Frequently Asked Questions

Is this magazine permanently blocked to 10 rounds, and can it be restored to 30?

Yes — ASC uses a proprietary block and rivet system specifically designed for permanence. The block is not intended to be removed, and attempting to do so would damage the magazine. This ensures the magazine remains compliant with California's standard-capacity magazine restrictions under current state law.

Will this magazine fit my AR-15, and does the 30-round body cause any clearance issues?

This magazine is designed to fit any standard AR-15, M4, or M16 lower receiver that accepts USGI-pattern magazines — the vast majority of AR-platform rifles on the market. The 30-round body profile is identical to a standard 30-round mag, so it seats and drops free normally. It will not fit AK-pattern or other non-AR platforms.

Why choose a stainless steel magazine over an aluminum or polymer option?

ASC's heat-treated 410 stainless steel construction offers several practical advantages: it won't swell in high heat or crack in cold temperatures the way polymer magazines can, and it resists the dents and deformation that standard aluminum USGI magazines are prone to. For a duty or defensive firearm, stainless steel provides a longer service life and more consistent feeding over time.
