I could be wrong but, the only problem with the Aero LPK is, if you don't have their lower receiver, you will need to get a different bolt catch pin since their receivers are threaded in that area and their kits assume you have their receiver.

Yes, they offer two kinds of kits so read carefully.

My Aero M4E1 lower receiver came with the threaded bolt-catch pin.

CMMG LPK is good to go.

I usual buy Geissele or ALG lower parts kits without trigger. Then if I don't want to spend $250 on a Geissele trigger, I order the LaRue MBT2. Which is a bargain for the quality of the trigger.

I should try this in the future
