LCT Complete Gearbox w/ Electric Blowback and Recoil Kit for AK Series Airsoft AEG
(Model: Long Bolt)

"I know there are pros and cons to EBB and I generally disable any EBB guns I get since they’re usually pathetic and the slight cons always outweigh the performance I typically focus on.
The G&G pneumatic is the least stressful but it’s a complete joke. I didn’t like the measly sounds that came clanking from them and I figured the non-steel charging handles had a slightly increased risk of snapping after a lot of use.
Some of the Ares ones were so-so. Not really fun but at least what I would generally consider as truly EBB.
The only one I was happy with was my BO Manufacture. MP40 (which should be SRC OEM).

Once I saw LCT’s video announcing these, I wanted one. Even with any cons, this looked like a fun EBB. I finally bought this gearbox for my LCT and I gotta say it is shocking how fun it is. I don’t even need to go play airsoft with it; shooting it in the house and feeling it and hearing it are impressive in itself. If you like GBB, this is your best bet. Boy, do I see why people say to loctite everything.

So about this; the listing currently shows it with a T2 torque motor but it comes with a T1. Converted for 11.1v, the T1 is approx. 30k and the T2 is approx. 36k. I am using an 11.1v for an outdoor setup and the ROF is nice. With a 7.4v, it’s far too slow.

After counting the teeth, the gears appear to be 31.9:1. Some LCT gears seem to do fine, others seem to rip apart, so we’ll see how long these last. If I need to swap, I may try 18s with a ZCI motor. The piston is all metal, unsurprisingly. Aluminum piston head and poly cylinder head. Their usual POM tappet. Standard o-ring nozzle. The EBBs have smaller bushings compared to their 9mm bearings. They were very close to a perfect shim job on mine.

Seeing how much… everything… shakes, I swapped my hop up to a Combat Union one which seems to keep in place a bit better. I noticed the arm shook a bit too much for my liking in the stock one. The only other thing I swapped was an ETU in place of the standard trigger contacts. Cycle completion didn’t quite seem to be as much of an issue as I thought but you could easily encounter the weird semi-auto hangup you occasionally see with V3s. I also may be glad it’s on an LCT. The entire thing being made of steel helps with the overall feel.

There are no institutions, but they do have a video. This may sound dumb until you see a random black piece in there and have zero clue on what it’s for. It is supposed to get shoved up under the rear sight leaf spring. I imagine this is for protecting the mock bolt from scratching on the metal edges there.

I cannot fathom wiring this to the front as some models have… this seems to be very specifically wired up and designed to be wired to the stock, which I like since it allows a good selection of batteries.

Beautiful recoil. Decent parts. Comes with everything you need. I am very pleased with it. If you believe the pros outweigh the cons with EBB (and want a fun EBB at that), then I can highly recommend this.

And again…. Loctite everything.
