Home Forums Hunting & Shooting AR and Tactical Rifles Couple of lessons learned

I am planning to build my first lower and ran across this thread.

I bought the following items:

Aero Precision lower from Creedmoor
Parts kit and stock from White Oak Armament
Geissele Service Rifle trigger from Primary Arms.


First question is, even though they are already purchased, are there any issues with the parts I have purchased? I own other Geisselle triggers and have been happy with them and it is my assumption that John Holliger would sell good parts.

Second questions, are there any tricks or tips for assembling a lower.

Any input would be welcomed.

And this lower will be used for Highpower competition if everything works out well.
