Richard, I do tend to be vocal about something I consider sub par (my .002 opinion
) I do however run the same lever type release & AICS mags in a McRee Chassis. If I didn't take the time to explain why I prefer different I need to, it's only fair.
First point, as you all know I'm not very attracted to the look of the Uber tab sticking out (McRees, CDI etc) like a leper on on fashion week. It is cosmetic but......
Second, this is purely theoretic but well based. The mag release, on the models i've seen, is made of aluminum. The AICS mags are Steel(ish). I, among others, tend to feel the release tab will wear quickly rubbing against a sharp steel magazine. Best case, you end up with some aluminum shavings in your mag well. Worst case, after years of abuse (probably
), the release will wear to the point of in-operability becoming too short to hold the mag at the proper height to feed. Realistic? Who knows.... Possible? Dern tootin....
If you intend to run AICS mags (I sure wish they were longer) take a LONG look at the APA (American Precision Arms) DBM Setup. Well built & includes one of the best looking (& functioning) mag releases I have ever seen. Seekins also makes a great DBM, although I think (sometimes) they run mags of their own design.
Richard, here is a picture of the HS DMB I'm running on a LA McMillan A5:
