Ar-15 Front Sight Spring

The AR-15 Front Sight Spring manufactured by Sons of Liberty Gun Works is a precision replacement component engineered for shooters and tactical professionals who demand reliability in their rifle platforms. This spring is a critical element of the front sight assembly, responsible for maintaining proper tension and ensuring consistent sight performance under field conditions. Whether you're running a duty rifle, competition setup, or defensive platform, a functioning front sight spring is non-negotiable for safe and accurate operation.

The front sight spring works in conjunction with the sight base to provide the mechanical tension necessary for rock-solid sight alignment and resistance to impact. Over time and through heavy use—particularly during training cycles, duty carry, or tactical employment—these springs can experience fatigue or loss of tension, degrading sight stability and zero retention. Sons of Liberty Gun Works manufactures this spring to OEM specifications, ensuring compatibility with standard AR-15 front sight posts and assemblies. The minimal weight of 0.01 lbs reflects the precision engineering involved; this is a lightweight but structurally essential component that maintains its spring rate through thousands of cycles.

This replacement spring is ideal for armorer-level maintenance, rifle builds, or quick field repairs when existing springs show signs of wear or reduced tension. Law enforcement and military personnel performing rifle maintenance will appreciate the direct fit design, which eliminates guesswork during reassembly. Installation requires basic familiarity with AR-15 disassembly; the spring seats into the front sight base post area and works with your existing detent and post configuration. Keep a spare on hand for duty weapons, training rifles, or as insurance during extended field operations where sight integrity directly impacts mission readiness.
