These little piston heads are inexpensive but by no means *cheap*. They are very strong; their o-ring seals the best I've experienced so far. Their diameter is a bit wider than a lot of piston heads so check fit in your cylinder as cylinder diameter does vary slightly from make to make. The one caveat is that it is *very* light. That's the whole point of this piston head. If you want to use it in a regular every day build, it is so light your piston will not be heavy enough to use anything beyond .28s or so in my testing, your build will of course vary. I was able to use .32s in my builds by not using the polymer spacer that comes with it but adding a standard spring bearing set you'd install with any other piston, but .32s only gained a small amount of energy with that.
I'm honestly struggling to say anything more, and that's a good thing. It's a solid, inexpensive cylinder head that you can make work if you want an inexpensive cylinder head for a build. I'd personally recommend it for lighter weight ammo builds.
Wonderful customer service and pricing for these durable gearboxes! This new 2025 gearbox seems to have the bevel gear sit a little lower than the usual gearboxes from CYMA and VFC, so I’d recommend purchasing the Airsoft mutation grip shims as well with this gearbox. Alignment is a little off when installing (horizontal alignment is off), but I hope Brill Armory stocks the Retro Arms lateral adjuster for this gearbox in the future. All in all wonderful value and quality! This is my #1 go to store for high end AEG components!
I've had bad luck getting Maple Leaf bucking to feed with different combos of nubs, barrels, hop units and even AEGs but never an issue at all with 4UAD buckings. I use them in all my AEGs and they perform amazingly.
Just a few features I want to mention that the description missed:
+++Non-Magnetic:
The Ares/LCT Super High Torque motors this 'slim' motor replaces have 'extremely' strong magnets in them that are constantly grabbing every screw, washer and every tiny spec of ferrous material in a four inch radius. The motors can snap to the receiver of the rifle with incredible strength, potentially damaging the sheathing of the motor wires when doing so. This Solink brushless motor is completely non-magnetic. Very easy to work with in this regard.
+++Anti-Reversal Latch Removal:
This makes the gearbox so much easier to assemble/disassemble. I couldn't tell if it made it any quieter, and it's possible it eliminates potential shimming issues with the bevel gear. It's very nice to have just for ease of assembly though.
+++More Fine-tuned Motor Height Adjustment:
The threaded collar on this unit that screws to the gearbox has much finer threads than the ones on the Ares/LCT branded models, which are quite coarse. This can lead to difficulty getting the pinion/bevel gears shimmed right with the Ares/LCT offerings. The engagement steps are much finer with the Solink.
+++Better Pinion Gear:
The pinion gear on the Ares Super High Torque motor is a strange shape, much narrower than all the others I've used. It does not mesh well with the gearsets I've tried to use it with, and I've needed to replace it on both guns I've installed one on. Can't remember if the LCT 'slim' motor also had this issue. But the Solink motor comes with a normal pinion gear that seems to work fine out of the box.
+++Works great with the Perun Hybrid V3
No issues!
Performance: Bought this to see how fast/spammy I could get on semi-auto with a rifle already upgraded with high-speed gears, 14.8v (or 11.1v) battery, and an ETU. Mainly trying to see if I could match the semi ROF of HPA-users. It's extremely fast, but I'm not sure how much more so than the already quite powerful motors that come with the slim grips anyway.
If you want extreme torque in semi, or extreme speed in full-auto, I'm sure this can provide either. But as for spamming the trigger at semi-only events in a normal rifleman role, I'm not sure it's worth replacing the slim extreme high-torque motor.
My complaints:
---It's difficult to attach to some gearboxes. Attempting to mate the Solink with a Bullgear GB shell took a while, as the fit was extremely tight. This is an issue with the Ares/LCT motors as well.
---No source for just the slim grip. You gotta buy the inferior Ares/LCT motor+grip combo and then throw motor away. LCT has more colors and only one screw hole at the bottom like a real AK, the Ares has two screw holes for some reason (although you can fill the back one with black epoxy and sand flat.)
Battery performance???
Brushless motors are supposed to be far more battery efficient... Not enough experience yet to tell.
