Description The storage-capable version of the flagship Magpul MOE SL carbine stock, the MOE SL-S (Storage) Carbine Stock - Mil-Spec is a direct replacement buttstock for AR15/M4 carbines.The sleek profile, dual-side release latches, and waterproof battery tubes make it the slimmest storage tube stock available. The SL-S provides an enhanced cheek weld and true, O-ring sealed, 10m waterproof storage area desired by many, but fits it into the narrowest package possible to allow a more upright head position and minimize bulk. A rolled toe and angled rubber butt-pad are optimized for use with body armor, and an ambidextrous QD sling swivel socket is included. A unique leaf-spring tension system provides a solid fit on mil-spec receiver extensions, with slightly less friction than the original SL. The MOE SL-S is the most intuitive, comfortable, and efficient storage stock available.Features & Specs:Collection: Collapsible Storage AR StocksPlatform: AR10, AR15, M4, M16, M110, SR25Compatibility: Mil-Spec sized carbine receiver extension tube (not included) from manufacturers such as Colt, LMT, Ruger, S&W, SIG, and othersLOP, M4 Collapsed: ~10.9 in.LOP, M4 Extended: ~14.2 in.LOP Adjustment Range: 3.3 in.Length, max: 7.3 in.Weight: 12.8 oz.Weight, w/ receiver extension: 16.8 oz.Width, max: 2.4 in.Magpul Black MOE SL-S Carbine Stock â Mil-SpecDesigned for use with Mil-Spec buffer tubesFeatures a streamlined profile for improved maneuverabilityIntegrated QD sling swivel sockets for versatile sling attachment optionsSloping cheek weld for enhanced shooter comfort and stabilityDual-side release latch for easy and convenient stock adjustmentMade from durable polymer construction for lightweight and rugged performanceCompatible with a wide range of AR-15/M4 carbinesTrusted accessory from Magpul Industries for reliability and qualityMade in the USANOTE: There are two basic sizes of M4 Carbine receiver extensions (buffer tubes): Mil-Spec and Commercial-Spec.
