I have a 22" heavy Wilson barrel, 1 in 8.5 twist flat top upper on a Rock River match lower with two stage match rock River trigger gun. It has been shot less than 100 times. It shoots well 1/2 to 3/4 moa with 52gr match and 69 gr match bullets. It should shoot up to 80 gr bullets if you wanted to, but I never shot any thing heavier than 69 gr. It is $850 plus shipping. If you are interested, PM me your email for pictures. It would have to ship to your FFL.
