You think HAO will just replace the higher torque of spring for our Advanced Cylinder?
Nein, the answer is no. We enhanced the major parts inside the cylinder , which you could see by the following pictures; Rack, Hybrid Bumper, detent spring and the SWP-B Spring for the best performance. Rack Since our M150, M165+ still in developing , we've enhanced the rack to the best to fight with future monster springs. But, It's quite tricky which we couldn't just use the hardest material but have to keep the same hardness and little bit weaker than the gears from your gearbox.
SKD11 tool steel is the solution, we've used the same material to lathed Window breaker to equip Taiwanese law enforcement before. After heat treated to 50HRC, that's 100% guarantee good to go with high torque springs.
(*For the best ROF and performance , M90-M110 cylinders use S45C Carbon Steel with 40HRC)
Hybrid Enhanced Bumper
That's the most important part to meet the higher velocity builds, the balance of recoil and impact. Yes, SYSTEMA's OEM use the same design to "endure" the great impact of higher tier of spring (M130+), but they only made it to stand still barely. Since HAO's HQ is a valve company , we undertake the sealing experience , We 've tried every plastic like, NBR like , difference height of collars and combinations to match your M130 Cylinder not only a spiting flamethrower but the game changer with the most stable FPS cylinder in the market.
(*For the best ROF and performance , M90-M110 cylinders use full NBR 90 HRC bumper)
The key pillar of the cylinder to fight with forces, since HAO's Advanced Cylinder are using bearing thrust system , we have little space left then have to re-design & enhanced the detent spring to the limit; the strongest detent spring ever in the market which would not only make your Cylinder tight like virgin but also solve out your wobbly receivers.
( Bearing thrust system is all standard equipment on all HAO's Advanced Cylinder)
(The strongest detent spring ever in the market, the solution of your wobbly receiver) SWP-B Spring
As a ordinary Subsidiary of a valve company, we have tons of springs in the factory. Here is the best consequence ; SWP-B (Cold-drawn Steel Wire for Mechanical Spring). I don't have extra information for you, but it is the best spring.
Enjoy your HAO's Advanced Cylinder (M130) !
