The weight of the spring can vary on design and intended purpose. Strike Industries does not provide the weight of their AR Pistol Flat Wire Spring. It is specifically designed for pistol length buffer tubes. The weight of your buffer will greatly determine reliability and functionality compared to the spring. Email us at Techsales@opticsplanet.com for more information.
The Strike Industries AR Pistol Flat Wire Spring will work with the Strike Industries H3 Buffer in an AR Pistol.
This is compatible with any AR system with a Pistol Length Buffer System. The SBA3 operates off a carbine buffer system, so the carbine length spring should be a better fit.
