TacFire MAR046-A2 AR-15 A2 Length Buffer Tube Spring

The TacFire MAR046-A2 is an AR-15 A2-length buffer tube spring built for direct fitment in A2-style buffer assemblies.

Manufactured from piano-wire spring steel with a stainless steel finish, this buffer spring resists corrosion and wear through heavy use and demanding field conditions. The A2-spec length delivers the proper spring tension and travel for AR-platform rifles set up with a mil-spec A2-style buffer tube.

Designed as a drop-in replacement, the MAR046-A2 installs inside the buffer tube behind the buffer weight and is at home in standard AR-15 and M16 lower receiver setups. Made in the USA.
