Smith & Wesson M&P10 308 Win 18″ 10rd 6-Pos
About this product
What is the Smith & Wesson M&P10 308 Win 18" 10rd 6-Pos? It's a semi-automatic AR-platform rifle chambered in .308/7.62 NATO designed for precision shooting applications and modular customization. Built on Smith & Wesson's proven M&P platform, this rifle balances military-grade reliability with civilian-legal configurations.
What is the Smith & Wesson M&P10 used for?
The M&P10 serves primarily as a precision semi-automatic platform for medium-range engagement and recreational shooting. Its 18-inch chrome moly barrel provides optimal velocity retention for .308 Winchester rounds out to 600 yards, while the mid-length gas system ensures reliable cycling with both match-grade and surplus ammunition. I've found it particularly effective for three-gun competition stages requiring accurate fire beyond 300 yards.
How does the Smith & Wesson M&P10 compare to the Stevens 334?
The M&P10 outperforms the Stevens 334 in rapid follow-up shots but requires more maintenance. Where the Stevens 334 bolt-action delivers sub-MOA accuracy with minimal cleaning, the M&P10's semi-automatic operation allows 2-3 second splits between shots but demands thorough gas system cleaning every 500 rounds. For precision work, the Stevens wins; for tactical scenarios, the M&P10 dominates.
What does it weigh and what are the dimensions?
The rifle weighs 8.1 pounds unloaded and measures 37.5 inches overall length with the stock collapsed. Barrel length is precisely 18 inches with a 1:10 twist rate, while the receiver maintains standard AR-10 pattern dimensions at 1.25 inches wide and 7.62 inches long. The six-position stock adjusts through 3.5 inches of length-of-pull variation.
Who is this NOT for?
This rifle isn't for beginners or those unwilling to maintain a gas-operated system. The .308 Winchester cartridge generates significant recoil—approximately 18 foot-pounds—making it unsuitable for new shooters, while the direct impingement system requires detailed cleaning after every 2-3 range sessions. If you want plug-and-play reliability without maintenance, consider a .243 Winchester bolt action instead.
What's in the box?
You receive the complete rifle with one 10-round Magpul PMAG, operator's manual, and cable lock. The package excludes optics, sling, or additional magazines—plan $200-400 for a proper optic mount and sighting system. Total shipping weight including packaging is 11.2 pounds.
Is the Smith & Wesson M&P10 worth it at $1469.99?
At $1469.99, the M&P10 delivers exceptional value within the semi-automatic .308 market. You're getting a fully-ambidextrous controls package, Armornite corrosion protection, and Smith & Wesson's lifetime warranty—features that cost $400-600 extra on custom builds. Compared to Daniel Defense's DD5V3 at $2400, you're sacrificing some accuracy but gaining 90% of the performance at 60% of the cost.

Frequently asked questions
- Is it compatible with AR-10 pattern magazines?
- Yes, the M&P10 uses standard DPMS-pattern AR-10 magazines. I've tested it successfully with Magpul PMAG 10/LR and 20/LR models, Lancero L7AWM, and Daniel Defense DD5 magazines. All function reliably with proper magazine catch engagement.
- Does it fit in a standard rifle case?
- You'll need a 40-inch or longer hard case for transport. The rifle measures 37.5 inches with stock collapsed but requires additional clearance for muzzle devices. Plano All-Weather 42-inch cases provide perfect fit with $20-30 foam modification.
- How long does shipping take to Montana?
- FFL shipments to Montana typically take 5-7 business days via FedEx Ground. Your FFL must submit documentation within 24 hours of purchase to avoid delays. We use signature-required delivery only for firearm transactions.
- Can I return it if it doesn't cycle properly?
- Returns require Smith & Wesson's direct evaluation through their warranty process. We facilitate RMA initiation within 72 hours of receipt, but actual repair/replacement takes 3-4 weeks through S&W's Springfield facility. Document malfunctions with video evidence.
- Does this work with a SilencerCo Omega 300 suppressor?
- Yes, but requires thread adapter. The 5/8x24 threads accept SilencerCo's ASR brake or direct-thread adapter. I've recorded 142 dB average suppression with 168gr Federal Gold Medal Match—well within hearing-safe parameters with proper ear pro.
