@LobsterClaw207 I originally picked my Scorpion up at a fantastic price (pro deal) and like many others I bought it for that backpack/briefcase long gun role. I ran some testing on the range and what I found was this: on B/C steel my advantage point was about 100 yards. I.E. unassing the scorpion from its carried position and status and getting one hit on steel versus drawing my pistol from concealment and getting one hit on steel. I don't have the times off the top of my head, but they were close enough that I was convinced I didn't really have an advantage in terms of accuracy at distance until I got to that ~100 yard mark. It also wasn't buying me much of anything ballistically given I am still slinging the same 135 Critical Duty round at only a few more FPS.
I was turned on to the rattler by some other folks. Im at the same place with it reference my above comment about single round hit on steel. However, it fills some other niche mission sets perfectly do its excellent ballistic properties as compared to similarly short 5.56 setups, as well as bringing way more to the game than a pistol. The 110 GMX out of it is not to be fucked with. I took it to a vehicle ballistics lab and shot it head to head against the 135 critical duty, and the 55GMX barrier out of our 11.5s. I'd take that 110 GMX every day over all of the above working at relatively close ranges around intermediate barriers, including the 55GMX out of ol faithful.
In regards to price, the CZ pro deal is one of the better in the industry. I got zero pro discount on the rattler and would still recommend it if you are looking for a working gun. Regarding the mags, early issues with the Scorpion mags were numerous due to them hanging in the gun on the locking tabs. Some dremel work sorted it out with no issues since then. I do not have any, but understand the aftermarket mags as well as current production Scorpion mags don't suffer the same issues if you were to purchase today.
