For: MadBull Gemtech Raptor II Barrel Extension for MK5/H&K MP5 3-Lug Adaptor OnlyProduct Information:
It took a long time for me to justify spending over $50 on a hunk of metal that adds no true performance upgrade to my loadout. Even harder to justify it to the Treasury Department (aka "The Wife"). With that said, this is one finely crafted piece of aesthetics. I have an Umarex MP5A5 RIS by G&G (love it) and this suppressor fits perfectly on the 3-lug barrel end (after stripping the heavy orange paint from the MP5's adaptor, but that's for another review). It clicks on with minimal effort and feels rock-solid. It doesn't add too much swing weight to the gun, but it does obviously add some length - something to keep in mind during CQB.
If the time ever comes that I need to upgrade the MP5's already-good stock accuracy, the Raptor II gives me the option of putting a longer barrel inside. However, for now, I'm very content to use it just as a cool-looking piece of kit.
*Solid connection - no wobble
*Quick and easy attach/detach
*Sweet Gemtech trademarks
*Completely useless unless upgrading inner barrel to a longer length
*Price is still a little high, personally
*Extra length makes it easier to "flag" your muzzle during CQB
