Allot of us have bought them from Randy "Southern Reloading" for a great price. Message him or if you need his number holler at me. So far I have no complaints with mine and haven't heard any complaints out of the others that bought them. I know OMM and BasMstr bought some as well as Ellis.
And a side note haven't seen the Magpuls for a little more. Not by my standards. 10 pak magpuls usually run $100 and singles about $11 ea. I got my 10 Amend2's for either $7.50 or $8.00 a piece can't remember right offhand.