Slim grip:
As an aside, I love the slim grips that Ares first debuted for the AK, a traditional airsoft AEG pistol grip feels like a brick by comparison. If you're used to shooting a real AK you'll feel right at home. Absolutely worth picking up a slim grip + motor combo instead of a normal high-torque motor if you're doing a less extreme build. Keep in mind the above limitations though.
awesome product and great customer service
It seems like the quality of Lonex parts has taken a nosedive since COVID, but this piston is still top notch. The added weight is a huge bonus when trying to reduce joule loss with heavy bbs.
Fixed my premature engagement issue and fps is very consistent every cycle. A great spring!
I decided to give these a try on a SHS cylinder head to correct AOE. The pads are very well made, and the 3m adhesive pads are a nice alternative to using super glue.
Placed into a Lambda MK48 this bucking resolved some air leak issues dramatically increasing joule output. The lips of this bucking are quite frankly the only properly designed ones on the market (read - THICK). Ive used maple leafs and PDI W-Holds and have had airseal issues or the lips being pinched resulting in a compression jam. No such problem with these.
Easy to install like the has more programming options for precocking and trigger sensitivity. Perfect for speedsofters and nerds like me who love a snappy trigger.
Ich kaufe nur FPS Cylinder
Excellent project!...... Brilliant Armory is an awesome company!. Will do more business in the future.
I selected this cinder head for its built un AOE pad thats tapered for better air flow. My only concern is the front bumper design. The side holes are slotted to prevent the gearbox pins from sheering, but the bumper itself is very hard and wouldnt fit in my VFC unless I sand it down ( which I dont want to do). Its a shame because I really wanted to use this.
Thanks for your review. These Cylinder Heads can function perfectly even without the front padding. If the front of the Cylinder Head still makes contact with the front of the gearbox, it will work.
Will definitely order from Brill Armory again 100% my order came 2 days from expected date and prices are very good.
It’s too tight when putting together. Would return it if I could if I didn’t already sand/grind interlocking tabs
We're sorry for any inconvenience. If there are any issues, you can always reach out to us or the manufacturer before doing modifications/fitting. If you're still having problems with the body, we are happy to assist.
Solid! No warp or wave, comes with a dual o-ring aluminum cylinder head, aluminum o-ring nozzle (21.25mm), ribbed stainless cylinder, full metal rack piston, aluminum piston head, and a M115ish spring. Gears are 16:1 steel with what looks like a thin paint, so they are likely PMI but I can't be sure. The tappet spring seems normal strength or better, and the tappet is fiber reinforced polycarbonate - no replacing needed! The gearbox itself is microswitch type, so fair warning - you can't use internal ETU's with this gun! You'll need an external one like a Gate Warfet. No corner breaks up from the factory either, you'll have to relief cut the cylinder corners yourself.
All in all? Solid as hell. A great gearbox to build on if you're using an external mosfet setup. It comes with enough awesome parts out of the box that you won't have to change much at all.
I bought these along side a retro arms gearbox and I can say the fittment is way too tight. I cannot fit these into the gearbox they are made for unless I go completly heavy on hammering. To the point where it's damaging the bushings/ gearbox. That's even after freezing the bushings to try to make them contract. The being said I could only get one bushign to properly fit in. Unless you have a press I would never suggest these bushings. I am going to continue try to fit these but suggest anyone looking into these to consider a another good bushing in combination with JB weld. Also please support Brill as there a great store to by from in my experience.
Sorry for the trouble. If you'd like the bushings to be press-fitted by us, please let us know.
First owned AEG, have played with my brothers Specna Edge 1.0 m4 platforms a few time and liked it, always thought it felt like a good performer for the money. With the release of the Prime series, and not wanting to have to upgrade anything immediately, the slight price increase from the Edge 2.0 to the Prime seemed like good value. Brill was one of the only retailers to have stock.
I have shot probably 100 bbs through it so far, went with the Titan LiPo 11.1 as Specnas own manual suggests for the HAL ETU. Set semi to just 20% trigger point. Full to 3 round burst. Precocking off and active brake off. Trigger reminds me of the 3.5lb trigger in my actual builds.
Gun feels very snappy and with a few red dot adjustments was a tack driver. Have not messed with hop up adjustments yet or played outside, so cannot give a more thorough review on that.
Hopeful it performs hassle-free like my brothers edge has for 2 years. Time will tell.
