New to airsoft? Here are some safety tips for airsoft guns that we recommend following.

The Blackside is one of the latest barrel extensions released from Mad Bull Airsoft under license with Gemtech of Boise, ID. Gemtech has long been known for the quality of their silencer designs and have been in use with numerous branches of law enforcement and the armed forces. The Blackside will fit on most airsoft guns with a 14mm counter-clockwise thread. Each barrel extension is constructed from high tensile strength aluminum and engraved with licensed Gemtech trademarks. This barrel extension is an excellent choice to disguise an extended inner barrel while keeping the weight on the front end down.

Length: 155mm (6.10")
External Diameter: 35mm (1.37")
Thread Type: 14mm Counter-Clockwise
Thread Position: The edge of the barrel extension
Recommended fit: M4, M16, AUG, SCAR, MK36, MK5
Color: Tan

Features:
Extra Light Weight
High Tensile Strength Aluminum
Licensed by Gemtech

Please Note:
The Mad Bull barrel extensions have no suppressive ability.

Product Information:
Better than I expected. I picked up a VFC SCAR-L in tan last year (which I love and highly recommend) that I have mounted an EOTech 552, Rico vertical flashlight grip, and a Noveske KX3 - all in black, so this year I'm going tan for the external pieces and this was my first.

I had the stock "standard" outer barrel with the KX3 on the end which looked bad a$$ but I wanted to go CQC so I tossed the outer barrel, dropped in the short inner barrel and put the KX3 on the end. It looked pretty good just a little short so I picked this suppressor up to compensate for an extra 4" or so and it's PERFECT! Longer than the Noveske but shorter than the standard length barrel. The "Blackside" IMO is the perfect length, it's nice and fat - it looks really mean, the tan shade is an acceptable match the the VFC SCAR-L and really just looks great. If this type of scenario is what your going for click "buy now" before they got on back-order.

Pros:
Perfect length
Nice and fat
Has a serious genuine heavy feel
Paint job feels and looks mint
Laser etching is spot on
Theading was perfect, almost feels impossible to cross-thread

Cons:
Would have been nice to have the trademarkings on both sides

Honestly, that's it
