"1st review!! This one's worth the time. So far, the Aug High Cycle is the BEST short/medium range AEG I have had the pleasure to own (out of the box, that is).
ONE DOWNSIDE: The flash hider.
I've owned/used my Aug-High-Cycle for 8 months, unmodified for 2 of those months. I bought the A-H-C for Marui quality (which it lives up to) and because I was in the market for a bullbup S-B-R. with a high rate of fire. Well, I made one "modification" first- I uh, replaced the stock flash hider with a uh, cooler looking one. Which is the ONE DOWNSIDE to this whole gun: for everyone going the extra mile and replacing the flash hider, be ready to invest some effort in removing it. Don't even try to boil the glue, you'd be fighting a pack of gorillas with a warm super-soaker. The AHC is a very, diligently, orange-colored weapons system. And taking stars off just for that would be cynical, right? The way I un-oranged it was by buying a $5, 3ft steel bar, poking it in one side of the flash hider & out the other, and then using about 2 ft of leverage to twist it off.
280fps (@ .2g), 25rps, 200ft range, 6.08x280mm inner barrel, sluggish trigger

So far, hella durable. Just don't put a li-po in or you'll strip the piston. I'm using a heavy scope but the (plastic) sight rail has remained sturdy. The sling mount left of the butt is getting a little loose, and the bottom-front rail mount got a little loose, but set just fine with some gorilla glue. The sights are ok and an optic can help, but I seem to be more effective just following the spray of this thing. The real "durability" of a Marui lies within the consistency of its nozzle/hopup/barrel assembly, keeping your shots right where you remember them from last weekend! So it has good (but not great) precision, and with .25g bb's it achieves first-round-hit on human-sized targets out to 180ft. Add its consistent, responsive Marui hopup and its crazy ROF (25 rps, vs 12-18 for most AEGs) and your 2nd, 10th, or 50th round is very likely to hit someone out to maybe 220+ feet. It is sturdy, light, short & controllable, with plenty of rail space for attachments. The plastic receiver/buttstock is competently designed but it leaves me craving more detail work and is bit shiny for my taste (but, that's AUGs for you). The charging handle feels brittle but makes a satisfying sound when released. This is a terrific competition weapon, very ergonomic, very easy to aim, and very easy to carry in the ready position. Though I do crave that extra, legal, 100fps. I can just barely fit the smallest madbull grenade launcher on the bottom, and when loaded, it only mildly changes the weight/balance. I should mention, I have never used this with a hi-cap mag, only 170rnd mid-caps which have never had feeding problems. Conceivably a hi-cap could fail to feed at this rate of fire but I haven't tested. But if you're in the market for a bb tracer unit, get top shelf (Marui, again) models because only the good ones can keep up with an Aug High Cycle!
MODIFIED (I built my own gearbox, leaving the original intact as a backup. I suggest leaving the original gearbox alone):
370fps (@ .2g), 55rps, _250ft range, 6.03x363mm inner barrel, speed(ier) trigger

So... admittedly I utterly rebuilt this gun. It's... well I'll just say it's a DSG named Scrambles The Death Dealer. It took to modification very well, better than any AUG I've bought. I fit a matrix V3 gearbox in with no trouble (not so with an ASG AUG). Just as easily, I can put the original Marui box in and I've got my old gun! There's not enough space inside for a truly monstrous battery, so I drilled a hole in the side and ran the wires into a buttstock magpouch holding the battery. A tightbore gave me a moderate increase in accuracy. The sight rail has remained sturdy. In terms of modification the drawbacks to the gun are the small battery compartment (not uncommon), and the trigger mechanism (special to the AUG). The trigger was the *ahem* difficult part. Long story short, while I was blowing AEG wiring/firing parts like crazy I decided to make the whole effing thing from the ground up, including the trigger. Also, 90% of my engagements are semi-auto, where the AUG has a disadvantage because the heavy trigger mech is probably modeled after an infomercial bowflex. There's something a little sad about such an ingeniously constructed brawling weapon having a Flintstone trigger (some would instead say ultra-modern dual-stage gearbox-independent firing mechanism control, but I just think it's heavy). It's not the heaviest, but not good. After ~50 hours of headaches I've got a much lighter, shorter one. I would not suggest going that far though, and the AHC is certain to take care of you (and the baddies), no question.
