The only issue I had was using Win white box 45 gr. HPs in an XCR mag, the flat meplate would pile drive into the tapered ring that guides rds into the chamber causing an FTF. Switched to spire point ammo and havent had a single hiccup since. The reliability is incredible, something much more expensive rifles struggle to match. Its nicely balanced and points well, recoil is very mild. Its nice and lightweight too. That being said the controls are not very user friendly. Mag changes can still be done fairly quick but nothing like an AR or even a VZ. The stock has alot of drop, along with the fixed rear sight makes mounting magnified optics a challenge. A Bushnell TRS-25 will lower 1/3 cowitness the irons but thats about it. Cheek weld will suffer with any optics, a cheek riser is a good investment. I dont know what the hell Benelli does to those barrels but Ive never seen a thin barrel hold POI and groups together with tons of heat like the MR1. Copper fouling is also incredibly minimal. The gas system is basically self cleaning and self adjusting to any load Ive tried. Quality is what you get with the MR1, its a rifle you can shoot and shoot and shoot until you run out of ammo without worrying about stoppages or POI/group shifts due to barrel heat, or even cleaning the damn thing after every range trip. It will not keep up with an AR, XCR or VZ on a course, or get all dolled up in koolaid so pick your use then pick your rifle. This one doesnt do it all.
