It keeps the piston and spring precisely aligned, ensuring more reliable piston engagement when cocking the rifle. The brass construction also allows the use of stronger upgrade springs that are not compatible with the original plastic ring.

AirsoftPro AEG progressive spring (SiCr) M170 is an upgrade part designed to increase the performance of electric airsoft guns and manual SVD rifles. It is made from silicon-chromium alloy valve spring wire (SiCr), which is also used for highly stressed industrial springs. Thanks to its progressive winding, it provides smoother gearbox operation.
The AirsoftPro SVD spring centering ring replaces the original part used in manual A&K SVD sniper rifles. Its purpose is to keep both the spring and piston aligned during cocking, helping to ensure reliable piston engagement. The original plastic ring limits spring compatibility to approximately M150, as stronger springs typically have a smaller inner diameter. The AirsoftPro brass ring solves this issue and allows the use of more powerful upgrade springs without this limitation.
Keeps the piston and spring on the same axis, helping to ensure proper operation of the mechanism during cocking.
Allows the use of upgrade springs with a smaller inner diameter that cannot be used with the original ring.
Durable brass provides long service life and precise guidance of moving parts.
Helps prevent the piston from lifting during cocking, which could otherwise lead to unreliable sear engagement or accidental firing.
Designed as a direct replacement for the original centering ring in manual A&K SVD sniper rifles.
