for your time,
