A quality AR-15 buffer tube spring is one of those invisible upgrades that pays dividends in how your rifle feels and sounds when you're running it hard. The TacFire MAR046 6-Position Buffer Tube Spring for AR-15 Rifles is a USA-made replacement spring engineered to work with standard AR-15 buffer tube systems. Built from piano wire material, it's designed to absorb and manage the spring pressure that cycles your bolt carrier group, helping reduce the audible "twang" that can occur when firing. Whether you're at the range, in the field, or training on your own, a solid buffer spring keeps your action cycling reliably and keeps things quieter.
The 6-position designation refers to compatibility with AR-15 stocks that use standard mil-spec buffer tube routing, making this a straightforward swap for shooters who want to refresh worn springs or upgrade to a component built for consistency. Since the buffer spring is fundamental to your rifle's reliability and felt recoil management, choosing a quality domestic-made part matters. TacFire's use of piano wire — the same high-carbon steel found in precision applications — means this spring will maintain its rate and performance through thousands of rounds.
If you shoot an AR-15 and notice excessive noise from the buffer tube assembly, or if you're building or upgrading a rifle and want a reliable factory replacement, this spring is a solid, no-fuss choice that handles the job without breaking the bank.

The TacFire MAR046 is designed for AR-15 rifles with standard 6-position buffer tube systems. If your rifle uses a mil-spec buffer tube, this spring will be compatible. Verify your buffer tube type before ordering.
You receive the TacFire MAR046 buffer tube spring. Installation requires removing your stock and buffer assembly; no additional tools beyond a standard AR-15 takedown are needed.
The piano wire construction absorbs and manages the spring pressure more effectively than lower-quality alternatives, which helps dampen the resonant "twang" some shooters notice when the bolt carrier cycles. The improvement is subtle but noticeable, especially in controlled shooting environments.
