ASC — Ammunition Storage Components
Authorized Dealer • Stainless-Steel AR-15 Magazines • Limited Lifetime Warranty
Ammunition Storage Components (ASC) is a Connecticut-based manufacturer specializing in stainless-steel magazines for the AR-15 / M16 platform — a deliberate position opposite the polymer-dominated AR magazine market. The ASC catalog covers .223/5.56, 7.62x39, and 6.5 Grendel in capacities from 10 to 30 rounds, all backed by a Limited Lifetime Warranty. Keep Shooting stocks the workhorse SKU from the line: the 30-round stainless-steel body with the high-visibility orange follower — built to the same drop-test and feed-reliability standards as the rest of the ASC catalog, with a follower color chosen so an empty magazine is instantly identifiable during reloads.
ASC at Keep Shooting
Ammunition Storage Components (ASC) is a Connecticut-based manufacturer specializing in stainless-steel magazines for the AR-15 / M16 platform. The brand sits in a specific position in the modern AR magazine market — one of the few current-production options that deliberately runs against polymer rather than alongside it. Where Magpul, Amend2, Hexmag, Mission First Tactical, and ETS compete on polymer formulations and feature sets, ASC builds the magazine body out of stainless steel — the same positioning category as Duramag, which builds out of anodized aluminum and stainless from C Products Defense. The ASC catalog covers .223/5.56, 7.62x39, and 6.5 Grendel across 10-, 20-, and 30-round capacities, with finish options including the standard stainless body and Marlube black or Flat Dark Earth coatings on selected SKUs. Every ASC magazine ships with a Limited Lifetime Warranty.
Stainless Steel AR-15 30-Round with Orange Follower
The ASC Stainless Steel AR-15 Magazine with Orange Follower, 30-Round is the SKU Keep Shooting stocks from the ASC line. The body is stainless steel — rigid in a way the polymer alternatives can’t replicate, with the long-term storage durability that metal mags hold over polymer bodies (no compressed-set risk on the feed lips over decades). The orange follower is the distinguishing visual feature of this SKU: high-visibility plastic in a color chosen so that an empty magazine is instantly identifiable during a reload — a small but meaningful design choice for shooters running training drills or competition stages where round-count awareness matters. The mag is STANAG-compatible and drops into any AR-15 magazine well alongside the Magpul PMAG, the Duramag aluminum body, and any other USGI-pattern magazine.
Why Stainless Steel — The Anti-Polymer Position
Polymer dominates the modern AR-15 magazine aftermarket for good reasons: it’s lighter than metal, cheaper to produce at scale, more forgiving when dropped on concrete, and the major manufacturers (Magpul, Amend2, Hexmag, MFT, ETS) have spent a decade refining polymer formulations that feed reliably across temperature ranges. But polymer has tradeoffs: feed lips can take a compressed set over years of loaded storage, the magazine body flexes more than metal under load, and the polymer surface is more susceptible to abrasion damage from rough gear contact. Stainless-steel construction addresses each of those tradeoffs directly — rigid body that doesn’t flex, feed lips that hold geometry indefinitely under spring tension, and a surface hardness that shrugs off the kind of contact that scuffs polymer. The cost is weight: a loaded stainless-steel 30-round mag is meaningfully heavier than a loaded polymer mag, which matters more for shooters running multiple loaded mags on a chest rig and less for builders prioritizing rifle storage and durability. ASC and Duramag are the two principal current-production names that have stayed committed to metal-body AR-15 magazines through the polymer wave.

For high-capacity drum and stick options, see KCI USA and Schmeisser (60-round). For the broader AR-15 build-out context, the AR-15 parts catalog pairs with the ASC magazine spend.
