AICS Long Action .338 LM Black 5rd SSSF Magazine 00100-0005

AICS Long Action .338 Lapua Magnum Magazine | 5-Round | SSSF (Single-Stack, Single-Feed) | Black | Part: 00100-0005 Run your .338 Lapua Magnum with the magazine trusted in precision rifle circles. The AICS Long Action .338 LM 5-Round SSSF Magazine (Black) delivers rock-solid feeding, repeatable lock-up, and the rugged build quality long associated with Accuracy International Chassis System (AICS) components. Purpose-built for long-action .338 Lapua Magnum rifles that use AICS-pattern single-stack/single-feed magazines, this 5-rounder is the go-to choice for PRS/NRL-style long-range, ELR practice, hunting, and duty applications where feeding reliability and consistent stack geometry matter. Why This AICS .338 LM 5-Round SSSF Mag Stands Out SSSF Geometry for Big Magnums: The single-stack, single-feed internal layout keeps long, heavy .338 LM bullets aligned and presented correctly to the bolt face—smooth, controlled feeding even under recoil and field conditions. Proven AICS Pattern: Built to the AICS specification for long-action .338 Lapua systems, supporting widespread chassis and bottom-metal compatibility (see fitment notes). Rugged Steel Construction: A hardened steel body resists dents and feed-lip deformation for long service life across training cycles and rough field use. Corrosion-Resistant Black Finish: Low-glare, durable coating helps shrug off weather, sweat, and dust while blending with rifle lines. 5-Round Capacity: The sweet spot for prone work, hunting blinds, and match stages that demand reliable feeding without excess bulk. Field-Serviceable Design: Simple disassembly for cleaning and inspection after high round counts or sandy, wet conditions. Key Features at a Glance Caliber: .338 Lapua Magnum (long action) Capacity: 5 rounds Format: SSSF – Single-Stack, Single-Feed Body Material: Steel with black protective finish Pattern: AICS (Accuracy International Chassis System) Part Number: 00100-0005 Color: Black Performance You Can Feel Consistent Presentation: SSSF feed geometry minimizes nose-dip and misfeeds with long ogive, high-BC projectiles. Reliable Under Recoil: Stout spring rate and properly formed feed lips support uniform cartridge release—critical for heavy magnum recoil. Repeatable POI Confidence: Reliable chambering cycle after cycle helps preserve your rifle’s cold-bore to hot-bore confidence in long-range sessions. Ideal Use Cases Long-Range / ELR Practice: Smooth feeding with 250–300+ grain .338 LM loads while spotting trace and running data. Hunting & Backcountry: 5-round capacity with a compact footprint for prone, tripod, or blind setups. Precision Matches (Open/ELR): AICS-pattern compatibility and SSSF reliability for stages that punish inconsistent magazines. Tactical/LE: Durable, corrosion-resistant magazine for duty rifles chambered in .338 Lapua Magnum. Fitment & Compatibility Notes AICS Pattern: Designed for AICS-pattern long-action .338 Lapua Magnum bottom metal/chassis and actions that specify SSSF magazines. Check Your System: Some manufacturers use AICS-pattern but may specify DSSF (double-stack, single-feed) or proprietary feed geometry. Confirm your rifle/bottom-metal requirements before purchase. Overall Cartridge Length (COAL): Verify your load’s COAL fits within the mag’s internal length; very long bullets or seated-out handloads may exceed internal dimensions. Care & Maintenance Routine Cleaning: Disassemble and wipe the interior tube, follower, and spring after dirty or wet range days. Light Lubrication: Run dry or nearly dry—excess oil attracts dust and grit that can slow follower travel. Inspect Feed Lips: After impacts or drops, check for deformation; replace if feed becomes inconsistent. Mark & Rotate: Label magazines and rotate between training and field use to track service life. Pro Tips for Best Results Confirm Torque & Fit: Ensure your bottom-metal and action screws are torqued to spec—mag alignment affects feed angle. Test Your Load Stack: Run your match or hunting load through a full magazine to verify reliable chambering from various shooting positions. Keep a Spare Spring Kit: High-round-count shooters benefit from periodic spring replacement to maintain consistent stack pressure. Frequently Asked Questions Q: Will this work in my chassis? A: If your long-action .338 Lapua Magnum rifle uses AICS-pattern SSSF magazines, it should fit. Always verify with your chassis/bottom-metal manufacturer. Q: What’s the difference between SSSF and DSSF? A: SSSF holds rounds in a single vertical column and feeds from the center. DSSF stacks rounds in a staggered column but still feeds single-center. Your action/bottom metal is typically designed for one or the other. Q: Can I load to very long COAL for ELR? A: The magazine supports standard .338 LM COAL. Extremely long, seated-out bullets may require single-loading or a chassis/DBM designed for extended internal length. Q: Is the follower polymer or metal? A: Followers may vary by production. Regardless of material, the follower and spring are tuned for reliable, smooth feeding with .338 LM. Q: Is it compatible with .300 Norma or .300 PRC? A: This model is specified for .338 Lapua Magnum. Use magazines spec’d for your cartridge and action to ensure proper feed geometry.
