I noticed in the FAQ on your website (and it was an outstanding redesign, by the way!) that the FHMB is not an NFA item.  Can you purchase these separately now so that you can mount the suppressor to more than one rifle?  

If so, can you post an MSRP?  

On the old design (Gen IV?), there was a part that could be replaced; does the new FHMB use a similar part and if so, what is its replacement cost?

One last question...I seem to remember seeing a version offered in titanium - is that still an option?

Thanks!
