GET THIS MOTOR! The motor shipped within 5 minutes of me ordering it and arrived in 3 days. It has great torque and I havent had any issues.
Very high cnc quality on this, its also a blessing to be able to use vsr spec bucking and barrels. The only down side to thus product is its very difficult to adjust the hop through the barrel extension on a ghk. Otherwise 10/10
This shell fits everything I have thrown it at without issues. Personally i prefer them to higher end brands that are CNC’d. They pair well with TM spec hops and standard 21.4mm nozzle length. They also pair well with just about anything else. I have not had any issues fitting these into G&P, CYMA, VFC, Classic Army, JG, ASG, and Krytac. I use these shells as my go-to for custom builds in my professional practice to reduce issues i’d need to bill my customer for.
Some brands are a bit tighter than others but I’ve yet to find a TM spec brand that wouldn’t accept this gearbox. Sometimes the back edge is a little tight and needs some encouragement, but i’m not sure what compatibility issues anyone else is describing i’ve experienced none over two dozen of these shells. BUY!
Great product works very well
Rather pricey for what amounts to simply being a 3D printed piece of plastic. I appreciate the the thought that's gone into this design. However I do feel its price is justified by the rarity of such an item and the convenience it provides. So I am actually quite happy with my purchase and was very impressed with its super speedy delivery.
Absolute amazing piston, the racks are very strong, the rails are continuous, AOE corrected rack already, wider rack for higher shimmed sector gears, piston body is tough.
Just like other A.M products, these pistons are designed by airsoft techs and hit all the marks needed for those custom builds while LASTING.

These are great Airsoft spring shims/spacers. Having a variety of Inner Diameter sizes is very helpful since all spring guides are not the same size. I only wish they only made them in 1mm, 2mm & 3mm thickness. The current ones are 2.5mm thick which limits your ability to fine tune.
Motor is awesome, compatible with my CYMAxEMG GRY rifle with the Eshooter Kestrel v2 Basic ETU. Shipping was great, product arrived earlier than expected.
Brill Armory is a top notch online airsoft store and their customer service is excellent.
The Airsoft Mutation Spacers I bought are very good but I wish they would offer even thinner and wider inner diameter sizes. The 11mm ID was unfortunately still a little too small for one of my spring guides but fit just fine on others. Also thinner spacers would allow even more fine tuning.
The guys over here at Brill are amazing, and the product they sell are even better. I put this in my aeg and instantly pumped from 380 to 425 consistent. Even in fulll auto it is extremely consistent.
I installed this into a personal build to replace a stock brass barrel that corroded beyond restoration and it works very well. As with the dozens of ZCI barrels I've used and installed for people over the years, it's cheap in price but it's high quality. The finish is nice, the crowning from the factory is well done, and it's hard to spot any imperfections in the barrel with the naked eye.
For reference, I installed a G&G green bucking (which has a snug fit around the outer diameter of the barrel) an r-hop patch made out of 80 shore tubing, with 6mm ID and 8mm OD. That seems to be the perfect fit. The build I have it installed in does about 1.1 joules with 0.2g BBs and creeps to about 1.3 joules with .32g BBs. The heavier BBs do very well given the good finish and consistency of the inner diameter surface.
Upon receiving my barrel, I inspected it and noticed a tiny bit of dirt and debris around the hop up window which I assume is from the factory. That's not an issue at all as you should definitely clean your barrel both upon receiving it and with regular maintenance. It's just something to be aware of.
Most of the time, an upgrade barrel is not necessary. But when you need one like I did, you might as well get something like ZCI barrels because they are a phenomenal value.
Looks nice, feels nice. Works with Cyma SVU, arguably easier to use than the Cyma oem mags.
I’m sending emails out to return products and no one answers.
You just emailed us minutes ago, and our response to you was included directly below in the same email thread.
Box mag was junk. Installed this, which required wiring the battery connector from the old insert. Increases ammo capacity and feeds like a dream. 30 rps. PKM goes brrrrtttt. Highly recommend. I was looking into Bullgear, but seemed sketchy with the Paypal process and ordering from Russia.
Works beautifully in my PKM build with 16:1 gears. Pulling an M130 spring. 1.5 joules @ 30 rps
Just what my gun ordered made set up of gearset and etu 1 time, and changing piston assembly so easy.
I bought 13:1 helical gears from you guys before and they had a nub and protection with clear grease on them, these how ever came in no nubs and they where dirty/ staining my finger unclean gears are these returned or used?? that’s not cool imo
All the parts we sell are brand new unless stated otherwise in the product title. Please email us with images of the gears so we can look into this.
Is there any indication that the gears were previously used, aside from the axle covers and machining grease? Not all gears will have the protective axle covers intact from the factory. Gears that have been installed and operated in a gearbox should show clear wear marks.
