lower receiver/LR parts kits variations

[Paramedicjared85]

I am awaiting my ar-15 lower made by aero precision. I've found a parts kit made by del-ton which is the one I want.

My question is...will these two be compatible with eachother?

No reason why they shouldn't. The lower and the parts kit say they're all made to mil-spec.

Pretty much any mil spec lower (small pin, not those rare colt large pin lowers) will work 100% with any lower parts kit.

Although there are some lower parts kits that seem like they get shipped with slightly smaller than necessary hammer/trigger pins, thus the usual recommendation to pick up a good set of anti-walk pins.
