Not worth the money.
When dropped the floor plates, Yes there are two. Unlock and you have to put humpty dumty back togther again!
They are very destructible and dent easily in addition to coming unglued.
Oh! and the feed lips bend when dropped causing feed problems, so whip out your tool and bend them back somehow. And like your dented car they never bend back right.
They are also heavy, since they are made of steel. The long ends are butt welded continuously so unlike USGI there are no spot welds.
Start carrying them all day and the extra pound of steel becomes noticeable, unless you loose weight to compensate.
They must be over priced since I don't see anything about them that warrants the asking price. Just a lot baloney. Now that I have and have seen I want my USGI aluminum mags back.
