MRP/MWS locking screws use a T-30 head and should be torqued to 140 in/lbs for optimum performance. The LMT Torque Wrench is designed to this exact specification. Need a tutorial? Check out our video on YouTube!
No, LMT barrels are not cold hammer forged. Commonly confused with CHF, is our cryogenic stress relieving process. This is done on all barrels, both chrome-moly and stainless.
Good news! You can shoot both NATO 762 and commercial grade 308 Win through your MWS rifle. The commercial spec ammo actually runs slightly higher pressures over the 7.62X51. However we build our barrels to withstand greater pressure than either calibers produce. However we do NOT recommend use of hand loaded ammo in either caliber.
MRP (5.56/.223) and MWS (7.62/.308) platforms are independent of one another. LMT barrels made for the monolithic platforms are proprietary. While all MWS barrels are compatible with that platform, the MRP hosts two upper receiver lengths, each with their own capabilities.
There is no set barrel life or round count for our barrels. Heat is the enemy of steel. Depending on how hot you get your barrel, and for how long that temperature is sustained, can have great affect the life of a barrel. Barrel material like stainless steel and chromoly with a chrome lining are affected differently. The last factor that can affect barrel life is maintenance or care and bullet type. Maintaining your equipment is crucial to longevity, the bore of a rifle is no exception. Different types of bullets and jackets interact differently with the rifling, make sure to use proper maintenance for your particular ammo.
The LMT MWS is one of the leaders in the commercial AR-10 market. One big feature that sets our weapons apart is the ability to quickly change barrel types and calibers while maintaining less that 1 MOA shift. Typically AR type weapons are plug and play thanks to the US DOD and industry standard of specifications. The “AR-10” family of rifle does not follow a specific industry standard. While our MWS is a true SR-25 pattern and will work with Knights Armament equipment, we highly suggest to avoid any issues derived from a stack up of tolerances, you only use LMT certified parts when building your heavy gun.
The LMT Enhanced BCG has many features to cure or improve common issues on the AR-15 type weapon system. See below the list of features and advantages to using the Enhanced Bolt Carrier Group.
Reduced surface carrier rails: These rails reduce friction on the upper receiver, improve lubricity by allowing oil to travel in between the contact patches and allow a gap for debris to move away from building up on the carrier body.
