The handguard, also known as a “rail” is one of the most important parts of an AR-15 or AR-10 type rifle. Many builders prefer maximum versatility, accuracy and comfort using a free-floated M-LOK rail. While others like the classic aesthetic and simplicity of a drop-in quad-rail type handguard. We offer a variety of lengths, materials and mounting systems suitable for any build. You can find the best handguard deals from the nation’s top manufacturers right here at AR15Discounts.com, all backed by our satisfaction guarantee.
