Unimag from member Aerostar

[dmurdach]

I received a new AR mag from aerostar last week to give a try in my 50 Beowulf and other ARs. If this should be in a different area Mods feel free to move.

The magazine feels solid with good construction and finish. Loading was easy regardless of caliber. I tested it in an Alexander upper mated to a YHM lower in 50 beowulf, a DPMS Sportical in 5.56, and a JSE upper with Tactical machining lower with a 223 wylde chamber. Ammo was - 50 Beowuld - Alexander arms 335gr raineir bullet, AA 350gr xtp, some handloads with 350 gr xtp and a couple of handloads with a 500gr Powrbelt; 223 - american Eagle 5.56, Hornady superformance 223, Handloads with a 53 gr Vmax, and handloads with a 69gr SMK.

Magazine had a positive latch when inserted into the guns, even with a closed bolt and full mag. It fed flawlessly in all 3 guns with all types of ammo. Even though many have said that you can use any mag for the Beowulf, I have found that most other mags dont work 100%. Standard mags would function but have a fail to feed of about 1 in 10(this is true of both the stock mags that came with the DPMS and the many Pmags I have tried). The Unimag worked just as well as the Alexander ones specifically for it. The DPMS and JSE both fed without a hitch. Mags dropped free from all guns with no hang ups.

Bottom line is, this mag did exactly as it was supposed to with no issues. I will put more rounds through it in the next few weeks and give an update on it over time as I use it more.

This is that new mag that is supposed to self-adjust to different AR calibers, right? I try to keep a supply of mags for each rifle no matter the caliber, but it might be nice to have one type to go between my 6.8 and 5.56. Thanks for the pics

Yes it is supposed to accept the common calibers. It worked great with the 223 and 50 beo.

Thank you!

Please keep it coming!

I ended up with one of these later, so here is a quick bump from an after-work range stop. I only had time to fire one mag for basic function while doing a zero check of my rifle.

This is a 6.8 SPC.

The mag looks well built and the follower concept is interesting. From first to last shot there were no issues what so ever. My zero was confirmed in the first 5 shots but I continued firing to at least give the mag a decent introduction. The last shot locked the bolt back.

No drama, just the way a magazine should be.

I'm not trying to hijack the thread, but I also received one from aerostar a few weeks back. I am hoping to finally be able to get out and put some round through it this weekend. I would like to run it through a few of my AR's in 223, 300 blk and 6.8. I'll let you guy's know my experiences with it and post a few pics as long as the OP doesn't mind.

Dont mind at all!

Please anyone who has gotten these mags please feel free to add on. I have a few hundred more rounds of 223 and 20 more rounds of Beowulf through mine and still not a hiccup. I am very pleased with this mag!
