Lantac’s LA-SF15 DMR is ready for action right out of the box, and comes packed with Lantac exclusive features. The heart of the LA-SF15 DMR is Lantac’s own Enhanced Bolt Carrier Group (E-BCG). Built to exceed stringent military specifications, the E-BCG carrier is precision machined from 8620 steel and the bolt from Carpenter 158/9310 steel. Both of which are built to exacting dimensions, case hardened, and given a durable finish to shrug off fouling and corrosion. The E-BCG is further fitted with a 17-4PH stainless steel Lantac CP-R360 domed head cam pin, hand polished, and hardened to H900 condition – this further reduces friction and wear within the upper receiver. Another Lantac-Exclusive feature of the LA-SF15 DMR is the Dragon Muzzle Brake, which offers improved recoil management and muzzle rise thanks to a unique Short Energy Pulse system to reduce the length of recoil so repeating shot energy cannot overlap and knock the shooter off target. Other features of the LA-SF15 DMR include an enhanced forged receiver set with an internally flared magazine-well to assist in high-stress reloading, and generous ventilation along the handguard helps dissipate the heat generated from prolonged firing. In addition, the LA-SF15 DMR features a full-length picatinny rail with plenty of space for the use of iron-sights, optics, and clip-on devices, and multiple M-LOK attachment points on the handguard accommodate the use of lights, lasers, and other M-LOK accessories.
