Best mags for mpa chassis- .308

[BuildingConceptsllc]

So, I just bought an mpa chassis from a fellow hide guy. I have a barrel blank coming for my Smith and I got a TL3 from another hide guy. Now I'm reading about mag/feed issues on mpa chassis and I don't know what mags I need to get for my .308 build. I'd rather not be doing any tweeking of any mag lips ect... but I guess I will if need be.

P.S.- I will get a pre-cut barrel also but this is a special circumstance I worked out with my Smith.

You're worrying about a problem that may not even exist.

Buy some AICS mags and see what happens.

I wouldn't say I'm "worried" about it, but I'd rather get whatever mag works best from the jump and spend my time doing things other than messing with mag lips. But, that's why I asked. What I've read about was a few years old and it didn't seem like any widespread issues then, which is why I asked about it. There's a ton of mpa chassis being used by guys on here so why not ask?

MDTs work perfect in my MPAs and Impacts shooting .308 and 6.5.
But, install these, they will solidify the fit: https://masterpiecearms.com/shop/mag-block-insert/
Also, AICS work fine, bet tend to have more side play. YMMV.

Get AICS/MDT/ARC etc.

Even if you have to tune mag lips, who cares? It takes, what, 30 seconds maybe?

I don't really know but if that's all it takes then I don't care. Some made it sound like a much bigger issue

It's not. A pair of calipers and a home built tool (using wood) or a MPA feed lip tool and you're in business quickly.

I tuned 12 brand new MDT mags the other week in less than 5-7 minutes. Filled them up with dummy rounds with my exact load spec, fed flawlessly. Used them in a match (1-2 mags per stage + zero) last weekend, worked 100%.
