The ASC .308 10-round magazine is built with American-made quality from start to finish, using .032 gauge 410 stainless steel alloy that's heat-treated for strength. The entire manufacturing process happens right here in the USA, which sets it apart from a lot of the alternatives out there. What you're getting is a magazine that won't swell in heat or crack in cold, delivering real durability for both casual range sessions and serious use.
ASC finishes these magazines with a proprietary Marlube coating that works differently than typical magazine coatings. Instead of wearing off with use, Marlube is designed to wear in, burnishing into the metal surface and providing self-lubricating properties that actually improve over time. The stainless steel construction combined with chemical corrosion treatment means you're looking at a magazine that stands up to moisture, salt spray, and the elements without degrading. This is the kind of detail that matters if you shoot in various conditions.
The interior length of 2.865 inches gives you flexibility if you reload your own ammunition. That's notably longer than some polymer magazine options, which can be restrictive for custom loads. The enhanced anti-tilt polymer follower keeps rounds properly aligned during loading and feeding, and the chrome silicon spring provides consistent tension cycle after cycle. The floor plate is stainless steel with a matte black powder coat, so it resists corrosion and won't show wear easily.
This magazine is designed specifically for SR-25/DPMS pattern rifles. Make sure your rifle is a DPMS or SR-25 platform before ordering, as magazine fitment varies across different AR-10 manufacturers. The 10-round capacity keeps things manageable for bench shooting, hunting, or situations where capacity is limited.
This magazine is designed specifically for SR-25/DPMS pattern AR-10 rifles. There's no universal standard for large-frame AR-10 magazines, so it's important to verify your rifle uses DPMS or SR-25 patterns before purchasing. It will not fit Armalite AR-10B or Springfield M1A-style platforms.
ASC's Marlube coating is a wear-in rather than wear-off finish, which means it actually improves the more you use it. As you load and unload the magazine, the coating burnishes into the metal surface and provides self-lubricating properties that reduce friction over time, while also protecting against corrosion.
Yes, this is actually a popular choice for reloaders. The interior dimensions of 2.865 inches allow for longer cartridge overall lengths compared to many polymer magazines, giving you more flexibility with custom loads. Just verify your specific reload specs fit within these dimensions.
Stainless steel won't swell in heat or crack in extreme cold like some polymers can, and this ASC magazine resists corrosion even in harsh conditions. The tradeoff is slightly more weight. Many shooters prefer steel for durability and longevity, especially for rifles that see regular use or storage in variable conditions.
