CHEERS
No. I wish they could. The mags will fit but they won't engage and stay. Years ago, I heard that there was a universal mag made as an aftermarket item but I never saw one.
AR mags are too wide and there's a lot of grinding and drilling to get them to work. Ruger's web site has them, and they're shipping out 30 round mags, too. You can get mags made by Promag for about half the price of Ruger's. Get the metal ones, the plastic ones aren't very good.
