||Before I give my review I'd like to give some pointers before you buy.
If you have a short barrel like I do (G&G Combat Machine short raider) you MUST buy a "Matrix Steel 4.5" Outer Barrel Extension for Airsoft AEG (14mm Negative / Counter-Clockwise) only $15" b/c the thread on this silencer is close to the center, not on the edges.
If you have shorter barrel it will add an extra 9.5inches/241mm.
If you have the longer barrel it'll work fine but will only extend your length by 4.5 inches/114mm so if you're planning to upgrade your inner barrel select your inner barrel accordingly.
The silencer looks nice and has engraving on it that says:
"3rd Model MBS JBU INC. M4 CAL 6mm SER NO. 03007" it's not colored so you can barely see it.
And for the reviewers that say it does not add any silencing, it does a little. The gearbox is still loud but the sound from the front is dampened a little.
When I took it to get it chrono'd customers at the airsoft shop complimented the silencer. So it's definitely nice looking when installed properly.
I would suggest getting but since I felt that it is incomplete (meaning I had to separately purchase the 4.5inche outer barrel extension) I give it a 4 star though this shouldn't discourage you since you've been informed :o)
