PNA - 1 Dozen Pin Nock 0.245 bushing/insert no nocks

Pin Nock 0.245 bushing/insert No Nocks fits 0.244 and 0.246 ID shafts.

Everyone Tunes their arrow spine by lightening your point or going to a heavier point, Pat likes to be able to adjust weight on both ends of his arrow.

Now you can micro tune the nock end of your arrow,  If you need your arrow a little bit stiffer spine you can change Pin Nock bushings to heavier weight Pin insert's.

Pat had custom weight pin inserts manufactured for Pat Norris Archery.

11grain bushing is our standard, it is a little shorter overall and has a shorter taper, and is hollowed out.

The 19 grain bushing is a little longer overall with a longer taper and is hollowed out.   

The 27 grain bushing is longer overall and has a longer taper, but  has not been hollowed out.

You can now just stiffen  and micro tune your arrow a little bit without going to a heavier spine arrow.

Take a look at my Arrow Testing Kit to try a couple of separate spines and point combinations.

Pat says HAPPY TUNING!
