I am not a big fan of the entire MOE series of products from Magpul. The quality you see in the rest of the Magpul line is not show in any of these products.
Well I agree with you about the MOE grip, have it, don't love it, gonna change it out soon. As for some of the other products in the MOE line they are much better (IMHO). I have the MOE stock and love it, it is identical to the CTR except for the friction lock and the sling attachment point. Same material, same build quality, same thing with a few less features (which is the point). Also have heard nothing but good things about the MOE handguard (except for bikerRN but I think he got his issue fixed).
What issues did you have with the rest of the MOE line?
