A little more specialized than just dumping superlube into every crack and crevice, if you ask me. Both greases work quite well. They taste and smell mediocre, but that's ok.
The o-ring grease does a great job, specially paired with some viton 60A rubber, it's hard to beat. slippery and slidy wonderfulness for the gearbox, those italians have it figured out. well, maybe not the calcium soap bit, that makes me think I'm machining my own gears or bushings or something, however; I have yet to crack open a gearbox running this grease to find the gears are trying to eat eachother (also a product of bad shimming or alignment problems but you get the drift, gear surfaces are pretty clean)
Thus recommend to me by Louis as I didn't know what the proper lubricant would be to use when reassembling my STG44. Seems to be the right stuff. Doing business with Brill Amory was truly a joy. Now my gun went from 317 fps to 389 fps thanks to their recommendations. Thanks Louis!
After talking with Louis I replaced my stock spring guide with thus one. Omg! Add this part along with other parts Louis recommended it increased the FPS from 317 to 389.
Thanks Louis for all your help and patience!
I highly recommend this online store for all your upgrade needs. Very professional, knowledgeable, courteous, and fast shipping.
Thanks again!
I can't review this product as I did not use them after all. After talking with Louis I ended up replacing my spring guide with an up grade and therefore didn't need to use these.
Installed this part with other parts recommended by Brill support. I'm so amazed at the difference it all made for my STG44.
Went from around 317fps stock to well over 389fps. Thank you Louis for all your help. You are the best.
Sincerely.
10/10 brill is the best
I had 3 different aegs experiencing midcap syndrome. Vfc scar h and Jg g36 whose midcaps were too strong filled over 100 rounds, and a Ics sg552 whose midcaps only hold 50 rounds, and would only work if filled up to about 25. I installed this spring in all 3 of those guns, and all of them were able to handle their filled midcaps. As a result the tappet plate broke on the scar, which I replaced with a spare guarder v2 one. Make sure to glue your delayer chips otherwise they will come off due to the extra spring force. This also happened on the scar and I didnt notice until I opened it again to replace the tappet plate.
If you don’t have one of these for your vector, you must hate yourself. It is the the FIRST upgrade you should be getting for this replica
I ordered goods from Europe and everything was exceptional. Packaging, speed and excellent customer support.
Seems good so far but only time will tell as to how well it holds up.
Super fast shipping and a great upgrade
definitely worth the money and brings up your airsoft guns performance over stock factory buckings. good material quality and great price. will definitely buy more in the future.
Great seller, great product. Will do buisness again. Thanks
I threw it into a Prometheus/Laylax gearbox and the piston head had a good seal in an ASG cylinder. The particular piston I received was labeled a "14 tooth piston" but the it was more like a 14.5. The piston head isn't threadlocked and the rack isn't glued. It also included a bearing behind the piston head.
Although it was a tight fit, it gave me a good seal when paired up with an ASG cylinder and a Double Bell Alu nozzle (it worked with a Slong one too). It didn't fit into my Maxx cylinder, maybe you can make it work, but you risk damaging the oring.

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.
