TacFire AR-15 Rifle Buffer Spring — A2 Length | Smooth Cycling for Fixed-Stock Builds (SKU MAR046-A2 | UPC 811261023567) Give your fixed-stock AR the reliable, consistent recoil impulse it was designed for with the TacFire AR-15 Rifle Buffer Tube Spring — A2 Length. Purpose-built for rifle-length receiver extensions (A2/A1 fixed stocks), this quality action spring helps ensure positive bolt return, dependable lock-back, and repeatable ejection patterns across a wide range of .223/5.56 loads and comparable AR platforms. Whether you’re refreshing a legacy rifle, completing a clone build, or standardizing an armory, MAR046-A2 delivers smooth cycling at a value that makes sense. Why Choose the TacFire A2 Rifle Spring? True rifle-length spec: Sized for A2/A1 fixed-stock buffer systems—ideal for classic builds, DMR setups, and feature-compliant configurations. Smooth, consistent cycling: Proper spring rate supports reliable feeding, extraction, and bolt catch function over long round counts. Durable, dependable construction: Built to withstand repeated compression cycles without taking a set prematurely—fewer stoppages, more range time. Easy drop-in replacement: Install in minutes in any rifle-length receiver extension with a standard rifle buffer. Great for maintenance plans: Affordable enough to rotate proactively as part of scheduled service intervals. Compatibility Note: This is a rifle-length (A2) action spring for fixed-stock systems. It is not a carbine spring and is not intended for carbine-length receiver extensions or collapsible stocks. Key Features & Benefits Format: Rifle-length action/buffer spring (A2) Intended System: Fixed-stock A2/A1 buffer tube and rifle buffer Function: Returns the bolt carrier group to battery, supports reliable lock-back on empty, and stabilizes recoil impulse Brand / SKU: TacFire MAR046-A2 UPC: 811261023567 Ideal Use Cases Refurbishing classic rifles (A2, SPR, DMR, and state-compliant fixed-stock builds) Reliability refresh for rifles showing sluggish return-to-battery, short-stroking, or inconsistent lock-back Armory standardization where predictable recoil and parts commonality matter Installation Overview (Best Practices) Unload & clear the firearm—verify chamber and magazine are empty. Remove buttplate/endcap on your fixed stock to access the rifle-length receiver extension. Depress buffer retainer and remove the rifle buffer and old spring. Insert new spring and rifle buffer into the extension; ensure the buffer is captured by the retainer. Function check: Hand-cycle the action to verify smooth travel and proper bolt catch operation before live fire. Tip: If you’ve changed gas system components, muzzle devices, or ammunition types and see erratic ejection, evaluate gas, buffer weight, and spring condition together for the best results. Maintenance & Care Replace proactively: Springs are wear items. High-round-count rifles benefit from periodic replacement to preserve reliability. Keep it clean: Grit and heavy fouling inside the receiver extension can accelerate wear—wipe down during routine maintenance. Avoid over-lubrication: Excess oil can attract debris; a light film is sufficient. Specifications (Quick Reference) Product: AR-15 Rifle Buffer Spring (A2 length) System: Rifle-length receiver extension with rifle buffer Platform: AR-15 pattern (.223/5.56 and similar) Model/SKU: MAR046-A2 UPC: 811261023567 Quantity: 1 spring (buffer and tube not included) FAQs Q: Will this work in a collapsible stock? A: No. Collapsible stocks use carbine-length receiver extensions and carbine springs/buffers. This spring is for rifle-length A2/A1 systems only. Q: Do I need a new buffer too? A: Not necessarily. If your rifle buffer is in good condition, you can replace just the spring. For tuning or unknown round counts, consider replacing both. Q: What symptoms suggest my spring is worn out? A: Sluggish return to battery, failure to lock back on empty with known-good magazines, or noticeably softer spring tension during reassembly. Q: Is this compatible with .223 Wylde or 6.5 Grendel? A: If the rifle uses a rifle-length A2/A1 buffer system, this spring is generally compatible regardless of caliber. Always verify your setup.
