Matt at JSAR machined me up a custom choked .22 LW barrel with standard rifling for my P15. His machine work is second to none and nicer than any factory barrel I've seen so far. Being the the .47 diameter I had to use some brass hobby tubing to shim inside the barrel bands. I normally always go through a barrel before installing but didn't feel the need for it because this barrel looked so good in fit and finish. The results speak for them selves. These are 5 shot groups at 50 yards resting in a window sill while sitting on steps using 16grn JSB's.
