Magpul is a great company making high grade products from the simplest innovations... they work!
They are making other products now as well... cell phone protector. Really nice and simple:
Just as with the magazines you can get a good grip. Not rubbery.
The little red circle is not part of it... Steelie system but works great with Magpul.
As with everything else Magpul makes, Made In America.
