I used the Brownells tool to true the receiver today. Pretty simple procecure. Stabilize the Upper. Oil the portion of the tool that is inserted into the Upper, add lapping compound to the part of the tool that rubs on the front of the receiver. Chuck tool up in a 3/8 drill run 15 seconds. Clean receiver and tool. Inspect to see if at least 80% of receiver has cleaned up. Repeat all steps until satisfied that at least 80% has been trued. I went to about 98%. Also got word that my stock had shipped and the buffer assembly has had the shipping label generated so all should be here shortly. Tomorrow will assemble the upper completely and the lower minus the buffer assembly and stock. Plan to shoot the upper on an existing lower Sunday with Hornady factory SST and Wolf just to get an idea of how the gun will shoot. The scope mount should arrive Saturday.
The CMMG trigger in the LPK looks pretty good and well polished. Just for drill I ran it across my oiled black arkansas ever so slightly just in case of a burr. Given the LPK has milspec springs, I expect the trigger to be a tad heavy. I am wondering if it will be a decent breaking trigger. If not I will just go with a Rock River 3 lb match. If the CMMG trigger is adequate but just a bit too heavy, I may stick it in my DPMS HBAR that currently has a trigger with about 8.5 lb pull.
