Smith & Wesson’s Updated M&P15 Sport III AR Platform Rifle

Smith & Wesson's Updated M&P15 Sport III AR Platform Rifle

Smith & Wesson rolled out the first M&P15 Sport rifle way back in 2010. It was a well-appointed, budget-priced “starter” AR-15 that just about everyone could afford. Seven years later they updated it with the M&P15 Sport II. The deuce got a forward assist and they changed the rifling from 1:8 from the 1:7 twist of the original.

Now, another seven years later, it’s time for another upgrade with the M&P15 Sport III. The trey replaces the A2-style handguard and sights with a low profile gas block to fit under a full-length M-LOK handguard. And the price is still very reasonable.

Smith & Wesson Brands, Inc., a leader in firearm manufacturing and design, announces today the release of the new M&P15 Sport III rifle. 

Designed to perform under various conditions, the Smith & Wesson Sport Series is as versatile as it is reliable. Building on the proven Sport II platform, the next iteration comes equipped with enhancements to increase performance while being offered at a lower price. The Sport III is a gas-operated semi-auto MSR chambered in 5.56 NATO/223 REM, and is offered in 30+1 and 10+1 capacities. Upgrades to this platform include a 16-inch Armornite coated barrel with a threaded muzzle, 5R rifling, and a 1:8-inch twist that allows for a wider variety of ammo to be used. The barrel, housed in a free-floating 15-inch M-LOK handguard with a full-length Picatinny-style rail, offers more options to accessorize than previous generations. The Sport III utilizes a mid-length gas system to help mitigate felt recoil when shooting and it also ships with a 6-position adjustable stock, polymer grip, bolt forward assist, and chromed firing pin.

  1. I bought my Sport II model on a whim for around $500 plus tax, after watching IV8888’s meltdown video. He put the complete upper onto a full auto lower and shot it at full auto as quickly as he could change mags, including a couple 100 round mags. It went something like 800 rounds before it plugged up–I think the gas tube failed. It’s not as refined as a lot of others on the market, but that was impressive and I found it on sale at The Fin. Got me started with ARs.
