9mm Adapter for 556?

[Cureforcancer]

Question for the gun wizards....have any of you had experience with the 9mm magwell adapters for a 556 lower?
Is a 9mm lower a better choice when it comes to function, durability etc etc....?

A dedicated lower is always better for reliability.

However, if you already have a 5.56mm, you'd same yourself quite a bit of money.

There are a lot of decent magnwell blocks out there. If you already have a 556 lower you should go for it.

BulletGuy might be able to answer that I think he mentioned running a 9mm adapter

I have a cheap promag insert in my wife's 9mm. It works fine. The cheap pornag mags work well in it.

After that others i used sucked real bad. So i stopped selling promag shit. I cant have people mad at me.

But, the insert is $55 and the mags $15. So hell, try it. If you get lucky it is fun. If not your only in for $70.

The promag insert/mag combo holds the bolt open.

The better metalfotm mags run better but dont htbo.
