"A great California Legal barrel"

John on 10/19/2015 9:25:25 AM

Overall Product Rating:


I just received this barrel in the mail last week, went out shooting with it this weekend and I was really impressed by the tight groups that I was shooting. I bought the 6.1 inch version and I am thinking this shoots better than my factory MK23 barrels. Very impressed. Glad to see a seller step up and build us a barrel that is of quality and that we can use in California.
