So..... I own an AE MkIII and am super happy now that I've tweaked the trigger a bit, modified my Spuhr rings to fit and gotten the chassis torqued properly to eliminate cold bore issues. I know the dimensions of the UK barrel that came on it. Is it unreasonable to ask the dimensions of a product that I wish to buy? I guess I can avoid the veil of secrecy by simply measuring what I have and turning a barrel sourced elsewhere as I wish. I didn't think it would be a big deal to ask but even here it seems vague. Thanks for any input those in the know are allowed to divulge.
