This efficient new system only requires the removal of your buffer tube castle nut to gain access to the captured guide rod and spring. No longer is it necessary to break open your receiver or even remove your stock from the buffer tube to change a spring.

Patterned after the original ArmaLite AR-15, this venerable weapons platform has gone through numerous updates and evolutions through the years to become the go-to choice for military personnel, law enforcement agencies, and civilian shooting enthusiasts alike.

The Daniel Defense licensed RIS II handguard is a free-floating, two piece, ultra lightweight front rail system. It provides a full length mounting surface for all 20mm Picatinny compatible accessories: From grips, lights, PEQ boxes and anything in between. The handguard system is designed to accommodate an M203 grenade launcher with no special tools required.

"This guns build quality is absolutely amazing.
The only gripe I would have is that the hop up is not the best, I have put a flat hop bucking and nub in and it’s mediocre now.
Other than that the gun is awesome I use a 7.4 titan lipo and the trigger is super snappy and rate of fire is good.
I personally swapped my rail system out with the Daniel Defense 4inch kit that’s in evike so I can use it easier indoors and all day because this rifle is HEAVY.

Overall would recommend it if you’re looking for great external build quality.

"First things first, this is the gun I bought to get back into airsoft. I haven’t played in years and years, but now that I live in an area where I can attend mil-sim games easier, and constant nagging from buddies I finally caved.

With that being said, I’m blown away! Things have definitely improved since I last was into the hobby. I’m not a tech, but as soon as this got delivered I took it to a friend who is a tech. We split it open and went through it, and man this thing is sweet! Construction is fantastic, and it’s a very solid weapon.

Feels extremely solid in the hand, absolutely no wobble in the stock or other areas. Compared to real steal, the pistol grip is a little slick to me and the ejection port cover is definitely made from some thin Chinesium, but those are easily remedied. I do feel as though the real DD RIS II’s are slightly more solid, but this thing is great for the price considering real steal RIS II’s can go for the price of this whole weapon.

Again, I am no airsoft tech. I did purchase a different motor, bucking, and barrel when I originally bought the weapon based off recommendations from a friend who knows his stuff. When we took this thing apart, we were definitely surprised at the quality of components installed from the factory. The motor is pretty much good to go out of the box unless you really want that extra torque or MAYBE longevity. The nozzle is trash, like what others have said. Definitely had larger than desired variance in FPS and pretty lack luster compressions, all of which seems to stem from the nozzle. The piston and cylinder head both seem good to go, the nozzle is 100% the issue. I’ll definitely be upgrading, and I recommend you do as well if you buy this thing. The gear box was decently shimmed, but it won’t hurt if you get yours re-shimmed. The hop up seems pretty sheisty, mine doesn’t work as badly as what others have reported, but it leaves a little to be desired and I’ll be upgrading that as well. I would also recommend upgrading the barrel to get that extra FPS especially with .25s. The dean’s connection is a nice touch and welcomed. The crane stock leaves tons of room for a battery. I’m able to fit 2 1450 MAH 11.1’s in the stock.

So out of the box, this thing was shooting at about 280 with .25’s. Obviously that’s not what we’re looking for, but can be fixed easily as well. After squaring away the compression issues with a half-assed o-ring fix at the piston head and a new barrel, I’m right around 345ish with .25s. Again I’ll be changing out the nozzle which should help even more with compression irregularities.

This thing does have a mosfet and micro switch trigger, both of which are a nice add right out of the box. Semi is snappy. Using 11.1 lipos with mine, and I’m curious to see how everything holds up, but as of right now I’m feeling pretty confident this was a good investment.

For 300 bones this thing is pretty legit, and with another 60 bucks you can make this thing even better. I will definitely recommend this weapon, and look forward to breaking it in at our next event.

"Cycles and sounds just like my other two cyma platinums. Haven't cracked open the gearbox but assuming it's 13:1 gears short stroked 4 teeth like the other plats with some of the best shimming out of the box I've seen. These benefit from an o-ring nozzle upgrade right out of the box but perform fine without doing so. Haven't gotten a chance to test it out in depth as it comes stock and I most likely wont bother before rhopping it etc. I've seen others say the stock nub is soft and can lead to a lack of hop. If you want to use it out of the box as is and want to run slightly heavier ammo just throw in a stiffer nub. This has a functioning bolt catch. One thing I noticed is that the gearbox shell isn't coated black like my other plats. Instead it's silver and seems to match my brothers cyma sr16 gearbox shell with functioning bolt catch.

Externally the gun is worth the money alone. The dark earth model just looks insane once you get the ugly orange flash hider out of there and pop a stubby on it or whatever you're going for. Can't speak for the reliability of the etu but again it will be upgraded anyway. These are things you should consider if you don't plan on upgrading it though. Basically buy it if you're into the DD mk18 look because this thing pops differently than your average DD repro rail thrown on an m4.
