Here is the M&P 15-22 as it sits in its current form. I removed the Leupold 2-7x rimfire scope from my Ruger 10/22 and using an A.R.M.S.#5 Multibase mount with Warne 1" rings, the Leupold has found a new home. I overlapped the handguard rail with the mount as I couldn't obtain the eye relief I wanted without doing so. Some say the optic mount should only contact the receiver rail. I haven't experienced any issues that I can trace back because of this configuration. The A.R.M.S.#5 Multibase is one heck of a rugged mount. I can't see it flexing.....and even if it could, it's not likely to make much of a difference at 50 yards, IMO.
