Is this any good? It seems overpriced. A new USC costs less. How well does it shoot? Weight, recoil, grroup sizes? Can you use 15 round MP5 mags in it? The SW45 (discontinued now) used grease gun mags, right? Where can I still buy an SW5 and what are the prices like? Can it use standard MP5 receiver mounts for sights and stuff? Can it use the MP5 RAS unit?

On HKPRO dude found a good use for one as a snow shovel about year or so ago and even had pictures.

Not trying to be a smart ass but I think your going to find the same response.

Go to the special weapons website. They have a sale until the 31st of July.  I believe the SW-5 can interchange with the MP-5. Know of several people who have the SW-5 and SW-45 and are very satisfied. BUt then I read in this forum that others have problems with it.
