I have a RA Go Wild in 308 that works with AICS style mags. I picked up one from
Magpul and while it works, the front of the mag will rock in and out probably a half inch. As a result, it has issues feeding. The stock Ruger mag isn't a whole lot better, but somewhat.
I thought the Go Wild version was supposed to have an improved magwell but I got mine a couple year ago so maybe the updated it after I got mine.
If you have a similar rifle, have you had similar issues or been able to solve them? Thanks.
