G&P Skull Frog Keymod M4 Carbine Airsoft AEG Rifle w/ i5 Gearbox (Package: Black + Add Battery/Charger)

"I would rate this gun overall as a 4/5, but for me this gun is a 5/5 because of the quality of the externals on this gun. I have had this gun since 2018 and it was the first high end airsoft gun I purchased and I was not disappointed with my purchase. From other reviews it seems that people had problems with the i5 gearbox, and so did I. The website isn’t very clear, but the i5 is meant to do full auto rather then semi auto. I used this gun more as a dmr with its longer barrel, and in doing so fried the internals. I took the gun to a tech, and the motor was swapped but the gearbox broke again. I used this as my excuse to get into hpa and dropped an amped airsoft gearbox with a Kythera engine. I also installed a different stock, Maxx hop up, maple leaf bucking and rubber, a zci 6.02 inner barrel, and a tracer unit, and after upgrading the entire gun, it is flawless. While the only stock parts are the externals. This gun shoots laser beams, but if you want to keep it as an aeg I would recommend using it mostly on full auto, and only use an 11.1 lipo, as it shouldn’t be used with anything other then an 11.1 because the lower voltage won’t power the gearbox. It also comes stock with a programmable gearbox where you can program it to have safe-semi-full, safe-semi-3 round burst, or safe-semi-9 round burst. Look up on YouTube how to program that, but at the end of the day this gun is worth the purchase. If you’re looking to fix something on the gun, I would get a better gearbox, as the i5 was good on paper but not in practice. It’s not a terrible gearbox, but there are definitely better ones out there. I recommend this gun because the externals are amazing and if you fix the internals this gun will never fail you.

"Great gun and rail system can’t complaint anything about it awesome gun

"This gun is amazing! When I got this gun delivered to me I was very pleased. It has beautiful externals and great internals it has great range and a good fire rate to match.

"Awesome gun so far, haven't been airsofting with it yet with it but the rate of fire is insane and it shoots great, this is my first AEG and i'm not disappointed so far. battery slot is a bit small, that is a valid complaint but im not worrying about it, I can get my 7.4 LiPo in without too much of an issue. Overall I would definitely recommend. One other thing is the dust cover wont shut but from what I've read G&P dust covers aren't meant to shut

"Fantastic gun!! Superb internals and beautiful externals, the trades are very nicely done both on the receiver and the rail system, internals are great as you can expect from g&p over all 9/10 simply because of the buffer tube is only a 5 position

"Love this gun for looks and internals. This gun is really solid gun, reminds me of my real steel AR. I really love the keymod rail on this gun because it's low profile I can really get a good thumb over bore grip. The rail covers are a rubber texture that not only feel great but grip well with or without gloves. Now I will say GET a 7.4 lipo. I found out the hard way that this style crane stock DOES NOT store crane stock style batts. Battery is stored in the buffer tube. Last thing I'll say bout the body is that if you are going to mount a quick release optic i.e a t1 telex repro it is going to have some play. Out of the box great internals. For a stock barrel and hop up this thing shoots like a laser. One thing though I'd install a 110 spring. This gun does shoot hot. My local field is 400 limit and I'm at 410 415 with .2s. I really love this M4 out of all my other brand m4s. Buy it!

"THIS GUN IS AUSOME LIKE ANY OTHER G&P BUT THE RESONE ITS AUSOME IS BECUSE IT HAS THE SAM INTERNOLS AS SAILIENT ARMS GRAY SO I HERD

"Great Gun But... Be careful

I got the gun, gun didnt work. Brought to my local shop, and wiring harness was broken. So thanks Evike for not testing the gun before shipping.

Any ways after it was working...

Gun is Great - First shots range from anything around 380 - 440 fps (.2g bbs). For some reason this gun likes to have the first shot when cronoing around 180fps. After that it is around 400 fps ish. Tight mag well, so I recommend G&P magazines or Valken. G&P Mags fill the Mag well and wont slip. Valken Mags will some times slip. I recommend all metal attachments it will make the gun feel more "Real" and heavy. For long days of fighting I recommend a sling. The mock silencer is more of a cover for the long barrel. So if you expected a shorter barrel you could cut it off.. but I dont recommend it because it will be great range. When I was playing with it for the first game I had longer range then most of the snipers at the game.

The bad, like before bad wiring harness, only thing I would make sure is the gun works first. Evike just needs to make sure to test before sending. 2 The weird FPS every once in while the weird 180-200fps for one or two shots then 400 fps. 3. Battery Compartment, its in the buffer tube with the wire. SO very small space for battery. SO recommend a small stick 7.4v with 20cc normal 40cc burst. It sticks out of the gun a bit but the stock covers up the part sticking out so it works.

Overall great gun, 4 out of 5 due to the harness issues and fps issues. Recommend attachments, Metal Grip, G&P Mags (Hi Cap), Eo Tech Sight, With Flip Magnification, 1 or 2 point sling and 7.4 small stick battery. 380-410 fps with .2 g bbs. about 365 - 375 fps with .25g bbs.

"Great gun overall. Fantastic rate of fire with a 7.4 lipo and a very good looking and nice feeling weapon overall.

Pros:
Great rate of fire
Full metal receiver and handguard
Full top picatinny rail system
Ambidextrous magazine release
QD sling points and one included sling mount
Easily adjustable gearbox

Cons:
Not a big fan of all the white markings all over the receiver, but that can be looked past
Left handed magazine release gets stuck often and is not smooth at all
Some magazines have a hard time fitting into the mag well; have to be forced in
Not much battery space in the buffer tube
This could be a pro for some, but I had a small tamiya style battery. Gun is wired with deans connector

"The gun itself feels solid, it's beatiful, and it feel so damn good in your hands, but...in the end of the day it only gave me nightmares. I was so hyped up for the i5 gearbox only to be left extremely disappointed. I never even got the chance to fully use and utilize the gun because of the number of problems that keep happening. It was making this crunching sound whenever i fire, it misfeeds, and the trigger would sometimes lock, not to mention it drains your battery fast! I sent it back to evike for repairs in which they replaced the gearbox entirely, but after getting it back the gun just wouldn't work anymore and would only make this grinding high screeching sound that the gears would make. I'm sad to say this, but I would not recommend guns with the i5 gearbox in them. I have also ordered the GRY with the same i5 gearbox and also encountered the same similar problems until it a part of the piston chipped. I now have sent mine to a local airsoft tech for fixing. Totally not worth the price for this gun.
