"This gun fires well and seems well built. The hop up is proprietary but it works well and I really like how easy it is to adjust up and down. The piston is polymer or nylon, not sure, with a half rack of steel teeth. The first tooth is skipped to allow AOE adjustment which is also nice. The piston head and cylinder head give a nice seal but the stock nozzle does not have an o-ring.

In case you are worried about some of the proprietary parts to upgrade:

My model came with a polymer nozzle that many people online recommend replacing for a better air seal between the piston and nozzle. Testing the included nozzle there was not perfect seal, and air leaked out the sides. I ended up replacing the nozzle with "SHS Aluminum Air Nozzle for AK Series Airsoft AEGs":


This nozzle fit perfectly into the gun, fits into the proprietary hopup unit, fits the tappet, all with no adjustments. I'm just putting this part in for anyone looking for an inexpensive part to upgrade for good performance increase.

"Love this rifle! Had a buddy install a Prometheus Flat Hop Smooth Bore Hop-up Bucking and he flat hopped it and wow! But be careful... any upgrades and you're going to DMR it real quick. I get constant chronys at 430! Also, I would recommend nothing but 11.1 lipos... 7.4's sound and react a little sickly with this gun. The stock motor also tends to heat up during heavy play, but this had not affected the performance of this gun. 11.1's are snug in the stock and this has a tendency to push to stock cover plate out of the stock. Easy fix is not to adjust the stock to far in. Right now Evike has the gun at $217! That's a steal if you can get it, plus it just looks great and it turns!

This rifle is amazing. I bought it from my local shop, very excited. i was not disappointment. right out of the box, metal receiver, sturdy stock, and good trigger response. i run mine w/11.1 lipo, and the trigger response is AMAZING. Rate of fire is snappy, and range is 150-180 feet with a .2 accurate. very pleased with this rifle.
1) the split gearbox
2) all metal
3)good weight.

1) proprietary hop up, upper and lower reciver. ( but not bad, its really good quality parts)
2) you dont own one.
an excellent rifle, that i am superbly pleased with
