"Bought this baby on sale to play with friends, I love it but was a little too hasty and didn’t realize it was a Mk18 ( has shorter barrel) until I unboxed it. The orange tip doesn’t come off voluntarily so if you want it off you’ll have to break it off. It’s held up very well and would recommend to beginners. It’s kinda loud because of the short barrel, but not a big deal.

"I got the M4A1 Carbine / Black about a year and a half ago and for $159, it runs with zero problems. I haven't owned many other AEGs, but based on how well this performs, I think many of the AEGs I purchase in the future might be Specna Arms. They are super underrated, and I love running it. It can really take a beating and I recommend it for everyone, not just beginners.

"I love this gun (Model: M4A1 Carbine / Black). Specna Arms knows how to make high quality stuff for lower prices. This gun has been through a lot and with the external modifications I have made, it looks like it's been through a war, and it still works as if I just got it. I recommend this not only to all beginners, but even more experienced players.

"I bought the tan m4a1 back in 2021. Three years later, this thing is running perfectly. I put an aftermarket RIS, tube sight, broomhandle grip, and flashlight on it. The QuickChange spring is great. It runs perfectly on 2s lipos. The polymer receiver feels great, almost like metal. The quality is outstanding; I haven't broken a single thing in 3 years. The only problem I have had is that it does not shoot when exposed to cold weather for a while. Replacing the O rings should fix that. 10/10 AEG.

"This is THE best M4 for beginners in 2023. I’ve seen plenty of others online recommend it as well, including Evike themselves. It has good internals and externals, and by swapping the hop-up bucking and nub, it’ll much more accurately. I cannot stress this enough- if you want an airsoft M4 without dropping upwards of $200, this is the best gun you can get. If not an M4, try the CYMA CM040, CM045 and CM048 series.

"I’ve been researching for a _$200 AEG for a while and finally landed on the Specna Arms Core series. I purchased the C011 and it has been great for me. I have yet to field it, but I have fired at least a 1000 bbs and it has done well. Now to the pros and cons.

Pros:
-Metal hand guard
-Metal Mock Supressor
-Pretty good rate of fire
-Mine came with an X-ASR mosfet (I’ve heard some dont, but I’m not sure)
-Can hit a human sized target pretty consistently from 130-150 feet
-Not heavy

Cons:
- High cap magazine would stop feeding after 3-5 shots and was very wobbly (easy fix with a bit of electrical tape wrapped around it)
-Loud like a nail gun (can be a pro)
-May have to purchase other mags preferably mid caps like I did

Overall, great aeg and I hope to field it soon!

"I purchased the M4A1 tan version on sale for $89. Although I actually got the M4 SBR black version when it delivered, which I like more, it preforms very well out of the box. The trigger response and range/accuracy performance with a 9.6v NIMH is great! The externals and internals alike are very solid. The gun you get for the price is superb, you also get a lower power spring to switch with the standard one using the quick-change spring guide. Highly recommend for any air softer!

"I bought the C12 and I love it so far, great gun.

Pros:
- Spring so you can change FPS
- Shoots amazing
- Overall great gun

Cons:
- Stock is uncomfy
- A little bit heavy

"I have had this gun for about a year now and have had zero issues with it. Even used it in the winter at about 24 degrees with no issues. It is all polymer but still can take a beating. It’s been slammed into a few trees during play. This is my go to gun when my much more expensive guns give me trouble, which seems to be often. I am pretty impressed with the overall quality and would recommend as a good solid starter gun.

"Trying to set all emotions aside when write reviews but stock, this replica is excellent. With the original spring I was hitting man sized targets no problem at 100 ft without touching the hop-up. The only thing I found as a problem was that I could not get it to feed hi-cap magazines. I ended up using Echo 1 mid-cap mags and they’re perfect.

Downsides to this replica are that it has a polymer upper/lower receiver and buffer/stock tube which worries me a little. For a beginner, this gun is great.

Pros: works better with 11.1v LiPo batteries vs the 9.6v NiMH that IS INCLUDED.
The weight of the CORE is almost perfect For CQB. It gives the weight feel for replica accuracy

For how much effort specna puts into their licensing, that extra effort could be put into material quality such as, at minimum, aluminum receivers. They put stickers and what look like fake QC sheets in the box. If you’re willing to look past those things, definitely a solid replica!

"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.

"Bought as a first gun, good value overall. Love that it comes with a lower spring to meet indoor field requirements. Feels sturdy and shoots well out of the box.
A couple cons:
The mosfet in mine disconnects pretty easily when I install the battery and try to close the compartment. The extra wiring gets in the way, so the shortest the stock can be is on the 2nd setting.
You'll need a barrel extension to add a tracer unit, because the inner barrel sticks out about 2 inches from when you unscrew the "flash hider"

"very good as a starter gun, don't feather the trigger too much or you'll destroy the cutoff lever like I did.

Pro's:
Good Price
Good Performance
Good overall
the stock trigger break
VERY accurate

Con's:
cutoff lever is weak.
some mags don't feed well

"The Black and Tan Archer came with plastics that are one shade of tan, while the barrel shroud is a darker tan.
Really wish they didn't do that. The quality of the gun is exceptional for its price point though.
