Installed two of these. Just finished a 13:1 400 fps Perun build and it is super snappy. It does however get a little warm, and I needed to apply a level of AB to stop overspin. Hopefully the AB won’t kill it, because it’s a total PITA to remove the gearbox from the Elite Force hk416 competition in order to short stroke it.
I also installed one in a customer Krytac with stock 18:1 gears, and it still has a very respectable amount of snappiness. I would highly recommend this, or the 28k version with 18:1 gears for a very efficient and still spicy Milsim build, and for short stroked high speed gear builds
Needs a new spring guide, the one it comes with isnt the best. Probably should get a retro arms steel screw set as well cuz there are only grub screws for the tappet spring post.
Its a strong piston head that can handle my full 19t stroke MS170. Mild issue, the Oring its shipped with is kinda bad, replace it.
They are pretty fast, and i dont have any power loss with that, so i have two benefits now, hightfully recomemded
Running this with an SP140 with spacers putting out 1.3J but I have tested it with an SP160 with no issues. If you want to make your gearbox as quiet as possible the helical bevel and pinion is a must but getting a whole DSG gearset for $40 with the helical bevel and pinion is a deal. Shims like any other gearset, just sounds so much better. If you want to take the next step in making your AEG as quiet as possible, this is that. Reduces gear noise to almost nothing.
I have run a couple of these. One in a 1.3J 18:1 DSG. Produces ~40 RPS. At 1.2J semi trigger response was 26-27 ms, but the bump up to 1.3J raised it to 28-30 ms. These motors do have limits but are stellar for the price. I have another in a 13:1 SSG. At 1.45J with 16t it put out a measly 24 RPS. I swapped to a 12t sector and added spacers to bump up the power. Much better results, 27 RPS and no need for any precocking anymore.
I ran it in an SSG at 1.45J with a custom M Nub. Produced stellar groupings and excellent range with 0.32s. The lips are a little shorter than Mapleleafs so less fitment and jamming issues. Note: VERY sensitive to being slightly skewed. A few degrees of misalignment caused the BBs to noticeably curve off to one side past 100 feet. Realigned it and then it shot straight.
I recently purchased this gearbox, I was in a need for an ssg for m4 Bodys. It’s a very simple install and the parts list seemed decent. I did play outside with it at my local field
I will admit that the velocity of the spring is very slow and not listed in the description but listed in the comments sections BEWARE!! took a long time for my bb to travel. Consider in upgrading at some point
Sorry for the inconveninece. The power output shouldn't be too low. The gears in this gearbox are short stroked by 4 teeth, so there may be undervoluming when using replicas with longer barrels. Also, be sure that the Air Nozzle is sealing properly with the Hop-Up chamber. Please email us with the power output you're getting and the barrel length. We'll figure it out!
ive used plenty of other GBB buckings before, and this one has to offer the absolute best price to performance that I have experienced.
I used this PDI Palsonite 113mm barrel all my 5.1 hi capa and 1911 pistols during indoor competition.
Better good ole bandaid
Works as stated it’s a good cylinder good consistency
Received the item very good quality
I was so surprised how fast my order came and they kept me informed and did I mention this was my first order with Brill. If the 2 I ordered these guns for need anything else I will have them order from here
My gun was shimmed well from the factory but still had a chirp with each semi-auto round. These 13:1 helical gear set was the solution. These are full helical, not just the spur and sector gears, but the pinion and bevel gear also. Better trigger response and much quieter operation. They seem high quality as well.
Perfect for new hi capa 5.1 project with just 2mm longer than the original barrel
These nozzles are actually true to size where every other nozzles iv measured is never what they claim it to be.
PDI Palsonite 138mm is a perfect length on my hi capa 4.3 with compensator. And the PDI Palsonite barrel is the most accurate in the planet right now…
These Guarder springs are no joke!! I have both the SP160 & SP170. My 8T DSG P90 shoots 1.77J using the AP160 lols. FPS variation is around+/- 4 FPS
1.77j is insane for an 8T DSG! Good work!
Picked up this rifle to be my new AEG at events. Just attended operation flamingo and it ran beautifully the whole event. The gun was shooting very hot out of the box at 450fps I think I received 2 m130 springs because we when I swapped down to the m110 it did nothing. I ended up cutting two coils off and it was perfect. The quick change spring system is awesome. The flat hop setup lifts .32 no problem out of the box. The motor never got hot. Overall this rifle is a workhorse. It’s a lot of bang for your buck and I would highly recommend it.
Thanks for sharing your experience! We're thrilled to hear that the replica performed so well during your event. We completely agree that these replicas offer fantastic value, which is exactly why we carry them. While we're happy with the QSC feature, we've contacted the manufacturer regarding the FPS out of the box.
