hang on, I will go measure mine now. I love mine, perfect length for me.
Edit: without reg: 11 and just under a half Inches. (29cm)
with Myth Reg, just under 13" (32.5cm)
When I have it set up, it is the same length as my CCI L-stock on my Phantom.
Edit again: For clarity...my 22cu on my Mag, next to my Phantom w/ L-stock.
