The one I ordered is the newer version. It's misclassified under the M4 Bolt section, hence why I couldn't find it originally. The lack of a search function on their site is utterly annoying and rather retarded, I think. But I have it ordered. Now to see how long it takes to get here.
Anyway, thanks for the help guys. Sorry to hijack this thread. Back to our regularly scheduled MP9 conversation already in progress.
