The SR-47 is a modern assault rifle based on the AR-15 family of rifles created by Knight's Armament Company for USSOCOM. Unlike the majority of guns based around ArmaLite design, the SR-47 is essentially an AR-15 that fires the Soviet 7.62×39mm round from AK-47 magazines, which explains the "47" in the gun's name. The rifle was created after soldiers on long missions in Operation Enduring Freedom complained of running out of 5.56×45mm NATO ammunition for their M4 carbines but having plenty of captured AK-47 magazines. The SR-47 is basically an M4 that will accept standard AK-47 magazines rather than NATO STANAG M16/M4 mags, along with other minor modifications common to KAC's designs.

Overview
This will be my 3rd SR47, I’m not sure if they’re as appealing as my FN SCAR’s or I just am curious on the newest releases. Just before Christmas 2019, Evike listed a brand new SR47 replica made by CYMA, and a few months later I noticed another new listing for a Sportline model. When it went on sale for $109, how could I say no.
The CYMA “proline” model with the QBS (quick change spring guide) system was a fairly good gamble. I still hold CYMA in a low tier thanks to my experience with their checkered history and their extremely cheaply made AK’s with poor quality control. However, the QBS is at least comparable to most other brands nowadays and so I had high, but reserved, expectations of this Sportline model.
So here we are with a review of the CYMA Sport AR-47 SR-47 Airsoft AEG Rifle (10” Quad Rail).
As soon as I picked the box up out of the larger cardboard box Evike shipped it in, I knew we were in for a long review. The rifle was still wrapped in plastic, but loose BB’s could be heard. Upon opening the plastic the BB bag was cut in half, I’m not sure what this rifle has been used for but it clearly isn’t “new.”
I was also surprised to see the old style foam tray from 10 years ago, rather than the current EVA type foam that many other rifles come in.
Accessories
After rounding up the loose BB’s, it was clear they are a mediocre and unpolished .20g BB.
The magazine is a standard metal hi-cap, unlike the QBS that came with a Magpul style mid-cap. I was expecting a mid-cap, but a mag is a mag. Interestingly the box is cut out to hold 2 mags so perhaps there are other releases out there.
The standard manual is included, as well as an unjamming rod. Nothing special about either, so let’s press on.
Externals Review
Let me make this clear…a lot of this rifle is plastic. Some of it is nylon fiber reinforced, and some is cheap ABS plastic. So I will try to outline what is durable Nylon Fiber Reinforced Plastic and what is ABS plastic. This is not to say ABS plastic is poor quality, but that some parts are better reinforced for strength.
The flash hider is a standard blaze orange plastic M4 birdcage covering a 14mm negative metal outer barrel. The flash hider was not glued in and held in place with a allen grub screw like most replicas. Rather it was glued in (very well) and pinned with a roll pin. There will be no saving the flash hider when switching to a different one.
As mentioned, the barrel is actually metal, although at first, I thought it was a metal and plastic hybrid. The coating on the exposed area is very nicely textured and colored. The gas block is plastic and CYMA seems to have tried to link the RIS to the gas block with a screw in the lower RIS. The gas tube is a nicely formed rod and looks realistic under the RIS.
The RIS is nylon fiber and feels very solid. There is some flex in the RIS, though it is hard to tell if it comes from the RIS itself, or from the D-Ring. Both are nylon fiber and feel very solid, but they do have the level of flex which should be expected in a plastic body. I have confidence in its durability to withstand use, especially since CYMA tied it into the outer barrel with the gas block. However, I think CYMA poorly reinvented the wheel as it’s an unnecessary, and complicated, design.
The main body is also a sturdy feeling nylon fiber, with a great matte black finish. I dare say it is on par with G&G’s Combat Machine bodies. The selector positions are neatly laser engraved with Safe-Semi-Full Auto. There are also 2 stickers and a lightly engraved serial number, but otherwise the body is blank.
The selector and faux bolt catch are also nylon fiber, though the mag catch is fortunately metal. While I find it cheap that so much of the rifle is plastic, nothing has been compromised in the manufacturing, the rifle feels solid throughout, even the plastic selector.
The front and rear sights are similar to a Troy and KAC design respectively. The front sight is similar to a Troy Battle Sight and the rear is a KAC stick design it. Predictably the KAC stick has terrible eye relief. Even worse is both sights are made of an extremely cheap and thin ABS plastic. Unlike every other part of the externals, these feel like junk and will probably break off at the first game.
The pistol grip is very nice. The nylon fiber reinforced plastic again feels very good, and the texture was comfortably aggressive. Unlike the QBS that comes with a copy of the Magpul MOE grip, the Sport model comes with a standard A2 grip. The motor plate is also nylon fiber but is at least vented. The adjustment screw slot has a threaded collar built into the motor plate, from there you adjust the allen grub screw as normal.
The stock is also made from solid feeling piece of nylon fiber reinforced plastic. It is a basic crane stock, except for the front plugs that are no longer separate and allow for easy access to the stock interior. Instead you have to take the stock off and pull out a screw that holds the plug piece in place. The stock pad is a very nice feeling rubber and snaps firmly in place.
The stock tube is a standard 6 position tube and is the only other major component of the externals that is metal. Unlike the QBS tube, it is a standard AEG design and easy to replace.
