Midwest Industries Handguard Features The Midwest Industries Handguard is machined from 6061 aluminum for a rugged lightweight forend that stands up to hard use without adding unnecessary weight to the MPX platform. With 24 full M-LOK compatible slots and 4 half slots spread across its 8 inch length and 2.06 inch width shooters have nearly continuous mounting real estate for lights foregrips and slings. The 1.8 inch internal diameter is sized to clear the MPX s barrel and gas system while keeping the overall profile slim and easy to grip. A heat treated 4140 steel retaining clip finished in phosphate locks the handguard securely to the receiver for a tight rattle-free fit. A five slot M-LOK compatible rail section ships with the handguard giving shooters an immediate mounting point without needing to purchase additional rail segments separately. At just 6.6 ounces the handguard adds minimal weight to the MPX while still providing full coverage and a secure accessory mounting platform. Built entirely in the USA this handguard is an easy drop-in upgrade for MPX owners looking to modernize their rifle s forend. It suits competition shooters home defense users and anyone who wants more flexible accessory placement on their Sig Sauer MPX.
