Man, and I thought I was paying too much at $89.99 (in my view it is too much for what you are getting). But hey it could be worse. The Tikka CTR/TACT A1 mags are $200.00+ each after taxes.
I just don't get how something mostly made of plastic can be sold for that much. I recently was looking for a 3-round all plastic OEM mag for my Franchi .308 rifle and the cheapest (and really the only price) I saw was $85.00. For an all plastic thing that holds only 3-rounds.
I guess in the case of the SL8, looking at the bright side...could be worse...for $114 it could be a single stack... I am surprised given how Magpul has had success in third party offerings, why they haven't tried to get into the SL8 space yet...unless the market is such that it doesn't have the numbers to sustain the R&D costs...
