Strike Industries flat wire spring in carbine length drops into a milspec carbine tube without any modification. Less spring twang felt through the stock compared to round wire. Cycles cleanly. Solid quiet upgrade for carbine builds.
Strike Industries flat wire buffer spring in carbine length is meaningfully quieter than a music wire spring. Less spring twang felt through the stock. Cycles cleanly. Dimensions match milspec. Worth the upgrade for any carbine.
Strike Industries flat wire buffer spring is the upgrade I didnt know I needed. Cycle is quieter, no spring twang felt through the stock. Dimensions match milspec for any carbine extension. Drop in fitment. Worth the small upgrade cost.
flat wire spring for AR carbine, dropped right into a carbine extension with no fitting. impulse is quieter than a standard carbine spring, no spring twang. action feels smoother on charge stroke
