It has been a long wait but well worth it.
I was planning on a real battle to remove the fake can but to my surprise 15 min into the project I had it off.
Thanks HKPRO for all your guidiance.
For other Coharie owners, spend the money on a RCM complete bolt head. Simply an amazing difference in how the gun runs. Spent brass dribbled out of it with original bolt head even after replacing with 223 extractor springs.
Now the brass is thrown 10 ft from the firing position and runs flawless.
Now I am waiting on a three lug adaptor for my Trident. When that arrives project will be complete.
Then on to the next project!
