Upgrading the buttstock is one of the highest-impact changes you can make to an AR15 platform for improved ergonomics, repeatable cheek weld, and mission-ready storage. A well-chosen stock transforms how the rifle returns to the shooter’s face and handles dynamic movement while wearing plates or layered gear.
MAGPUL STR CARBINE STOCK is a compact, storage-capable replacement that addresses those needs directly. 
As a drop-in replacement for AR15/M4 carbines using mil-spec sized receiver extension tubes, the STR delivers a low-profile A-frame reinforced polymer design with integrated storage. Shop this product here: Shop this product

Key features and tactical advantages
The STR is a storage-capable version of the CTR with deliberate refinements for field use. Its improved cheek weld reduces head movement when transitioning between optics and irons, while two water resistant battery tubes provide secure internal storage for small batteries, spare parts, or survival items. The compact reinforced polymer A-frame keeps weight low without sacrificing strength, and the replaceable 0.30″ thick rubber butt-pad ensures positive shoulder purchase to prevent slippage even when wearing body armor or modular gear.
Additional practical features include two integral sling loops and a reversible push-button QD sling mount that lets you place a quick-detach swivel in the position that fits your carry style. The STR’s drop-in compatibility with mil-spec tubes makes installation straightforward for most AR15 and M4 platforms. View product details and pricing: View product details and pricing
Fitment, use cases, and value

At a listed price of $80.7, it presents strong value for a reinforced polymer stock with integrated features normally found on higher-priced components.
