From the manufacturer

Designed for the Maxim Defense CQB Stock, the Silent Captured Springs are Maxim exclusives made by JP Rifles. By eliminating the friction found in standard buffer setups, the JP Silent Captured Spring also allows for smoother action resulting in less sound as the bolt cycles. Available in a Standard weight, a Heavy weight for select fire platforms, and a 9mm specific version.
