��This is a set of upgrades purchased in a single order from WGC. These upgrades include functional and cosmetic pieces - a Titanium inner barrel for the Tokyo Marui Glock 26, and a threaded metal outer barrel and fake sound suppressor. Titanium barrel upgrades are a relatively new thing for us since we don't usually do too much modification on our airsofts. The only other one we've done as of this writing is the Micro-Tec barrel in the Marui MP5K. As for the cosmetic upgrades, my favorite type of tournament is the "professional" tournament which is usually played with a suppressed handgun, and since the Glock 26 is currently my primary gas blowback, I figured I'd go ahead and rig it for use as such.
Appearance
��The appearance of the Titanium inner barrel is good; it's got a nice dull silver finish and it appears well-made. But as with most performance upgrades, once it's been installed you won't usually see it again. The threaded metal outer barrel has a dark grey parkerized finish which looks nice but doesn't match the rest of the Marui gun's finish. Not a big deal since mostly you'll only be able to see the chamber area resting in the ejection port. Interesting note: This barrel is made to fit a Glock 26 (which would be a 9mm), but the barrel is marked "40SW" which would mean it's intended for a Glock 27. Again, no big deal. It can be a 26 or a 27 as far as I'm concerned; they both handle the same. The fake sound suppressor is really nice - it's modeled after the Advanced Armament "Scorpion" covert ops line. This small suppressor has got a nice matte black finish and includes the "stainless steel" thread mount like the real ones do. It is marked realistically and says "Scorpion 40 S&W" so at least it matches the barrel. When the whole outfit is assembled onto the TM G26, it looks good. Really good.
Function
��Installation of the inner barrel on the G26 is a snap compared to installing an upgrade barrel on, say, the MP5K. Field strip the Glock and remove the barrel assembly. The inner barrel basically slides backward out of the outer barrel. It may need a little careful coaxing since there are tabs holding it in place. There is a single screw holding the left and right halves of the chamber together; once that's been removed the halves can be carefully separated to reveal the back of the inner barrel and the hop-up mechanism. Take note of how everything fits together before you remove the factory barrel. Once you've substituted the new barrel for the old, reassemble everything in reverse order from before, testing parts for fit and function as you go. The Glock 26 functioned flawlessly before and after the barrel upgrade; it seemed to have a little more power after the barrel swap.
As for the cosmetic upgrades, field strip the Glock again and pull the inner barrel from the outer barrel. Place the inner barrel in the threaded metal outer barrel. The fit on this particular outer barrel is a little loose which makes assembly easy but I wonder if it doesn't hamper accuracy. At any rate, reassemble the G26 as you would normally. When sliding the longer, threaded muzzle through the front of the slide, you may need to work it slowly back and forth the first few times since the threads have a habit of getting caught when going through. After the airsoft is back together, simply thread the Scorpion onto the muzzle threads. I find that having a small suppressor such as this helps my instinctive aim (and in fact it doesn't block the sights like a larger suppressor would so you can still take aimed shots as well). Everything works fine with the new setup, though it did take a little breaking in to get the slide to come fully forward after each shot. Having the slide on this airsoft a fraction of an inch out of battery doesn't seem to affect function or accuracy, so it's just a matter of firing a few dozen shots to get it back to normal. The only other functional comment I've got is that after rapid fire sequences, the suppressor may start to work its way loose since the threads are rather large. There are a couple of ways to cure this - the method I prefer since I'll almost never take the suppressor off is a small drop of Loc-Tite temporary thread locker. That way the suppressor is still removeable but it won't come off by itself.
Accuracy
��Accuracy didn't seem to change much between the two inner barrels, though the airsoft did exhibit a small increase in power. Attaching the suppressor to the threaded barrel drops the point of impact by about three inches at fifteen yards, but doesn't change the group size. I haven't messed with the hop-up settings at all yet, so there's probably a little room for improvement.
Overall Impressions
��Both of these upgrades were worth doing - the inner barrel because it didn't cost much, and the outer barrel because it looks cool and, in my opinion, adds to the handling of this small airsoft. If you're a fan of covert ops handgunnery, then at the very least the outer barrel/suppressor set should appeal to you.
