The existing install videos for this rail are not very good. His build uses a standard AR-10 bolt, a Vltor charging handle, a precision upper and lower, a Criterion barrel with a Strike Industries King Comp, and this Odin Works M-LOK rail. He also wanted the receiver lapped for accuracy. Hand lapping took about 10 minutes. We cleaned the upper and moved on. Next we bedded the barrel with the same Indian Head gasket sealer I use. We wrapped the barrel in a rag so compound stayed off the contour, coated the outside of the extension, and slid the upper into place. The Odin Works rail uses a receiver extension with a gas-tube alignment feature. Thread it onto the upper until tight, then back it off until the gas-tube holes in the extension and upper line up. Like the Lancer carbon rail on my AR-15, a barrel nut threads into that extension and clamps the barrel-extension shoulder to the upper. I wanted to use a torsion bar in the extension lugs, but Odin includes a gas-tube alignment pin that must stay in while you torque. That blocks the torsion bar. The upper goes in a vise and you torque with a barrel-nut wrench. Align the extension, insert the pin so the extension cannot rotate, then torque. The wrench from my SLR Solo Ultralight on the 6.5 Creedmoor also fits this Odin nut, so we used it. Keep the wrench axis 90 degrees to the torque-wrench head. In line with the wrench you get a false reading. We torqued and loosened three or four times to season the threads, backed the nut off, applied the thread locker that comes with the rail, ran the nut back in, and final-torqued. I believe that was 50 ft-lb. We pinned the gas tube to the block and installed the block. It was tight; twisting slightly while pushing helped. I looked down the bore to confirm the tube sat at 12 o’clock, then blue Loctite on the set screws and tightened them firmly. Slide the Odin rail onto the extension and line up the six fastener holes. Blue Loctite on each screw: two at 3 o’clock, two at 6, two at 9. That finishes the rail. Last we installed the Strike King Comp. Besides a crush washer we used a couple of shims to time the brake. That was it. Fairly simple.
