My primary interest is handguns, so take what I say with a grain of salt. But I think this Ruger MPR is highly underrated on the AR Market. It looks like it sells well, but isn't discussed online very often. Ruger toughness and reliability combined with enough feature enhancements over the original AR556 to be a great shooter out of the box. I do think iron sights should come standard, but that's more of an industry-wide criticism.

Wow. Such a great rifle. I purchased it after watching mostly good reviews. Put a Romeo7 red dot on it and in 5 shots it was dialed in. I ran 223 and 5.56 through it and it ran perfectly.

All that I hoped it would be, surprisingly loud with the compensator. Quality product, great shopping experience.

Superior service from Buds with very quick shipping and tracking. Bought this to convert to a Sharps 25-45. Turned out to be an excellent hunting rifle and a pleasure to shoot. Handloading comes in real handy once converted.

I was finally able to get a scope mounted and sighted in. I shot the smallest groups I've ever been able to shoot. It's a very accurate rifle. I am very pleased with my purchase.

    Hi Douglas and welcome. No, while the Ruger AR-556 MPR is compatible with many standard AR-15 parts, including most magazines, it does not use a true "M16 BCG"; it has its own proprietary bolt carrier group designed specifically for the MPR, which is optimized for the rifle-length gas system used on the MPR model. Cheers and stay safe!
    • Answered
    Hi Jerome, this is chambered & rated for 5.56 NATO, so it will safely shoot both 5.56 NATO and .223 REM, or simply 5.56 & .223
    Stay safe & have a great day!

    Albert, even without the magazine, this cannot pass the mustard test in CT. The telescoping stock, pistol grip, and threaded barrel are all banned features on a semi-automatic rifle that is capable of receiving a detachable magazine. https://www.budsgunshop.com/feeds/state_reg/connecticut_restrictions.pdf

    Yes this comes with 1-30 rd gen M2 PMag, this is the 1st AR I ever bought and still one my favorites, it is great rifle and its built like a tank. I took off the muzzlebrake on mine and replaced it with a flash suppressor ( muzzle brake is nice but is to loud for a home deffense rifle) you will need to throw some sights or an optic on, as this rifle is "optics ready" but other then that this rifle is accurate, reliable, and fun to shoot as any out there.

    Henry, yes Sir. This Ruger AR-556 MPR has a Magpul MOE SL collapsible buttstock on the Mil-Spec buffer tube. Cheers!

    Buds has said that if the capacity is the only issue they will remove the mags and ship the firearm without it. They don't swap them, but you can still get the firearm and then get the 15rd or less mags locally or online.

    Gabriel, No the muzzle device is not pinned or welded on. The rifle has an SBN treated threaded barrel that can have any 1/2-28 thread pitch muzzle device installed.
