"I bought 2 of these. Both came with a mag, and one had an 8.4v nunchuck. One mag had camo ammo in it which I assumed was the cause of the problem. One gun just needed to be put back together and the other's gearbox was locked up. Couple hours later and they worked perfectly fine. These will make good gifts for my friends who don't have a gun.

"i recieved my m4.
it was a avenger m4a1 biohazard dark earth, i got to 9.6 nunchucks, a charger, 1 mid cap and a high cap, one rds sight.
the gun worked out of the box and every thing it came with worked, the gun has some gear issues that im taking to our local field so they can inspect the gun and make sure it works 1 hundred percent, i highly recoment you order 1 of these, high quality polymer furniture, metal inner and outer barrel.

"So I just received my rifle today, I expected the worst, I was surprised that it came with 2 mags 2 nun chucks a working reflex sight and a great that mostly shot outa the box, it fires great single fire but won't fire full, I'm taking it to my local field and see what they can do but for 40 dollar it's one of the best buys on here

"I picked up four or these. Besides the clean up I had to do inside and out( witch was substantial) they worked great. Two of them had missing bolt releases, but it was an easy fix. 5 out of 5

"I purchased three of these to fix up for my boys as back up weapons when we go out on full day games. Haven't had to use it as backup because our G&P never failed to last, but it did come by handy as a loaner for friends a few times. The three I got had a bad motor, bad wiring, and a bad magazine respectively, nothing hard to fix at all! Was expecting spare parts but I got three extra complete working rifles now!

"This gun is suitable for beginners or parts.

PROS:
Low price
Good for cheap parts
Decent motor

Overall, it is a good gun if you can get it for $70~$90 and knows how to repair your M4. Good for extra parts.

"Great boneyard buy! I received a dboy m4 AEG with metal gearbox that has a broken fuse! Easy fix! The magazine, and 99% of everything else on this gun works with my KWA and G&G M4!

"I have purchased 3 of these boneyard M4s, and for the most part, they are good guns. I would recommend these as backup guns.
All 3 out of 3 had the same externals; the all had the body as pictured in image 1. All 3 of them came with mags, 1 came with a battery, and 1 came with a charger. (It looks like the battery doesn't want to work)
2 of the guns worked out of the box with no maintenance.
1 of the guns had the motor wires backwards (lol).
Internal wise, 1 of the guns had a gearbox with a QD spring system. The other 2 had traditional Version 2 gearboxes. The last 2 I purchased (the most recent purchases) were the two with traditional Ver. 2 Gearboxes.
Gearbox internals:
All of them had plastic pistons (one metal tooth) and plastic piston heads. They all had cylinders with one teardrop port (equal to the area of about a nickel) and metal gears with metal bushings. The wiring was typical and all included in-line fuses with plastic fuse holders. The motors are regular stock motors, nothing special
The spacer in one of the 3 hop up chambers was loose.
One negative of these gearboxes is the screws! It surprised me that screws can be this s****y. The heads break off extremely easily.
On the QD spring system gearbox, the small metal nub that keeps the trigger contact from pulling back into the sector gear broke off. I tried to fix it, but ultimately it fell off again, so I decided to trash that gearbox (I have about 4 spare shells lying around)
All in all, I would recommend buying one of these as either a backup or loaner gun. There is no issue with compression with these guns, so a good hop-up set up will allow it to compete with $150+ guns, although it still has a plastic body

"For $40, this is absolutely worth it if you're willing to put in some technical effort. Mine was labeled "DOES NOT SHOOT", but it turns out the motor was screwed on too tightly and the air seal wasn't installed correctly. There were a few aesthetic issues, such as a loose buffer tube (whoever used it didn't know how to tighten the screw inside and tried to glue it to the receiver), a dented receiver, and a semi-functional delta ring (easily replaced). However, after tinkering with the gearbox and fixing the issues, I ended up with a fully functional EBB M4, all for $30 and some time. These are also great for props, spare parts, and experimental tinkering/designing. I gave it a custom paint job and made it my backup rifle, definitely worth its price.

"Purchased on about 9/21/16. Received an Ignite Black Ops Airsoft M4 Electic Blowback Airsoft AEG, which is probably on the lowest end of the quality spectrum while still having a metal gearbox. One or two minor pieces were broken off the receiver but the gun was firing out of the box, though its fps was very poor (probably ~100-200). The grease in the gearbox was pretty bad so I cleaned and reshimmed it. I also replaced the stock O-ring on the piston head with one that was a bit larger and re-greased the piston, cylinder, etc. The gun fired decently after this - nice and quiet (compared to my CYMA metal AK) - but I have yet to confirm its accuracy and exit velocity. It'll probably last a while but isn't useful for much more than a backup gun.

My major disappointment was that I just noticed that this gun was moved from this boneyard listing to a separate boneyard listing for $10 cheaper, so this review really belongs under that item but this was technically the item I purchased... Anyways hopefully you'll get something a bit nicer if you purchase an item from this listing.

"Bought one for parts or to fix up if simple.
The gun would only shoot a BB like 10 feet so I knew it was internal with the gear box. And when it was shooting is sounded horrible.
The piston was used so much all of the rubber on it was off and in the cylinder and the teeth were almost gone. Lucky for me I have tons of parts And put in a new one and that fixed the issue.
The other bone yard m4 I got was an Elite Force and that was a broken gear box near the quick change spring and guide rod. SO that is no ez fix. To be honest this isnt horrible for 40 bucks but the gun itself is BAD...Its plastic just above nurf guns but Nothing like a G&G or any quality M4 plastic. The gun shoots a lower FPS too. My finished gun shot 300 310 fps with a .20g bb so its not really even good enough for long range engagements or field play. This would be a good thing to fix if you are new to Tech type of work and want to leave your working gear alone. However keep in mind you get what you pay for and 40 bucks you get that. Give this to a buddy to use for the day as a Loner type of gun after you fix it.

"My gun came to me in about 8 pieces and missing all accessories. It was clearly used and abused. A couple hours of work and borrowing parts and it fires OK. It's an OK $30 back up gun I guess.
