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.

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.

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.
