Accurate Mags AICS Long Action Rifle Magazine .300 WIN MAG SSSF 3.850" 5/rd Black

The Accurate Mags AICS Long Action Rifle Magazine in .300 WIN MAG is a purpose-built, single-stack single-feed magazine designed for precision rifle shooters who demand reliability with magnum cartridges. Built from heat-treated steel and finished with a Teflon coating for smooth operation and durability, this 5-round magazine holds the 3.850" cartridge length specification and fits AICS-pattern rifle actions. Whether you're setting up a long-range hunting rifle, building a precision rifle for competition, or maintaining a backup mag for field use, this magazine delivers the dependability magnum shooters expect.

Single-stack single-feed (SSSF) design prioritizes controlled feeding and reliability—critical when you're taking a shot that matters. The Teflon-coated steel construction resists corrosion and wear, handling the rigors of field use and regular cleaning cycles. The 5-round capacity suits hunters and long-range shooters who value accuracy over volume, and the fixed cartridge length specification ensures consistent feeding geometry for your .300 WIN MAG ammunition.

Accurate Mags magazines are engineered around AICS (AI Chassis System) compatibility, meaning they integrate seamlessly with chassis-built rifles and AICS-pattern magazine wells found across modern precision platforms. If you're running a precision rifle system, this magazine addresses a core need: feeding magnum rounds reliably, shot after shot.

Frequently Asked Questions

What rifles does this .300 WIN MAG magazine fit?

This magazine is built to AICS Long Action specifications and works with any rifle using an AICS-pattern magazine well or chassis system. Common platforms include Accuracy International chassis rifles, Remage builds, and other precision systems designed around the AICS standard.

Is this magazine compatible with my .300 WIN MAG hunting or precision rifle?

If your rifle accepts AICS Long Action magazines and chambers .300 Winchester Magnum, this magazine will work. The 3.850" cartridge length specification is standard for .300 WIN MAG, so it accommodates factory and most handloaded rounds in this caliber. If you're unsure whether your rifle uses AICS magazines, check your action or chassis documentation.

Why single-stack single-feed for a magnum cartridge?

Single-stack single-feed design controls how each round is presented to the chamber, improving feeding reliability with longer, heavier magnum cartridges. It's a design choice favored in precision rifle applications where every round must feed flawlessly.

What's included?

You receive one magazine. The 5-round capacity is intentional—precision rifle shooters often use magazines matching their typical shooting sessions, and the lower round count works well with single-stack feeding geometry.
