[180] 9mm AR drop-in FRT-ready bolt weight and XP firing pin spring. NO GRINDING! https://greyhive.com/videos/watch/dd4cdf2a-f154-4b9a-a151-6a9f6d5da8de https://rumble.com/v7gknza-180-drop-in-pre-trimmed-bolt-weight-and-xp-firing-pin-spring-for-9mm-ar.-no.html MSRX-USA is making 2.7oz. pre-trimmed hardcast cylindrical bolt weights that fit many 9mm AR bolts. No more cutting or trimming the 9mm AR bolt weight for certain triggers! They also stock the 2x firing pin springs individually to prevent dead trigger/light strikes which is a common failure with 9mm AR's using certain triggers. Weights are available as pre-drilled or solid if you want to drill it yourself. I have no financial arrangements with any of the companies mentioned in this video.
