Very durable and practical - Magpul Industries MOE Enhanced Trigger Guard Polymer for AR-15/M4

I like this all-plastic (polymer) Enhanced Trigger Guard over the aluminum version. There is no roll-pin that is subject to breaking the frame during installation!!! There are three set-screws to screw in and it is done!!! This is A very clever design feature!!! I also like the idea that if the polymer takes A shock, there is less chance of cracking or breaking the frame!!! This is also cheaper than the aluminum version that is doing the same job of protecting the trigger any way!!!
