Builders have been adding the Magpul AR-15 MOE Stock Collapsible Mil-Spec FDE to their builds on GunPartPicker since February 2026. All time, it ranks #109 of the 499 stocks and braces builders have added. Builds with this stock are mostly chambered in 5.56 NATO (78%, then .308 Win 11%), split between carbine-length (40%) and mid-length (40%) gas systems, and mostly AR-15 (93%).

Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today 6 of the 8 retailers we track have it in stock. Prices barely moved in September 2026, holding around $35.99, so there haven't been real sales lately. Buying today, the lowest price is $39.82 at Sportsmans Outdoor Superstore, above September's low of $35.99, so a better deal may come back.
