Okay, I have a RRA M4 post ban that I might sell after the AWB sunsets, or I am seriously considering keeping now and turning it into a 9mm AR. My biggest question is how difficult is it to use Glock mags in a 9mm AR. I have read the FAQ and it appears that Oly is the way to go, but I have owned, Colt, Bushmaster, Oly, and RRA AR's and the only two I have left are the RRA's so obviously I love their quality and would like to stick with them. I am interested in the Glock mags because I own and love my G19 and will be going ape$hit purchasing additional mags for it when the AWB ends, including lots of G18 33 round mags. If I could use these in an AR it would be great, and if so, does anyone offer a block that will hold open the bolt after last round with Glock mags, or is that feature only going to be available with $100 colt mags. I know, I could learn to count, but I am used to that feature with my AR's and I would like to still have it. Thanks in advance for any info,
Jason.

I have not heard of an AR that uses Glock mags, but I would love to be enlightened as to such a beast.

Olympic Arms.  I had my Oly rifle(I have a bushy lower) sent to Oly for mag block installation, upper receeiver cut and all my glock mags adapted for the rifle.  I did not get it back yet.  When I do, I will post results.

Oly makes them and their new style has last round open.  Uses standard Glock magazines without a problem.
