Are we talking a tri-lug suppressor? 
Nahh…not at this stage.
Just get rid of the large supplied flash hider, and fit the smaller tri lug.
More compact look…
Come on, are you a yanky. Mines better.
nice bro
though LDT is more expensive , its extensionable is good
errm ya what now 
you know , I’m new in here

I wonder how to add flag emoji on ID like yours

Oh sorry missed that. Go to your profile an edit it 
Hmmm…
My one and only piece… the Cyma Mp5 tri lug…
Has arrived in Oz, and landed in …
Syd…!! Where ABF will have my name up in lights…
Lets see, what they do, with this one piece of metal…
Next Time, i’ll ask them to declare it as…
" LGBTIQ 3 way sex toy piece, approved for use in pride festival"
Then, it’ll get expedited handling, and hand delivered by Bruno…!!
Well, that’s the risk you take when you live life as an outlwaw, BME. On the ragged edge as a person of interest, always looking over your shoulder
Oh and the LGBTQI+ thing? No judgement here. 
I can make a call but no reach arounds or else HAHA
A bit of subterfuge…!!!
More success in importing, if its something Sydneysiders like… ( not for me though !!)
Lets declare gel blasters, as…
" Rainbow sparkle joy orb dispensers!"
And see how we go…!

How’s that sound.?.?
As long as it’s red, orange, yellow, green, blue, and violet that could work you know
I can just imagine ABF, wtf is this. Oh throw it in the bin. It’s easier.
Its one piece of metal.
Surely, it’ll get through…
fingers crossed.!
Should be right if under $100 aud and not for a real one and going to an allowed state.
Well, the tri-lug got through.!!
Good news on that front.
All metal piece…declared as " Gel Blaster parts"… so it made it through SYD ok…
However… it doesn’t fit on properly.
It must be made for airsoft, with a smaller diameter inner barrel.
The rear half of the tri lug is wide enough to fit over the gel barrel, but it tapers down in diameter ( for a snug fit on an a/soft barrel) and jams.
This looks like a job, for a drill press.!!
There should be enough meat on the inside…
Drill it out to a larger diameter…
Other option is cut protruding inner barrel off, by about 4 cm.
I don’t wanna lose barrel length…
