I have a 9mm mag block that fits and operates perfectly in every brand lower I have except for my 4 Noveske lowers. It won't fit in any of them. I am wondering if anyone has a 9mm block that fits and works on your Noveske lower. If so, what brand is it? Doesn't matter if it's glock or colt. Thanks!

What brand mag block are you using ??


What did Noveske tell you when you called and asked them about it ??


What were the dimensions  of the magwell and the mag block when you measured them ??

I don't have a 9MM mag block but I used the Redi-Mag adapter which allows the use of S&W MP 15-22 mags in a standard lower with CMMG bolt.  It would fit in most magwells but some it would not.  Redi-mag suggested sanding and fitting their adapter as necessary to fit the magwell.

It may be that you have some sharp corners on the 9mm adapter that just barely won't let it slideinto place.  Make the adapter fit your magwell if you intend to use it on that specific lower.  Surely it can't be that far off if you can put magazines into your Noveske Lowers.  Or just use a lower that it fits in.

What he said ^^^

My BMA would fit in all my lowers but the Aero lower because the inside corners of that lower are slightly radiused.  I had to sand the corners of the BMA slightly to fit the Aero, but it had no effect on the fit in the other lowers.
