Hello all.
I'm new here and just purchased my first AR.
It is a CDD-15.
With the DD 10" light rail
Magpul stock, rail guards, MIAD grip and trigger guard, in olive drab
1:7 chrome lined barrel 16"
F stamped front sight base and flip up Troy rear sight.

My question is does anyone else have a CDD that they have had issues with that I should know about? Parts failing/breaking, or even just things that are simple to upgrade if needed?

Thank you for any and all input,
Antonio
