Matrix "Calico Jack" Polymer M4 Airsoft AEG Rifle w/ M-LOK Handguard & MOSFET (Model: SBR / M4 Stock / Black / 350 FPS)

"This thing is awesome. Only added a madbull 6.03 300mm inner barrel and a 11.1 and rocks almost everyone at the field. Stock with .28 mine sits right at 295fps. Swapped to a 115 spring and it's at 345fps now.

"Had this gun for around a year now when it was aeg the thing was amazing good trigger response good range fps everything it's a very good beginner only problem is that not many mags fit in it but I found a few that work so it's fine. I recently converted it to hpa with a redline n7 and it's so much better now. I did have to dremel out 2 support things in the gearbox but that's normal to do for the redline n7 but after that it fit ran and worked amazing I love this gun

"Fantastic gun. Trigger response is amazing and out the box this thing rips. Only downside is I’ve heard the tanker stock cannot be swapped for a regular stock due to the upper receiver being unique or something. 10/10 gun would recommend as the perfect starter.

"One of the best aegs. shoots very fast and it is very reliable and customizable

"10/10 entry-level aeg
The first AEG that got me into airsoft

Pros:
- Lightweight
- Programmable trigger sensitivity and Binary (use at your own risk)
- Lot of features for the price (Mosfet)

Con:
The full polymer version tends to flex, get a metal handguard if you can
- Nothing special except the gearbox

This is the thing you pick up if you are new, it gave me the best first 2 years in airsoft possible and only change/upgrade if it's broken.

You can buy one of the KWA polymer series if interested in more reliability.
They do lack a mosfet though (non-programmable stuff)
(The whole group runs KWA, I moved on to KWA ronin T10, might be biased)

"One of the best guns you can get for under $300 totally recommend!
Does not come with battery.

"Took this to a day long milsim event in the pacific northwest. Gun got dropped multiple times and i fell in the mud multiple times. Never had any issues and it shot well. Would recommend. Great for the price.

"This gun is a great for beginners light, strong, tight upper and lower receiver connector, no wiggle sounds exact for the stock witch they completely lied to us in the description because there is no room inside this stock for batteries. The only real problem that I had is the magazine that is comes with is wiggling around in the Magwell which was causing a lot of misfiring but this problem can be resolved by using electrical tape. If you were to upgrade this gun in the future you should consider a maxx m4 hopup unit because that units has a clamp that holds the bb’s Inside of the hopup instead of those three bb’s just falling onto the floor. I loved the computer inside of this gun because it allowed three options which involved
1. Programmable burst for full auto
2. Three different trigger sensitivities
3.double touch (which is were the gun shoots twice with each trigger pull on semi auto)
I can comfortably and accurately shoot this gun with 100 feet’s range and up to 200+ feet if you raise to hopup. There is a negative 14mm thread on the end of the barrel.
You can pull the orange flash hider off by unscrewing the key with an Allen wrench use pliers to unscrew it. (I will be tight because it is glued on) I’m also a little confused on how the upper and lower recievers separate because it gets caught into the bolt release
This gun doesn’t have much of an electric gun sounds it sounds very smooth for being a stock v2 gearbox. The grip get pretty hot but that is probably because I’m using 11.1v instead of 7.4v I’ve already shot a 1000 rounds through this gun on 11.1v and this gun is still running strong. I will say that this gun is 11.1v ready but use at your own risk because it could get too hot and catch fire. The gun is very snappy. For $165 this is probably one the best cab’s starting to begin with, very easy to put bb’s down range very fast.

"i purchased the polymer PDW

PROS:
Light weight.
good Rate of fire with a 7.4 lipo.
Trigger response time is very quick.
Adjustable hopup.
Compact for CBQ.
Quick change spring.
Programmable trigger system.

CONS:
Small battery space due to small stock.(i believe you can 3d print or buy an extender)

"First M4 model gun, and verdict: Go with this one if you can't find a better one.

PROS
Mostly metal build
Lots of picatinny space
Good quality magazine (not a wind up and its mid cap though)
Extremely accurate
Good iron sights
Adjustable stock

CONS
Not very much space for batteries
Battery makes it hard to put stock back in


Overall very good gun

"For me, it's a really nice gun. With an 11.1v battery, it shoots like a 300-350 rifle and the trigger response is crisp.

Pros
not very expensive for the performance
shoots amazingly
pretty light
sturdy

cons
many proprietary parts to worry about (I tried to buy an aftermarket outer barrel and it didn't fit with the stock barrel lock)
stock is wobbly for me

"Very good gun for the money. The black cap that covers the end of the stock comes off easy, but just don't use it. Much easier just to tape a battery (or two for a quick swap) to the side of the stock. Mine had pretty low fps out of the box, but adding a new spring was very simple...Remove the stock with 1 screw.

"AMAZING!!!! Love it..... Its just what i need as a starter in airsoft. Its so much fun and hasn't broken down on me yet... thanks so muck evike!!!!

"So we have 2 of these with the m4 stock, and double eagle m904h which is the same exact gearbox, longer barrel/handguard. We can fit 11.1s 1450mah batteries in them just fine.. Out of the box, we really liked these, the MOSFETs handle 11.1s just fine, and have a nice fire rate and the sensitivity on the trigger is very nice...
They shoot straight and are light weight
The MOSFETs are like a gate titan clone with optical sensors and have held up fine after 4-5 months with outdoor use almost every Sunday

Both calico jacks have experienced the same issues:
-Trigger spring both snapped and were replaced
-After upgrading to g&g m120 springs the piston o rings blew out.
- we've replaced the cylinder and piston assembly because the o rings on the piston get flat on the sides too fast losing compression
-one got a broken nozzle
-one had a motor burn out...
- the motors get hot so consider upgrading

"Got the tanker stock sbr 350 FPS version about 8 months ago, honestly a great beginner/ intermediate gun. Feeds great with .20 and .25 bbs, did have a little trouble with .28s but I rarely see people using .28s in aegs anyways. The tanker stock is really easy to adjust and has no problems sliding at all. My one and only complaint is that the battery compartment is quite small so all I can fit is a 7.4 1000 mah battery in it. The electronics are amazing. The burst and binary trigger settings are amazing. One thing I should also mention is that the spring takes some time to wear in. Your FPS will start at around 320 when you first get it but goes down to 300 over time


Pros: easy to maintain, many cool features, compact but still accurate, balanced weight

Cons: low FPS even for cqb, small battery compartment, hop-up is hard to make precise adjustments