Internals Review
The hopup is similar to the Evike Challenge kit hopup (which is a clone of the original Hurricane SR47 conversion kit for a Tokyo Marui M4). The long curved shape of the hopup chamber allows the use of AK mags with a feed nozzle towards the middle of the mag to feed into a version 2 gearbox that normally feeds from a M4 mag with the feed nozzle towards the front of the mag. Unfortunately, the Sportline model comes with a flimsy feeling ABS plastic version that leaked pretty bad upon testing. The barrel and C-clip were covered in what I can only guess is red threadlocker. However, the gears were tight and did not move easily so that might be a plus over many other hopups.
The barrel acts like a 6.03mm tightbore and roughly 330mm long, which is an annoying custom length. It is a nicely finished red anodized aluminum which is different; but doesn’t offer any gains.
The bucking came from the factory torn (see performance review). Which is terrible QC and assembly. In terms of first glance quality however, the bucking appeared to be soft and would have provided decent range had it not been initially damaged.
The motor is as basic as it gets. It barely wanted to turn the gearbox, but it did so out of the box.
Honestly I was expecting a bone stock, bare bones minimum gearbox when I ordered this rifle. What I got came as a complete and utter shock!
What I missed when removing the stock tube was that this gearbox has a Quick Change Spring Guide, which can be accessed through the lower receiver after removing the stock tube.
Second of all, Evike also fails to mention that this gearbox comes with an electronic trigger! I’m wary of the system, only because it is proprietary and if it ever dies you won’t easily be able to toss in a replacement. However, it works, and gives a great trigger response, especially for a $109 rifle.
Unlike the QBS gearbox, the Sport was not drowning in grease. I was pleasantly surprised to find everything appropriately greased. The 8mm bushings were packed with grease, but it was strangely a different type of grease than the stuff used on the rest of the gearbox.
The QC spring guide changes the shape of the shell somewhat. The cylinder corners have been pre rounded to reduce the risk of breaking. There is a window cut out to gain easy access to the anti-reversal latch, though this is unnecessary since the spring guide can also be quickly released. Finally, the lower portion of the shell where the magazine sits features a guard over the front of the gearbox. I don’t think it does much as far as the gearbox or magazines are concerned, but it’s an interesting addition.
The unmarked gears are an odd high torque ratio, and worked during testing. They appeare to be tempered as well. I’m not sure if CYMA did this because of a high tension spring or to prolong the gearset’s life because of poor metal quality. The shimming was surprisingly almost spot on with only the bevel gear needing a minor addition. Like all factory AEG’s this needs to be checked to ensure long term durability.
The piston was a disappointment after reviewing the QBS. The Sportline comes with a standard piston, and unfortunately no Angle of Engagement (AoE) correction and will quickly self destruct if left unchecked. Sadly the piston head was also plastic, and had no bearing.
The cylinder is a type 0 unported which is overkill for the 330mm~ length inner barrel, but it is at least reasonably well polished.
The cylinder head was a very loose fit, and like the QBS head, the nozzle end was strangely elongated with no apparent reason for it.
The tappet plate is the same blue plastic of the rest of the gearbox. It works, but I prefer to have fiber reinforced plastics.
The air nozzle appears to be an M4 length (or at least close enough) nozzle, but does not include an o-ring.
Performance
FPS: 380-392FPS
Range: 160ft~
Usually Evike lists the FPS higher than my initial test shots, but this time they claimed the rifle to between 350-370FPS. My initial chrono tests put the rifle in a respectable 383-392FPS. With the 330mm~ barrel, the rifle is capable of typical 160-180ft of torso accurate range. There’s plenty of places for improvement, as after a proper tuneup, the FPS dropped to a consistent 375-377FPS with AoE correction and air seal checks. Unfortunately, with stock parts it didn’t get a perfect seal, but the seal that was achieved after tuning is almost perfectly consistent. The range was disappointing. The hopup was soft and uneven pressure was applied with the stock nub and broken bucking. With a good bucking and nub combination I would expect to see much better results if tested again.
I will mention that the stock motor leaves a lot to be desired, with the cheap motor and high torque gears the RoF was abysmally slow on a 7.4V LIPO. However, the trigger seemed to be ok with a LIPO so this is potentially one of the first true LIPO Ready AEG’s. Certainly one of the few truly LIPO Ready AEG’s that I have reviewed. I’m uncertain if the electronics will survive an 11.1V but it did nicely with my test 7.4V
Final Thoughts and Upgradeability
Since the SR47 shares more in common with the M4 than the AK, there is virtually no end to parts available for the rifle. Externals abound, especially since the Sportline uses a standard AEG stock mount, unlike the QBS version. I am very impressed with this little rifle, especially for the price tag.
Externals Score: 9/10
As mentioned, the Nylon Fiber Reinforced Plastic feels very good. The rifle has metal where necessary and everything feels solid. The only places I can take points away is the overly complicated gas block that makes disassembly a pain, and the useless iron sights. The sights are so cheap and flimsy I’d be more understanding if they didn’t include any at all.
Internals Score: 8/10
Again, I’m finding myself a fan of the stock CYMA internals like I did with the QBS gearbox. I am concerned about the electronic trigger burning out and not being able to replace it, as well as the high torque gears, junk motor, and torn bucking is also a disappointment and loses them another couple points.
Overall score: 9/10
I’m going to go ahead and give the overall rifle a high score. Having recently worked on other CYMA products that are just as new, but non-updated I have to say it’s strange to see such innovations such as the QBS or the Sportline with a modern gearbox. While I still have reservations about CYMA quality control, I do have to give them credit and give them a good review for pushing their products to a new level.
