Now that my pictures are up, here's my review. A big thanks to Marstar for their service. I will discount their slow shipping due to the postal strike.
The quality on them may look bad initially and to remedy that so those who buy these AR mags need to get a tissue paper or cloth and wipe off all the grease on them.
The rivets stick out slightly on them. The magazines are heavier than regular magazines that I have (shoulda done a picture).
The packing job sent here was excellent! I removed a crapload of the white foams already before I took a picture but you can see remnants of the in the box.
I inspected all over the magazines and have found NO manufacturer name on them....
High quality mags that's for sure. Nice and greasy not to mention individually wrapped.
I inserted one into my AR and they drop freely upon magazine eject not hang/stick up in the magwell waiting to be pulled out. They drop freely, excellent!
The weight is because they are as advertised, thick steel walls on the mags. Doesn't look to be painted black. Sorry if the pictures look a little grey but they are infact all jet black magazines with green magazine followers.
I'm impressed to say the least. Enjoy people! I hope the staff at Marstar and John will like my free review and promotion of their product!
