Smith & Wesson M&P-15 Sport III 5.56 NATO 30rd
1 in stock
Description
This Pre-Owned Smith & Wesson M&P-15 Sport III is a semi-automatic 5.56 NATO rifle built on the company's current-generation Sport platform, introduced in 2024 as the successor to the Sport II. The update moved the line to a mid-length gas system and a free-float M-LOK handguard, two changes that address the most common complaints about earlier entry-level ARs. Shooters looking for a straightforward duty-pattern carbine for range work, training classes, or general-purpose use will find the layout familiar and easy to build on.
This rifle is presented in used condition and comes with one 30-round magazine and a vertical grip mounted to the handguard. The 15-inch handguard leaves plenty of M-LOK real estate for lights, sling hardware, or a bipod, and the full-length top rail accepts optics and backup irons without needing a riser adapter.
Smith & Wesson M&P-15 Sport III Features
- Mid-length direct impingement gas system that softens the recoil impulse and reduces wear compared to a carbine-length setup on a 16-inch barrel
- 15-inch free-float M-LOK handguard that keeps barrel harmonics undisturbed by sling tension or shooting support while leaving room for accessory placement
- Full-length Picatinny top rail running the length of the receiver and handguard for continuous optic and iron sight mounting
- 4140 steel barrel with 5R rifling and a 1:8 twist, a rate that stabilizes a wide spread of common 5.56 and .223 bullet weights
- Threaded 1/2x28 muzzle wearing an A2 flash hider, ready for other muzzle devices or a compatible suppressor mount
- 6-position collapsible stock for fitting different shooters, body armor, and shooting positions
