Guarder is a Taiwanese brand that makes strong Gearbox parts with good precision and quality control. Because of this, Guarder has a solid reputation as a parts manufacturer. Brill Armory is proud to add a variety of Guarder products to our inventory.

Guarder springs are made of Oil Quenched/Tempered Si-Cr Alloy Steel Wire and are generally considered to be some of the most consistent springs on the market. These springs are rated to their actual power and are not mislabeled like some ACM springs on the market.

Please note that the final AEG power output is dependent on a ton of factors, and as such Brill Armory cannot guarantee a certain FPS. Some factors include compression, inner barrel length, cylinder type, inner barrel diameter, BB's used, bucking/hop-up parts used, and tappet timing.

Good spring - shooting a little hot

I bought this spring, aiming for 1.6J output. Got my gearbox and compression components dialed in. Chrono'd @ 1.68-1.72J, so it looks like I'll be needing an M110 or M115. Previous reviews stated lower ratings, which wasn't the case for me. Good spring, but I'd recommend buying your target spring and one lower just in case you get in a situation like mine. I really like the packaging they use because you can store them and know exactly what's inside.

Underpowered

I dont know what's wrong with gaurder, but over the last year these springs have been consistently underpowered, performing like sp110's instead of 120's. This is probably my 5th or 6th spring order that's come in underpowered. They are still very consistent, but dont expect 120m/s with these, theyre closer to 110m/s.

Sorry for the inconvenience. We can measure the spring's power on our end and provide a replacement if needed.

Additionally, we can send free spring guide spacers if you require them. Please email us if you'd like the spacers and/or replacement springs.

sp-120

Good spring, doesn't bind, built well, just a tad bit under powered but I would buy guarder springs again.

This is one of the best springs on the market, however the last batch of this springs are wrongly packed, they are SP110 inside of the SP120 package; what is completely wrong in terms of you don't get what you really order. The thickness of the SP120 is around 1.5mm and the SP110 is around 1.40mm, and this is happened on Evike and Brill stores a like. I hope Guarder recheck their mistake and provides with the correct product.

Guarder makes the best AEG springs on the market, hands down! They never lose spring tension and are EXTREMELY efficient. No extra amp draw in comparison to any competitor and much better fps! This spring, with decent airseal, can easily hit 410+ fps. Also, its efficiency allows it to maintain fps output as much as possible. I recently used this spring and ss'd 2 teeth off of the sector and got 385-390 fps. 10/10 best springs
