Bitzenburger Fletching Jig Upgraded Nock Receiver by Zenith Archery

Zenith Archery Products Bitzenburger Upgrade Kit Zenith Archery Products has introduced a new upgraded nock receiver for your Bitzenburger fletching jig. The replacement body will fit directly into your jig and will still adjust for all three different fletching patterns. The original receiver held the arrow only by a loose fit on the nock. The new receiver comes with two inserts which are held into the body by a long screw which is tightened through the rear of the receiver and will hold the arrows directly, without slippage. One insert is sized to fit snuggly into any arrow which uses a G nock.  The second insert does arrows which use pin nocks, holding the pin by the hole in the insert. It also does arrows which use Super nocks (.246 carbon, Super Uni-bushings, etc.) by fitting the insert into the back of the arrow. If the pin holder becomes too loose, just gently squeeze the segments together with a small plier until it holds the pin tightly again.  This kit DOES NOT include a sleeve for X or H nocks.  These are available as an option if needed.  An adjustable upper support plate is mounted using the template and hardware included with the kit. Once the arrow is mounted in the jig, the plate is adjusted to support the upper end of the shaft. Older arrows with glue on nocks can still be done using the old receiver.  This will not work with crossbow bolts.  There was a change in design by bitzenburger around 25 years ago and this may not work with jigs older then that.

    This totally changes the way that you fletch arrows. It allows for a huge degree of accuracy. Every arrow is now identical. Super easy to attach.

    Zenith Bitzenburger Upgrade Kit

    I’ve had my Bitz for several months, I don’t fletch a lot of arrows and it worked fine as it was but once in a while my fletchings were off. After installing the Zenith upgrade it’s like a different fletching jig. There’s no deviation because the arrow shaft is firmly held in place. I had the option to buy the upgrade when I bought the jig and clamp but passed on it. Buy this now, you won’t be disappointed

    Bitzenburger Zenith Upgrade

    Product is machined very well and with all the adapters and sleeves there shouldn’t be any arrow the Bitz Jig can’t do with extreme precision now. Easy to change between adapters, takes about 15 minutes to install at most. Worth the money and time invested.

    Zenith upgrade for Bitzenburger

    Posted by Doug on Jun 17th 2019

    The upgrade is very well made, I use it with pin nocks in my shafts and get very constant fletchings, I know own 2 jigs and have no reason to switch, this jig does it all!

    I can't believe I ever used my bitz jig without this. What a difference. Every arrow is exactly the same now.

    Bitzenburger Upgrade Kit

    I have been looking at buying the BitzenBuger Upgrade Kit for several years now, just couldn’t bring myself to do it. Well I bought it last month and what a difference it made, wish I would have bought it a long time ago. Installation of the Upgrade Kit: Simple took me about 10min. just remove the old knock holder slide the new one in and secure it in place. The arrow holder at the top of the jig: Your provide a templet to place on the jig so you know where to drill the holes. Once drilled just screw the new arrow cradle on to the jug and set where desired. That’s it you’re done. Fletching arrows: Just remove the nock from the arrow slip the arrow shaft down over the pin and it’s secured in place. Unlike the old knock receiver there is absolutely no play in this system. Then just fletch your arrows as normal. After fletching arrows: I fletched six arrows the spacing between vanes is evenly spaced all the way around. The space was never consistent between all three vanes with the old system. I took the arrows out and shot them all the way out to 70 yards and I swear they were flying straighter. They definitely are dead quite in flight. Before there was noise coming from the arrows as they were flying to the target. I only brag about a product when I truly believe in it. So if you have not purchased this upgrade kit you defiantly want to. I purchased mine from 60x on here.

    Excellent product, great upgrade over the original. Arrow stays put, no jumping out of the nock holder. I really didn’t need the attachment at the end that you drilled the holes for but I think that is for a smaller/narrow arrow. I would say the instructions are non existent. be careful removing the old assembly that you don’t lose the spring/bearing in each of the 3 positions on top that adjust the different fletch settings.

    This is great. Pop out the nock, choose the adapter that fits your particular shaft, get to fletching. This is definitely an upgrade and ensures fletching accuracy, The one draw back, I need a few of the adapters for H, S, GT, and G sized shafts. I wish I could have purchased a single adapter, but I had to purchase another upgrade kit. Not a huge deal though.
