Here is the post by Chris Matthews of GA Precision(NOTE this is NOT a GAP rifle- just a personal rifle built by one of the smiths there) from his ad:
"Hey guys, I have a semi-tricked out AR-10. Has a Badger handguard, 2 10 rd, 2 20 rd mags and shoots around 1/2 MOA. My 11 year old nephew was hitting the LaRue at 600 yds with it pretty consistently with George and I spotting for him.
Has about 100 rnds down the tube.
Email me for more details"
Chris let me know the barrel is a Wilson Match with NATO chamber- plain muzzle. He was shooting Factory Black Hills 175gr through it. I have not fired the rifle, I decided after handling it- I am going to build something more like a SPR on my ar15. I have a 300Wm in AICS in a scabbard for longer distances. The AR10 with a ruck on was a little unweildy for me at 5'10" & trying to handle in close quarters. There are some marks in the finish on the lower to show it was in use before Chris put the upper together. email me at lmalternaATaolDOTcom you know the drill on the AT & DOT.
