The Amend2 50 Beowulf magazine delivers reliable feeding for AR-15 platforms chambered in large-bore cartridges. Purpose-built for shooters running .458 or .50 Beowulf uppers, this 10-round magazine fills a critical gap where standard AR magazines fall short. The advanced polymer construction handles the demands of big-bore cartridges without the weight penalty of aluminum alternatives. For hunters pursuing large game or shooters who appreciate serious stopping power, this magazine provides the dependable function these hard-hitting calibers require.

Amend2 engineered this magazine with a heavy-duty stainless steel spring that resists memory and corrosion, maintaining consistent feed pressure through thousands of cycles. The four-way anti-tilt polymer follower tracks smoothly regardless of how many rounds remain, preventing the nose-dive failures that plague lesser designs. Impact-resistant polymer walls withstand drops and rough handling while aggressive texturing on the front and back surfaces ensures positive grip during mag changes. The body accepts Cerakote finishes for those wanting color coordination with their build. At 1 pound, weight stays reasonable for a big-bore magazine. Every unit ships from Amend2's Idaho Falls facility, manufactured entirely in the USA.
This magazine excels in hunting applications where .50 Beowulf's terminal performance on hogs, deer, and bear demands absolute reliability from supporting components. It also serves well at the range for shooters who simply enjoy the controlled violence of big-bore AR platforms. The 10-round capacity balances adequate ammunition supply against manageable magazine length. Pair it with quality ammunition and proper rifle maintenance for consistent performance. We stock this magazine ready to ship for your next big-bore build.
