Best weapons to pair with Mag of Holding?

I got my hands on a few mag of holding acquisitions, I tried out the RGL first and just laid waste to t3 and dark aether with it 🤣 was wondering what other people think may be the funnest use of this. Spamming snakeshot tyrs I imagine is good, or most SMGs. I also thought you could build a solid gun like the SVA, put the smallest mag on it for all the movement/ads/benefits etc, then mag of holding it for unlimited mag size for a super mobile gun
