I have a brand new never fired Surefire SOCOM-556-RC that was approved last month. Prior to the can being approved, I purchased an all Colt M4A1 upper from a fellow ARFcom member. The upper came with a FH556RC-1/2-28 (4 Prong) Flash Hider already installed.
The can will not fit all the way onto the 4 prong and I'm curious if anyone has ever experienced this before?
The can fits onto my other Surefire Socom adapters just fine: 3P, SFCT, SFMB, & Closed Tine Warcomp.
Here are some pictures. You can see how far the can will slide on before it basically would have to be forcefully pushed on. You can also see where it has taken some of the finish off of the 4 prong.
Thank You in advance, I appreciate any helpful responses/information. Maybe it's out of speck? Maybe it's a really good fake?
Here are two photos showing how the Closed Tine Warcomp fits and locks up fine.
