(Grendel) Horde Please Help Me; For I bought a Ruger!

[MaineAR]

Try using a the mag well from the x39 Ranch and using the mini-30 mags. I’ve only fired about 20rds through my Grendel Ranch, but no feed issues or needing to work the bolt hard. It’s a $30 part via Ruger, IIRC. I already had mini-30 mags, so it wasn’t too much of an investment for me. It works and the mags don’t hang down as far as the AR mags do so there is less snagging potential and it looks cleaner.
