I have 9mm SBR AR's in both Colt pattern and Glock magazine platforms, each magazine type has their benefits. I was all on on the Glock pattern at first but now I prefer the Colt pattern mags. I only went to the Colt pattern mags because I wanted a left eject 9mm rifle and Stag only makes theirs in the Colt pattern.
The Glock magazine is great if you have a bunch of other Glock stuff, but the Magpul Glock mags don't lock in on either of mine so you are stuck buying $30+ factory Glock mags that will be worn out by the metal mag catch (when worn they still work in a Glock pistol). The Colt pattern mags have a better feeding angle (the rounds sit flat compared to the Glock platform where the rounds are angled up slightly). The ASC Colt platform magazines I am using are $14 each for the 32 round, so they are cheaper than the Korean Glock mags, and they work great with a standard AR mag release. The Colt pattern are a bitch to load, so a Lula loader is required.
If I were buying into my first 9mm carbine today I would likely skip the AR and go to a CZ Scorpion. The CZ has no crap in the face, no buffer tuning issues, and it looks bad ass. The rifle is about $1000 and the mags are $20 each. Some might consider the Sig MPX, but I am not impressed with their gas to the face, the $1500 cost, or the $60 mags.
i agree go with the Scorpion, i dont have experience with their rifle but i have the pistol and i love it, got it for $750 plus the mags costed me $24 at shooters world (only place close by that had em in stock for a decent price) and yea it looks bad ass too lol
