WE Apache barrel replacement

[Tank423]

Hi guys

Attempting to change barrel on my Apache tonight and have come across an issue no one else seems to have raised in the searching I've done.

The original barrel has 2 locating notches but all replacement barrels I've seen including the raved about crazy jet are all single notch, so are people filling down the second notch for barrels to fit?

Am I missing something glaringly obvious?

Thanks

The crazy jets are not single notch , IIRC they actually have 3

I filed down the 2nd notch on my hop unit in my WE Scar H to fit a crazy jet. 

Figured I’d rather (potentially) ruin a £10 hop unit rather than a £30 barrel. It is easier as you know exactly how much material to remove in the hop unit and can test fit as you go. 
 

10mins dremeling and it was sorted, barrel is still securely held without the second notch

Exactly the answer I've been looking for, I thought I was going mad not realizing something that should be glaringly obvious.

The second notch in the hop unit was really throwing me off as all the VSR/GBB barrels I have are all single notch and all the searching I've done about replacing the barrel no one has said about filing anything down.

I'll give it a go tomorrow as I'll be cutting down a spare tightbore to fit anyway so will have all the tools out.

The pictures I was looking at must have been VSR barrels as they were all single notch, another Google has shown me more with the triple notch. That'll teach me for not being more thorough

Your replies are much appreciated guys thank you!
