"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.

"1 year review.

Price: paid $169 a year ago for this exact model, so it seems to have gone up $20 which might be a sign of the quality and demand for this model.

Pros: solid, never let me down in a year of playing 6 matches almost every weekend. Good enough space for battery, including nunchuck.

Cons: mosfet shuts down after repeated fire on semi with 11.1v batteries, and have to flip to auto then back to semi to get it working again. solid metal hand guard hurts when you accidently bump other players with it.

"A good gun, very light, fun to use, when i have used it has had no issues, except that i purchased the wrong kind of battery, which i fixed easily by getting a new one.

"Model: M4 RIS
BB Weight: 28
Hop adjustment: 3 turns
Upgrades: none

After 15 times on the field, I'm very happy with the accuracy and reliability. Typical stock long trigger pull makes it tough going up against the binary trigger crowd but I get my share. No complaints at all.

"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.

"Specna Arms SA-C06
Out of the box, a great, lightweight M4. Tough for being an all-plastic gun, runs great with a 7.4 or an 11.1, but if you spam the trigger a ton on semi-auto with an 11.1 the electronics may lock up for a second or two. The stock being plastic on a plastic buffer tube has a bit of the classic M4 wobble, but it is easily corrected with some well-placed electrical tape. Battery room is adequate, make sure you run a Deans, as the supplied adapter can make for a snarl of wiring that can make collapsing the stock challenging. The pop-up sights are great, all metal and adjustable front and rear. Remove the inner dust cover or you will have to hold the charging handle back to adjust the hopup.

I bought two as loaner and trial guns to see how they did for the sub $200 gun category and they are great intro guns. I just converted one to HPA with a Redline N7 Milsim and apart from a minor bit of grinding in the gearbox shell (wire guides by the trigger assembly) it is quick and relatively easy, and you can keep the safety!

If you're looking for a great, inexpensive M4 this is a solid choice

"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:)
by Clay S. on 03/18/2021
"I got the SA-C01. Great external build quality. Even though everything except the barrel is plastic, it felt like metal. I never had the chance to test fire it because I replaced literally everything inside of the gun as soon as I got it. Just be ready to clean out your hop up chamber and barrel because they put too much oil on it.

"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!
