The Chrome Silica spring is not made of plastic. This is a common spring for buffers in the AR platform. Owing to its high tensile strength and resilience to high temperatures, chrome silicon is the first choice of material when it comes to fabricating springs. Chrome Silicon springs are cold drawn and heat treated before fabricating. These springs are widely used for shock loads and/or moderately elevated temperatures.
