The XTC Carbine AEG is the newest version rifle from Modify Airsoft. Modify Airsoft has been well known in the airsoft market for providing high quality internal upgrade parts and accessories for a wide array of rifles. With all those parts combined, they have come out with their own complete airsoft gun. The newest version now come with an AOE kit for better gear alignment. Modify has revamped the hop up arm to provide better performance and precision with .30g BBs. The magazine can now insert into the AEG easier than before without much of struggle at all. The Modify XTC Carbine features a billet style aluminum upper and lower receiver as well as a keymod front rail system made out of aluminum as well for overall durability without increasing the overall weight of the rifle. The left and right side of the gun run an ambidextrous fire selector but with a twist. The selector only needs to turn 45 degrees to switch from semi to full auto instead of the traditional 90 degree turn. The trigger contains a straight trigger commonly found in competition rifles for a more pleasing aesthetic appearance and function for the shooter. The upper receiver consists a functional charging handle and bolt catch to allow ease of use when adjusting the hop up.

Internally, this rifle features a very unique gearbox design. The quick change spring system can be accessed through the buffer tube with the use of an extended 4mm hex tool. The piston features Modify's white ultra piston with the second to last tooth removed and half steel teeth rack for extended durability. Compression components include Modify's upgraded aluminum cylinder and cylinder head with double o-ring. In conjunction with these the air nozzle has an o-ring to maintain maximum air seal. With all these parts combined, the gun's velocity is much more consistent and no longer need to upgrade the gun even further right out of the box. The gears feature the common version 2 gear set but for only the bevel and sector. The spur consists of a design similar to a version 7 gear set to obtain a little higher rate of fire. 8mm Ball Bearings allow for a smoother rotation as the gun operates. Overall, the Modify XTC Carbine shoots amazingly with heavier BBs like .30g and is designed to be upgraded already right out of the box for performance and durability.

Product Information:
Was looking forward to this gun very much. I did extensive research and had believed that this would be the very best bang for my buck, especially coming from the same price point as the Krytac SPR.

However, don't be fooled. Many pro-airsoft techs will tell you, Modify makes great products in theory, but their execution always ends up worse than one would hope.

In this case, the Piston broke in less than 500 shots. How? I wish I could tell you. It's sad too, because the compression was nearly perfect right out of the factory.

after replacing the piston with one with a full metal rack, I reassembled the gun to find that the internal mosfet's breaking system had been fried. The gun would not stop firing, with or with pressing anything.

- Beautiful, sleek, full-metal design
- no wobble on stock
- decent field sights
- Keymod rail system
- Quickest change spring system on the market as far as I can tell.

- Piston breaks in 500 shots or less
- Integrated mosfet stops working in the same amount of time
- v7 gears in a v2 gear box (apparently to achieve higher rps)
- 350 bucks down the drain.

Product Information:
My buddy purchased this gun a few months ago and oh boy is this thing a trip. If I could give zero stars I would, but this thing has a very good external build quality. Something went wrong with the wiring the first time he took it to a field. He ended up spending the rest of the day with the local tech. A couple weeks later the piston broke and again, he spent the rest of the day with the tech because apparently that wasn't the only thing wrong. Now his gun is in pieces because it just stopped firing. His selector switch, and the bolt release broke and we put it back together and couldn't find a good spot for the motor height and it stopped firing again. The motor, by the way, is seriously the hardest thing to put in and it makes no sense. We tried everything and it still does not function at all.

Looks good
Good build quality
In theory, it should be very nice

Honestly everything that could go wrong has went wrong
Forgot to say that the hop up is trash. Hops up no matter where it is adjusted

great gun
