Frequently Asked Questions
Is this recoil spring compatible with my AR-15 pistol or SBR with a carbine buffer tube?
Yes — as long as your AR-15 pistol or short-barreled rifle (SBR) uses a standard carbine-length buffer tube, this spring is compatible. It is designed to work with any mil-spec carbine buffer system and pairs with a standard carbine buffer weight. Always confirm your buffer tube is carbine-length rather than rifle-length before ordering.
How often should I replace my AR-15 recoil spring?
Most manufacturers recommend inspecting your recoil spring every 2,500–5,000 rounds and replacing it every 10,000–15,000 rounds, or sooner if you notice signs of wear, inconsistent cycling, or failure to return to battery. Keeping a quality replacement like this LBE spring on hand ensures you can swap it out quickly and get back to shooting without downtime.
Will this spring work with a standard mil-spec buffer, or do I need a specific buffer weight?
This carbine-length recoil spring is designed to pair with a standard mil-spec carbine buffer (approximately 3 oz). It will also function with heavier buffers such as H1, H2, or H3 variants, which can help reduce felt recoil or tame overgassed rifles. The spring itself is the standard-rate replacement, so tuning for specific loads may involve adjusting the buffer weight rather than the spring.
