Magpul has released a new rail mounted QD mount called the RSA QD.
I thought this might be a good choice for me, so I ordered some. Haven’t used it much yet, but so far I like it.
It has rotation limiters, which I really like. However what I don’t care for is that it uses up 3 rail slots. Here is a picture of one half of it sitting on top the rail.
I really like how it is low profile enough to mount under the cantilever part of a LaRue Scope mount.
So far I really like it and would recommend it.
