Bowcaster sizing ???? (Patreon)

Guys, I need help !!!  

Does anyone know the length of wookie bowcaster ?

I have finished the model, and im happy with the proportions and all, and i hitnk you will like the assembly as well ... however i'm a bit worried that it might be a bit too big - its about 1 m in length right now  Here you can see a work in progress, but before i wrap it up i would like to check the sizing if anyone can help :)   

Thank you :)
