Specna Arms meets the expectations of clients by presenting the CORE™ line of products - an exceptional series of replicas that introduces a new quality to the market. An attractive price in combination with an innovative spring change system as well as high-quality materials make this replica suitable for beginners and seasoned airsoft players alike.
The receiver, stock slide, handguard and a SF stock that holds the battery, as well as the pistol grip, were made from nylon reinforced polymer. Remaining components such as the barrel, flash hider, enlarged charging handle and tactical sling swivels were made of metal (parts made of steel include the screws, pins, shell ejection window and mock bolt carrier). The receiver bears markings and a serial number.
The replicas parts fit very well together and the User will not experience any loose spots between the lower and upper receiver. The use of a light polymer receiver allowed for a reduced weight, which makes it very suitable for dynamic games or long-lasting mil-sims. Whats more, fiberglass reinforcement makes the receiver also more durable than polymer and metal receivers.
The replica features a ESA™ Quick Spring Change System. Due to that system, it is possible to rapidly and quickly adapt the power of the replica to the conditions expected on the playing field without the necessity to have the access to a workshop or a set of special tools - all that is required is to remove the stock slide in order to gain access to the spring so that it can be removed without having to pull out or disassemble the gearbox.
The advantages of ESA™ system are hard to overstate. In the light of the current internal regulations inside various groups, the system guarantees the User a varied set of possibilities and plenty of freedom. ESA™ system allows with a minimal amount of time to change the main spring, thusly customize the muzzle velocity towards the area of the game in such a way so as to guarantee an ideal compromise between the effectiveness of fire and safety for the User himself as well as other participants.
The replica is fully compatible with LiPo and LiFe batteries. Due to a base muzzle velocity of ~380 FPS provided by the main spring installed by default by the manufacturer, the replica is perfect for operating on a medium range. The set also includes an M90 spring, which allows reducing the muzzle velocity to ~310 FPS and as a result to adapt the replica for close-ranged and indoor operations.
The gearbox contains 8 mm slide bearings as well as shimmed steel gears based on them. The system is secured with four anti-reversal latches. A light, made of a polycarbonate polymer piston is equipped with a full steel strip, in order to increase its durability. Also, implemented were a type 0 cylinder and a steel circuit-breaker, as well as a precise rotary Hop-Up chamber. The durability of parts allows for the cooperation with M140 springs.
The precisely-made rotary type Hop-Up chamber perfectly fit with high quality 6,03 precision barrel. The use of precision barrel has a positive effect on the range and accuracy of the replica.
The replica is equipped with a 22 mm top RIS rail and an adjustable stock. The top RIS rail features a classic transport handle along with a rear sight. Due to the extendable stock with an anti-slip stock pad, it is possible to adapt the replicas length to the body type and preferences of the User. A standard flash hider is based on 14 mm left-handed thread, which allows the attachment of a silencer in its place.Length:

"my core series m4 is great! i would definitely recommend to any new airsofter that may be looking for a rifle to start with. the only cons is that evike doesnt tell us that the gun indeed comes with a 9.6v nimh battery and standard wall charger, it doesnt come with the red dot sight seen in the pictures, but it does come with a vertical foregrip, so you can attach it if you want. i dont use .20g bb's, you can get 0.25g bb's and theyll work just fine. i was trying to manipulate the rear sights because there seems to be two rear sight pictures, but it is really tough to do because the sights are metal. you get a 300rd high cap magazine, but if you want to play more, you might want to get a couple extra SA branded midcaps or highcaps. the gun is full metal and ive actually scratched my hand on the buffer tube a couple times but the gun is very afforable and practical for us beginners
"Very good for the price. Shoots almost exactly 380 just as advertised, externals are nice for a polymer gun. Can hop even quite heavy bbs (like .32s).
The only thing that was kind of unexpectedly bad was the "quick" change spring system. Getting the buffer tube back on after a spring change can be quite difficult if you've rewired your gun. If changing your spring quickly is really important to you, stick with an ICS Split Ver2 model, although I'd argue this gun is better than their sportlines in most other areas.
"I got this rifle (SA-C03) in Labor's Day Box of Awesomeness.
Out of the box the quality is great. Good weight considering is almost all plastic/Fiber glass. Mine came with nun-chuck battery and simple wall charger, description says it does not includes them, big plus here.
Magazine holds 300 rds and feels also good quality polymer, not heavy, has texture that gives it a good grip, specially when taking it out of the mag well. Installing and removing the magazine on the rifle, feels rough but gives a snug fit.
Shot a few rounds at home and is very quiet. Iron sights are very accurate, even though I tested it at short distance. Have not had the chance to go out and test it at longer range.
The feature of replacing springs "on the fly" is appealing, will try to replace the one extra that comes in the box later, but according to the manual, I only need a flat screwdriver.
Like I said, I got this together with a Really nice Colt 1911 GBB pistol replica in the Box of Awesomeness this week, can't complain!!
