LMT MRP Barrel Change

Do you want to know how to change the barrel in your LMT MRP or MWS weapon system? Watch this short video to learn how. James Ferguson of XMTG changes the barrel on his LMT MRP from a .224 Valkyrie to a 5.56 in preparation for an upcoming ammunition test. Barrel swaps are quick and easy with the supplied torque wrench.

Never use a torque wrench to loosen screws, just a suggestion, and always make sure to take tension off of the torque wrench when not using, dial back to zero when stored.

May want to consider using seom AEROShell 33mS Synthetic grease on the barrel shoulder when installing, to prevent future seizing.

I wonder if LMT torque wrench comes with barrel or is my FAT wrench should be sufficent?

[@brindle1980]

Could u show a look at your torque wrench when it's set at 140 inch pounds

[@nickdinnocenti5341]

What torque wrench do you use? And what is the size/dimensions for the screw for the 2 bolts?

[@xmtgfirearmstrainingacadem4426]

I use the one that came with the rifle from LMT. They no longer send that one out. The bolts are the same size. I do not know the size. You can buy spares from LMT.
