Customization & Gunsmithing They offer custom rifle builds and have in-house gunsmithing expertise. Their YouTube channel includes FRT trigger installation videos from their gunsmith. They also run regular giveaways featuring custom builds—past promotions included $2,500+ value pistol sets and 6.5 Creedmoor rifles.

Dealer Program MMC offers a dealer application for businesses wanting wholesale pricing.

Their knowledge center covers technical topics like side-charging uppers and FRT trigger installation. Phone support available at +1 (833) 989-3380.

Low prices, massive inventory depth, and fast shipping. If you're building an AR from scratch or need a single component, MMC probably has it in stock at a discount. Their flash sales are legendary among builders—quality parts at half retail.

"Modern Sporting Rifles Done Right" — their tagline says it all. They understand that most builders care about function, not marketing fluff.
