So I got my LR308 back from the gunsmith yesterday. Had the 24" bbl shortened to 20", a JP large profile brake installed and that bright chrome barrel moly-coated black. Barrel/chamber were lapped to clean up any tool marks. Had all the tolerances checked and trued up in the gas system as well.
This thing shoots much better now, and with the brake you can spot your own shots and watch your own vapor trails. There is almost no recoil at all now... Probably right around a 223, if not less. This thing shoots lights out now. Below is a target that is 10rds at 200yds. It measured just over 1/2in in a variable cross wind averaging at ~6mph. Couldn't be happier with the rifle and how it shoots now.
Still have some things to do. Because of the non-standarization of the large frame AR, handguards can be hit or miss. So it's going back to get the handguard machined on a CNC machine to lighten it up, and allow for better air flow and get a nice custom look to it. Also going to add a JP captive spring recoil buffer to get rid of the cheese grater twang. Also have an AAC 762-SDN suppressor waiting for approval.
Here is a list for it for what's gone into it:
Leupold MK4 6.5-20x56, 4" Sunshade and alumina caps.
Leupold MK4 AR Base
Leupold MK4 single piece rings.
Timney single stage skeletonized 3lb trigger
Magpul PRS Stock
Accushot monopod
Harris BRM 6-9" Bipod
Ergo DLX palm shelf grip
Ambidextrous charging handle latch
