"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 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.

"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 just ordered this (still waiting) but I’m very excited to get my first airsoft gun:)

"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!

"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!

"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"

"It is very reliable I have put more then 10,000 rounds through it and the only problems with it is the mag it comes with sucks, and you can't spam the trigger on simi-atuo, it will lock up and you might have to switch it to full auto to get it to fire again but it isn't a problem if you take your time to aim. It can hit a human size target 180 feet away, a soda can 50 feet away easily and has good rof on full auto. It was awesome back when it was in stock and 30 dollars cheaper, but now it's just ok. The double eagle calaco Jack cost the same or less now and it is just as reliable and accurate with a much better trigger, you can spam it on simi-atuo as fast as you want

"I may have gotten a lemon but this gun was very sub par. Very poor qc on the externals, horrible airseal. The shimming was alright and the aoe was nice and the price point is good, but I'd say save the money and get something a bit higher end

"worked great actually the best fps ive seen for a gun at my fields limmit in my experience but it only got through less than 1000 shots with a 9.6v before it stopped feeding full auto and jammed constantly, waiting on a refund request as ive used it for maybe 8 games bought it in may and asked for a replacement in august a bit over due on the free warranty but ima see what happens,
idk if i can recommend it or not obv because it didnt even last half a year while keeping it well kept and the only thing ive really touched that coulda caused minor scratches was removing the muzzle to change the rail system as the muzzle its way too big to remove the hand guard
