Smith & Wesson M&P15-22 .22 LR Semi-Auto Rifle, First-Gen Quad-Rail, 16.5" Threaded Barrel
The first-generation Smith & Wesson M&P15-22 offers a lightweight, dedicated rimfire AR platform with features that mirror a duty carbine. Its polymer upper and lower receivers keep weight down while preserving the familiar control layout of an AR-15. A carbon-steel pencil barrel threaded 1/2x28 and capped with an A2 flash hider broadens accessory options, and the 6-position collapsible stock lets shooters tailor length of pull. An ambidextrous safety, recessed magazine release, and full polymer quad-rail handguard round out a package favored by trainers, competitors, and law-enforcement agencies alike.

This rifle is the early quad-rail variant produced between 2009 and 2015, identifiable by its HBS serial prefix and full polymer receiver set. The configuration delivers an authentic AR-15 feel while reducing overall weight for extended range sessions.
The 16.5" carbon-steel barrel features a 1:15 right-hand twist optimized for standard .22 LR ammunition. The threaded muzzle (1/2x28) ships with an A2 flash hider, allowing easy attachment of muzzle devices or suppressors.
Controls mirror centerfire counterparts: an ambidextrous safety selector, recessed magazine release, and standard charging handle support realistic training. The blowback action cycles reliably with a wide range of rimfire loads, and the 25-round magazine provides ample capacity for drills or plinking.
A six-position collapsible stock sets the length of pull at 10.5" in its shortest position, accommodating shooters of various sizes. The polymer quad-rail handguard offers four full-length Picatinny rails for lights, optics, or additional accessories—complemented here by the included vertical fore-grip.
Finished in matte black throughout, the M&P15-22 maintains a clean, professional look while resisting glare and handling marks. Made in the United States, this model remains a popular choice for economical training and practical rimfire competition.
