GA Precision is located in Kansas City, about 200 miles from Lincoln, NE.
George Gardner has a good following and builds primarily tactical bolt action rifles. His rifles are known for being VERY accurate and extremely durable. I've shot several of his rifles and am impressed with his dedication and products.
He'll build a long range rifle in probably any caliber you desire on nearly any action you desire.
I've shot his rifles in 338 Lapua, 300 WSM
and 308 Win all very impressive. His 338 Lapua was pushing the 300 Sierra at better than 2900 fps from a 28 inch barrel.
