G – 4 mm – .165, .166, and .168” ID: (Micro diameter arrow)
X – 5 mm – .204” ID:
H – 6 mm – .233” ID:
S/GT – 6.5 mm – .244, .245, .246” ID (Standard arrow)
As you can see that even within the specific arrow size categories (specifically G and Standard (S/GT), there is a slight variation between arrow manufacturers. Also, you might be surprised to learn that two identical arrows can vary slightly in size making achieving a perfect fit on every arrow an almost impossible task for an archery accessory company (like NOCK OUT) to achieve.
The good news is that with a little effort, you can easily achieve a custom fit for your quiver full of arrows. Below are a couple options for making custom fit adjustments. We have also provided step by step video instructions. And, as always, we are just a phone call away and more than happy to assist you.
We have identified three excellent ways to achieve a custom fit on your micro diameter arrow.
With the G (4mm) micro diameter arrow, no orange bushing is necessary. The nock fits directly into the arrow. If you have a .165” arrow (Black Eagle and Bloodsport), no fit adjustment should be necessary. If you have one of the larger diameter micros (.166+” ID) such as an Easton or Beaman, you will find that right out of the package, the nock is a little loose in the arrow. Below are your options for achieving a custom fit.
Hot Melt Glue: Apply a small amount of glue to the nock receiver and press into place. Allow to dry and test the fit by pulling on the nock as if to remove it. Follow glue manufacturer’s instructions for removal.
Bag trick: The old tried and true plastic bag trick is a terrific way to improve nock retention without using an adhesive. Simply lay a thin plastic bag (such as a sandwich bag or a grocery store shopping bag) over the shaft opening. Press the nock receiver into the shaft taking the bag with it. The bag will fill the gap and give you a nice snug fit.
Crimp: Holding the nock in your non-dominant hand, take a pair of pliers and gently squeeze or crimp the end of the nock receiver. It only takes a very small pinch to adjust the fit into the shaft. Crimping too much will damage the receiver. Start with a tiny adjustment, check the fit, and adjust further if needed. Adjust until when you press the nock into the shaft, you notice that the fit is greatly improved.
We highly recommend that you watch the video on this procedure before attempting.
We have identified two excellent ways to achieve a custom fit on your standard size arrow.
All standard size arrows will use the largest of the three orange bushings. On standard arrows with a .244” ID, you should fit the fit to be nice and snug with no adjustment needed. On the larger standard arrows (Victory, Easton, and Gold Tip) and adjustment may be necessary. The nock fit directly into the arrow. Below are your options for achieving a custom fit.
Hot Melt Glue: Apply a small amount of glue to the nock receiver and press it into the bushing. The glue add just enough volume to allow the nock/bushing combination to fit snugly. You will also be able to remove the nock as it has not been glued into the arrow shaft. Follow glue manufacturer’s instructions.
Bag trick: The old tried and true plastic bag trick is a terrific way to improve nock retention without using an adhesive. Simply lay a thin plastic bag (such as a sandwich bag or a grocery store shopping bag) over the shaft opening. Press the nock receiver into large orange bushing and then press the nock/bushing combination into the shaft taking the bag with it. The bag will fill the gap and give you a nice snug fit.
NOCK OUT Lighted Nocks should fit snug into the arrow, but not so snug that they are very difficult to press in or remove. If the nock feels to tight, please contact us for instructions before you press in so hard that you crack or otherwise damage the shaft. The nocks should never be so loose that they either fall out or easily pull out of the arrow shaft. The term we use is “snug.” The nock fits in snugly and stays in place, but can be removed without using any tools.
