Details:

If your AR feels snappy and loud through the tube, the Neverwear WARTHOG Flat-Wire Buffer Spring is the easy fix. By replacing a standard round-wire spring with a flat-wire profile, it shortens solid height and frees up space in the receiver extension. That extra room lets the spring run its full travel without flirting with coil bind, so the action feels calmer and more consistent from shot to shot.

Why Flat-Wire Changes the Feel

Flat-wire construction spreads load across a wider surface area, so tension ramps more evenly as the bolt cycles. On the gun, that translates to a softer impulse, a cleaner return to battery, and noticeably less spring “twang.” The result is a smoother sight picture that settles faster during strings and a gas system that feels less temperamental.

Drop-In for AR-15 Receiver Extensions

The WARTHOG flat-wire buffer spring is built for AR-15 platforms and drops straight into standard carbine or rifle-length receiver extensions with your usual buffer. No spacers, no specialty parts, no re-tuning. If you run a mix of carbines and rifle-stock uppers, this is a simple way to bring a consistent feel across them.

Built to Run, Built to Last

Made from 17-7PH stainless steel, the WARTHOG flat-wire buffer spring shrugs off heat, fouling, and corrosion better than typical music-wire springs. It’s designed to hold its spring rate over time, which means more rounds spent shooting and fewer mystery malfunctions caused by a tired recoil spring.

Why It Belongs in Your Rifle

Choose the WARTHOG flat-wire buffer spring if you want a quieter tube, a smoother cycle, and a recoil system that feels sorted—without resorting to gas-system gymnastics. Install it, lube as you normally would, and enjoy a calmer, more predictable return on every press.
