For sale is a take off barrel from a Sako AV rifle chambered in .270 Win.
The previous owner had shoulder surgery and had the barrel ported. This is similar to a magna port where the original barrel was used instead of adding a conventional brake.
Minus the ported area, the barrel length is ~20in. My daughter did shoot with this barrel with very positive results 1.4" groups (16yrs old). Bore is in excellent shape.
Price is $35 shipped
