These are brand new. Released just a few months back, it is Ruger’s contribution to the pistol caliber carbine market. I knew i had to have one and when I saw this one I couldnt walk away. It is a 9mm, a takedown, and it has interchangeable magwell blocks and can take the Ruger SR-9 mag, as well as Glock 17/19 mags!! It is fairly modular system. You can move the bolt handle and mag release to the right or left side, making it easy on lefties or right hand shooters. It also has an integrated rail up front for mounting a weapon light. Plastic blocks are also included to go between the stock and butt plate so you can adjust the LOP. It is heavy. Almost 7 pounds!! I’m pretty impressed with the look and feel. Only fired it a few times but hope to some tomorrow if the rain moves out. The little Fast Fire seems about perfect on there.
