About the MadBull Whisper Barrel Extension

The Whisper Barrel Extension by Madbull/SOCOM Gear is a stubby mock suppressor or barrel extension. You could use it to cover up a slightly protruding inner barrel or add some style to the end of your muzzle if you have a flush forend and you want to give it that monolithic look. This is great for pistols too as it does not add a whole lot of mass to the end of your barrel which can sometimes cause cycling problems in gas blowback pistols.

Though not based on any particular real world counter parts, we can see that the Whisper is designed to be a compact mock suppressor for .45 handgun like a 1911 judging by the markings. Could this item work in real life? We think that it could since there are some real designs that go for a short length tube but a wider can which makes up the volume issues and makes it perform like a longer can. The BREVIS suppressor which Madbull also used to replicate was that same type of short but wide can design and that is based on a real world proven design.

About Madbull

Madbull/SOCOM Gear (same company) is one of the first names in airsoft when it comes to quality accessories, gear, and guns that carry full licensing. In the earlier days of airsoft in the US you would get some off brand accessories that were pretty much unauthorized bootlegs if you wanted markings. Though it did not have anything to do with performance, only aesthetics, sometimes these individual items would get cracked down upon by the original makers and there would be some legal problems for those selling them. Whats more if you bought something that was acquired through unofficial channels product support is non existent and it is a dice roll on whether you got a lemon or something that actually worked. Now we're not trying to tell you what to get and how to spend your money but presenting the reason why this was a big deal when we first started playing. Now in the world of airsoft all the major distributors do everything by the most legitimate means possible so you can see how big of a deal it was. Madbull items are all made in Taiwan which is one of the top tier countries for manufacturing airsoft goods in our opinion (other big brands include ICS and VFC for example). They use state of the art computer aided designs, CNC machining, durable realistic anodized coatings on many of their products, and more. If you are looking for the parts to make your build the most legitimate, check out Madbull.

Honestly, this is the only airsoft shop I will ever buy from. Their guns are always quality. Their custom work is mind blowing. Their staff is not only helpful, but always happy to help. If you are just starting out or have been playing for years, these guys have guns, gear, and good advice for every situation.

Awesome company and products. Received sooner than projected from Colorado and I'm in California. Less than 2 days from placing order to receiving it. . Everything shipped as ordered . Incredible selection and great price... Did my homework and eventually came back to them. I'm glad I did. My squad will be ordering and I be ordering more gear as well.
