Yankee Hill Machine Company Black Diamond M-LOK Handguard Features The Yankee Hill Machine Black Diamond M-LOK Handguard is engineered as a free floating design meaning the handguard does not contact the barrel at any point along its length. That isolation keeps barrel harmonics consistent shot to shot which matters for shooters chasing tighter groups out of their AR-15. At 9.3 inches long and only 9.8 ounces the handguard adds minimal weight to the front of the rifle while still providing a full length mounting platform. The T-marked extended Picatinny top rail runs continuously along the 12 o clock position giving the shooter a uniform surface for mounting optics lights or back-up iron sights wherever they are needed. M-LOK slots positioned at the 3 6 and 9 o clock positions let the shooter attach rail sections lights bipods or grips directly to the handguard without adding unnecessary bulk from a full quad rail design. Machined from aluminum the handguard is built to handle the stresses of repeated accessory attachment and removal without loosening or warping over time. The mid-length sizing is suited to mid-length gas system builds keeping proportions correct for a balanced properly fitting rifle. Shipping with the barrel nut and wrench needed for installation the Yankee Hill Machine Black Diamond M-LOK Handguard is available for sale at GrabAGun for builders who want a slim free float handguard for their AR-15.
