Increasing the "dwell time" in mechanically delayed blowback rifles may help mitigate pressure-related issues, but this solution faces significant challenges. The risk of case head exposure or rupture due to unsupported rearward movement of the bolt, and potential mechanical wear on components like delaying rollers or levers, may compromise safety and longevity of the firearm. Adding a two-step delay also increases design complexity, potentially introducing new failure points. Thus, while intriguing, this solution requires careful consideration, design, testing, and should only be undertaken by qualified professionals. - ChatGPT
