Wanted: Beta Testers for New Barrel Band.



If this is the wrong forum or in violation of forum rules, please let me know.



I am looking for Beta Testers for a Barrel Band I have developed. It is a 3D printed assembly and is different from anything on the market currently. I utilize no clamps and no grub screws which would contact the barrel or air tube/bottle. I have developed a novel design to secure it to the rifle and have, in my opinion, designed it to be aesthetically pleasing.

I have 3 models to beta test:

  1. FX Dreamline Lite (stock shroud, stock air tube)
  2. FX Streamline (stock shroud, stock air tube)
  3. FX Crown Continuum (stock shroud stock carbon bottle)
    [/LIST=1]

    I am looking for 2 Beta testers for each rifle. If you have more than one of the rifles above… GREAT! I am in the USA so need to utilize users in the USA for the beta testing to ensure shipping times and costs are reasonable.

    Beta testers need to have access to accurate vernier calipers in the event fitment issues arise. A large part of the beta testing is to secure any variations in factory tolerances across individual rifles.

    I will send you the part(s), instructions and info on the Barrel Band, and a questionnaire.



    For participating in the Beta testing, you will receive free of charge, the final part which will include any changes made following the beta testing. For completing the questionnaire and returning that to me I will give a 25% discount on all current and future 3D printed parts once production starts. I have 6 parts undergoing testing.

    Let me know if you are interested and we can work out contact details via private message.

    Thank you in advance for your assistance.



    UPDATE:

    I have secured volunteers, thank you to those who volunteered to participate, for the Crown and Dreamline.

    Am still in need of two people to test the Barrel Band for the Streamline.
 
Still looking for Streamline owners to Beta Test my Barrel Band.

Some Barrel Bands are marketed as fitting both the Dreamline and Streamline but in checking dimensions between the 2 platforms I identified there is a slight variation in barrel shroud diameter and the distance between the air tube and barrel. This slight variation would impact elevation changes on one, the other, or both depending on the dimensions used.

I would like to ensure this was not a 'fluke' build on the Streamline I used in development.

If you have a Streamline and are interested in participating you will get the finalized production Barrel Band for free and 25% off all my 3D printed parts when and as they are released.

Thank you!

I have a Streamline but not the measuring tool that you mention. It shoots perfect as-is. Haven't done a single thing to tinker with it nor adjust anything from the factory straight out of the box settings. It's a real tack driver as-is! Reliable too! I can give input whether or not it improves accuracy or stays the same (or not). I would have 2 right now but got scammed on my second one i paid for recently so it never arrived.

Barrel bands really help the POI change session to session problem on FX air rifles, but 3D printed plastic is crap. It distorts and stretches under tension over time. It is a very low density material that must not be threaded or subjected to force concentrations like countersunk screw holes or splitting will occur. Ask me how I know all this.

Sounds like you have experience Steve-I. 

All you said is true.

A properly designed 3d printed and manufactured part can be successful. All you mention is absolutely true. That is why I design parts knowing the limitations. As far as barrel bands go, not much force is needed to secure a properly toleranced part. It should not experience high strain loads. Material selection is equally important. PLA for example is the wrong material for a barrel band application.

As far as threading the 3d printed part? No need to do that, there are many options for proper use of nuts, screws, and inserts that eliminate the need to thread directly into a part. I explore and use all these options in my designs.

A barrel band is a good fit for 3D printing if designed and manufactured properly. Will it withstand the forces of, carbon fiber, or alloys? Nope. And a barrel band does not need to experience such forces. To make parts from carbon or alloys could triple the price point. And, some parts just cant be made on a mill, or molded. I take into consideration the shortcomings of 3D prints while at the same time utilizing its benefits.

I think folks wanting to reduce POI shifts, and barrel droop will find this BB does the job better than what is currently offered. 

No doubt 3d printing has limits, but it also opens up opportunities to provide affordable parts that can not be made outside additive manufacturing.
